How to put air from the heating battery. How to literately pull the air from the heating radiator? Signs of aerial traffic

Residents of private houses and inhabitants of urban apartments are regularly faced with the problem of delivered batteries. Especially often this phenomenon occurs at the beginning of the heating season or during repair work. Of course, you can call plumbing from the management company, but it may be possible to wait for quite a long time. How to pull the air from the battery yourself and restore the health of the heating system?

Signs of aerial traffic

It is possible to understand that air has accumulated in the battery, it is possible for several signs:

Uneven heating radiators. It may touch a separate battery or the entire heating system of the apartment. In the first case, the delivered part of the radiator will not be heated. In the second, the plug will interfere with the normal circulation of the coolant through the system, why some batteries will be hot, and others are significantly colder.
Hissing or bugger in radiators is a clear sign of the presence of an excessive air in them.

What is dangerous air in the battery?

Before you understand how to release air from the battery, it should be understood as he got there and what is dangerous.

In addition to reducing heating efficiency, air appearance in batteries may result in the following problems:

Metal from which radiators are made, with air contact more corrosion. Therefore, the service life of the heating system is significantly reduced.
The difference in the temperature of various elements of the pipeline can lead to its destruction.
The resource of the circulation application is significantly reduced. Under normal conditions, its bearings are in water, when air intake significantly increases friction, leading to the device breakdown.

Causes of reinstateness of batteries

The reasons for air entering the system can be several:

In an apartment building, it happens most often when the system is filling in the coolant. According to the rules, the process should be carried out quite slowly, with constant air blending, but in reality is not always the case.
Incomplete tightness of the heating system. In this case, you will have to burst the air constantly until the disadvantages are eliminated.
Conduct various kinds of repair work. If at least a partial palate pavement was produced, some amount of air will inevitably fall inside. Therefore, after such events, it is necessary to lower the air from the heating battery.
Low quality coolant: Increased content of air dissolved in water can lead to the formation of an air traffic jam.

Elimination of air traffic jam

Special valve, located usually on its end, will help to store air from the battery. In old models you will need a radiator key. In modern models, Maevsky crane is installed, to work with a simple screwdriver or a special small metal or plastic key, which can be bought in a business or construction store ..

The sequence of actions is as follows:

To the radiator you need to substitute a fairly roomy container. When air bleed from the battery, some kind of water will be set out. It is better to not allow it to hit the floor.
In the films and in life, you can observe the podplikovy water, wet from the head to the legs. Indeed, this operation may be accompanied by splashing water in the system under pressure. It is not only unpleasant, but can also harm the walls of the walls or furniture. It is quite simple to solve the problem: you need to hang on the valve with a rag that will delay all the splashes, and water quietly stalks in a bucket or a basin.
A key or screwdriver carefully unscrew the valve until the clear hiss of the outgoing air is heard.

As water starts, water will begin to drip. We must wait until it does not stick with a thin trickle. The crane can be closed as soon as the air will stop bubble in this jet. Usually this operation takes 5-7 minutes.

Council. If you do not want to repeat the air boom procedure too often, then follow the advice of professionals and take a minimum of 2-3 buckets of water. This will be guaranteed that the air from the radiator is completely removed.

Very convenient device - automatic air vent. Here the procedure takes place without any participation of a person: when air accumulates, the float is lowered closing the drain hole. After the breaking of the float returns to the place. An essential drawback of such devices is increased demands on the quality of the coolant. Therefore, in apartment buildings with centralized heating, they are rarely installed, as they quickly fail.

And if there is no shrink valve?

Sometimes there is no drain valve on the radiator. It usually concerns old cast iron batteries, where his role is played by the plug. In this case, the work is complicated, but not so much so that it is impossible to fulfill it yourself.

It is necessary to stock up with a gas or adjustable key, with which you can unscrew the plug.

Important! Be sure to overlap the access of the coolant to the radiator from the riser. This is done if the plug turns completely. The water pressure then simply will not allow it to insert it into place, and this will be wrapped by subloping of neighbors.

The main problem is that usually the plug prevents the thick layer of paint and hardened pacle. It is possible to solve it using kerosene or lubricant for threads. We apply it to the connection and wait for 15-20 minutes.
Gently turn the cap and descend the air in the same way as in the case of Maevsky's crane. Do not forget about the container for water and about a rag that prevents splashing.
When you twist the plugs, you should not forget to apply the seal on the thread, for example, FUM tape to eliminate the leakage of the battery in the future.

To facilitate this difficult task, many owners put a regular crane in the past in the past. He did not add aesthetics, but the procedure facilitated significantly.

In private houses, an expansion tank is used to eliminate air traffic jams. After the water descending, the faucet opens, and in most cases the plug disappears. If this did not happen, it is recommended to increase the temperature in the house so that the coolant boils. Then the problem of delighting will accurately disappear.

To ensure a guarantee, it is enough to carry out an excess air whipping procedure for all batteries twice. After that, the heating system will function normally.

Understanding how to pull the air from the heating system will help not stay in winter without heat

There are no cases when the radiators are suddenly stopped during the heating season. One of the reasons for the system failure is a air traffic jam, and then a problem arises before tenants, how to lower the air from the heating battery to restore the circulation. There are several effective ways to normalize heating and how to lower the air from the system. At the same time, the procedure should be determined depending on the type of heating system and the particular air accumulation site.

The appearance of air traffic jam

It is easy to find that a heating system has been formed in the heating system, easy enough. Signs of importing system:

in pipes and radiators, bubble sounds are heard;
batteries or do not warm at all, or heated only to half;
in some rooms it is hot, and in other heat does not pass.

It means that the air has become blamed everything, and how to pull it out from the heating system, you need to decide according to where it was accumulated. Air bubbles always accumulate in the upper part of the heating system, so most often cooled radiators in the premises on the last floor. To find the location of the air plug location, you need to consistently feel the feed pipeline and all batteries by checking the degree of their heating. Also advise to pull the pipe with a hammer and determine the sound where emptiness originated, but it should be done carefully, so as not to damage the paint layer on the pipes.

As a result, finding a problem place, you can already choose a method, how to descend the air from the heating radiator or, if necessary, from the pipeline.

The air cork not only prevents the circulation of the coolant, but provokes corrosion of metal pipes. The presence of air in the system negatively affects the operation of the circulation pump.

Where the air appears in the system

The reasons for the formation of air traffic can be both natural and associated with improper design of the system and poor quality installation.

Naturally emerging reasons:

when heating the coolant is released dissolved in the liquid air, it rises up and forms a plug;
gas bubbles appear in the process of reacting hot heat carrier with some types of metals (in particular, aluminum);
due to evaporation, the liquid level in the open expansion tank is reduced below the critical value;
air does not have time to completely exit pipes and batteries when it is too fast filling with water difficult to configure the system.

It is important to know how to pull water from the heating system if necessary and then fill it again so that in this case, the air remains in the pipelines and radiators.

In addition to natural reasons, the appearance of air traffic jams also leads:

incorrect layout of horizontal pipes and installation of radiators;
pressure drops in the feeding water supply;
poorly sealed compounds;
worn out of old pipelines;
fault of the expansion tank.

When during the operation of the heating system, it turns out that it was originally designed incorrectly, it would have to redo it. But to urgently restore the flow of heat, you need to decide how to pull the air from the heating system.

Elimination of air traffic jam

If the heating is properly designed, then how to pull the air out of it, will not be labor. You can arrange so that the booming air blending will occur automatically, as it accumulates. For this serve special devices - air vents installed at critical points. In other cases, you need to purchase skills, how to lower the air from the heating system in manual mode.

It matters:

open or closed system type;
natural or forced coolant circulation;
upper or lower version of pipe wiring;
are the slopes of pipes horizontally compliant.

Radiator Radiant Crane

In apartment buildings, residents do not have a question how to pull the air from heating, the specialists of the management company should be worried about it. Although the heating is so arranged in the old five-story buildings that it is possible to pull the air from it only through the radiator in the apartment of the upper floor, and this periodically accounted for the tenants. More acute the problem of mapping for owners of private houses, having autonomous heating - the air is periodically necessary to pull the air. To lower the air from the radiator of water heating, the needle air valve is used, the so-called. Crane Maevsky. Such a device is installed in the upper end of the radiator battery, instead of a plug. Sometimes it is also used to descend the air from the tube of the heated towel rail. Various models of Maevsky cranes are somewhat different, so before you pull the air in heating radiators, you need to get acquainted with the instructions. Open the valve of the crane or a horn key, or a conventional screwdriver, or just with hand.

Consider how to drain the air stop from the heating battery with the help of Maevsky's crane installed on it:

prepare tools (key or screwdriver) and water collection capacity;
open a completely thermostat, then unscrew the crane of Maevsky to the half turn;
air will begin to go through the valve with a slight hiss;
substitute the container and keep the valve open, as it is necessary to lower the air from the heating radiator until water flows;
when a dense weaping of water can be tightened.

If, after you lowered the air from the heating battery, it is still poorly heated, drain through the same crane of the 200 coolant gram to finally remove the air stopper.

Sitting the air through the expansion tank

In private houses, the device of heating systems can be different, it depends on the features of the planning of buildings. For different types of systems, appropriate expansion tanks are used - open or closed. Therefore, individual homeowners more often have to think about how it is more expedient - to lower the air from the heating radiator or through the expansion tank .

In the open type system, air bubbles have free output through the expansion tank installed in the attic. If the heating is working normally, the air from the system is not necessary, since it comes out itself. But the liquid gradually evaporates, and the water level in the open expansion tank can fall so low that an air stopper will appear at the top of the feed pipeline. In this case, the circulation of the coolant will slow down or completely stop, and in this situation it should be about how to pull the air from the heating system.

To drive out an air stopper, you can add water to the expansion tank on top, but it is better to replenish the volume of fluid in the system through the bottom crane connected to the water supply system. The water coming from below will fill the emptiness in the pipe and squeeze the air out through the opening of the expansion tank.

During the heating season, it is necessary to ensure that the expansion tank is constantly filled with water by approximately 2/3 of the volume, and with a decrease in the level of water.

In closed systems, membrane expansion tanks are used. Sometimes there is a break of the membrane, and then the air is entering the system. If it is possible to establish that the reason for carrying is a faulty expansion tank, it will have to be replaced. But before starting repair, before the water from the heating system, you need to prepare everything you need to leave the house for a long time without heat.

What should be the right system of the system

When designing, it should be envisaged that air can accumulate in horizontal pipes, and how to pull it from the heating system will be a difficult task. Therefore, it is important that the top feed pipe has a small bias, ranging from the riser and then along the movement of the coolant. At the highest point, a device is installed that allows you to lower the air from heating. It can be a regular crane or crane Maevsky, but it is better to use an automatic air vent. In a more complex configuration, the heating system the air vents are mounted in all places where the problem of vesting can occur. Then the question will not arise how to lower the air in one or more heating radiators, since the accumulating bubbles will be pulled out from each group of the components of the system of elements.

The return pipe must be laid with a slope towards the boiler. This is done to combat air traffic jams, as well as in order not to guess what way to pull water from the heating system when repairing the repair.

If the heating system is equipped with a circulating pump, then there is no need to comply with the slope of pipes. And yet, for the efficiency of the system, it is desirable to lay pipelines with the right slope.

Finally, you can recommend that you always apply to specialists about problems with heating. They know how to design a working system and advise how to pull the air accumulated in heating radiators. But the homeowners themselves should have the on the eve of the heating season to produce a prophylactic inspection and verification of their heating system.

Removing air traffic jams from the heating system: how to lower the air from the radiators?

Air in the heating system is an obstacle to its normal functioning. With this problem, residents of apartments and houses face, as a rule, at the beginning of the heating season. Noise in pipes, cold batteries, corrosion of metal elements - this is the result of the formation of air traffic jams. And this happens even with a perfectly designed and properly mounted heating system. Why this happens and for what it is necessary to make air removal from the heating system in a timely manner - this will be discussed in this article.

Why does air appear in the heating system?

Many of our compatriots are familiar with the concept of "air traffic jams". This phenomenon is remembered at the beginning of the heating season, when warmth is drunk in the houses, and in the apartments of the upper floors, the batteries are often not heated or heated only at the bottom, and in the upper - absolutely cold. Where does the air appear in the pipelines? The reasons for bringing may be several:

repair work (assembly, disassembly of the pipeline), during which air appearance is inevitable;
non-compliance during installation of the magnitude and direction of the linker of pipelines;
reduced pressure in the water supply: water level falls, and the resulting voids are filled with air;
when water heated, the bubbles contained in it are highlighted and rising into the upper part of the pipeline, creating air traffic jams there;
the heating system is incorrect: after summer downtime, the pipes should be filled with water not quickly, and slowly, producing simultaneously moving the air from the heating system;
unsatisfactoryly sealed joints of pipelines through which the coolant leak occurs. The flow in these places is unlikely to flow, since hot water is immediately evaporated. It is through loose seams and air to the system is suused;
fault air intake devices;
connecting water "warm floor" to the heating system whose pipes are located at different heights.

Air traffic removal methods

Since one or more of the listed factors may be present in many homes, then the issue of air removal in the heating system necessarily faces. This operation can be performed in various ways. It all depends on which circulation of the coolant is dealing - natural or forced.

In the heating system with natural circulation (meaning the upper pipe wiring), the resulting air plug can be removed through the expansion tank - it is in the highest point in relation to the entire system. The supply of the feed pipe should be made with a lift to the expansion tank. With the lower layout of the pipes, the air is removed in the same way as in heating systems equipped with a circulation pump.

Wash air from the heating system with natural circulation using the expansion tank

In heating systems with a coercive coolant circulation mode at the highest point, an air collector is installed, specially provided for the air descent. In this case, the feed pipe is paved with the rise in the coolant rate, and the air bubble-rising bubbles are removed through air cranes (they are installed at the highest points). In all cases, the return pipe must be laid with a slope in the direction of draining water for accelerated emptying if repairs are needed.

Types of airlighteople and places of their installation

The air vents are manual and automatic. Manual air ventures or cranes of Maevsky have small sizes. They are usually installed on the end of the heating radiator. Regulate the crane of the Maevsky using the key, screwdriver or even manually. Since the crane is small, then its productivity is small, so it is used only for local elimination of air traffic jams in the heating system.

The air vents for the heating system are two types: manual (crane Maevsky) and automatic (work without human participation).

The second type of air vent - automatic - work without interfering. They are installed both in a vertical position and horizontal. They have high performance, but have a sufficiently large sensitivity to pollution in water, so they are mounted along with filters and on feed pipelines, and on the reverse.

Automatic air vents are installed in the heating systems of a closed type through the line of pipelines at different points. Then the reset of air from each group of devices is made separately. The multi-stage monitoring system is considered the most efficient. With proper laying and competent installation of pipes (under the desired slope), remove the air through the air ventures will simply and trouble-free. Removal of air from heating pipes is associated with an increase in the coolant consumption, as well as with an increase in pressure in them. The water pressure drop indicates a violation of the system's tightness, and temperature differences - the presence of air in heating radiators.

Determination of the placement of traffic jam and its removal

How can you understand that there is air in the radiator? Usually, the presence of air indicates outside sounds, such as bouffaging, water flow. To ensure a full circulation of the coolant, it is necessary to remove this air. With full recent system, it is necessary to determine first the place of formation of traffic jams, tapping the hammer over heating devices. Where there is an air traffic jam, the sound will be more ringing and strong. Air is assembled, as a rule, in radiators installed on the upper floors.

Using that the air in the heating device is present, you should take a screwdriver or key and prepare water tank. Opening the thermostat to the maximum level, you need to open the valve of the crane of Maevsky and substitute the container. The appearance of light hissing will mean that the air comes out. The valve is kept open until water flows and only then closed.

Elimination of air traffic jams in the heating battery using the Maevsky crane installed on it: the valve opens with a special key or manually and kept open until water

It happens that after this procedure, the battery warms not long or not enough. Then it needs to be purged and rinsed, since the accumulation of garbage and rust can also cause air appearance.

If, after the air shutter, the battery is still badly heated, try to merge about a 200g of the coolant to make sure the air traffic jam is performed. If it did not help, but it is necessary to blow and rinse the radiator from possibly accumulated dirt

If after that there is no improvement, you need to check the level of filling the heating system. Air traffic jams can also be formed on pipe bends. Therefore, it is important in the installation process to observe the direction and the magnitude of the bias of laying pipelines. In places where the bias for any reason differs from the project, additionally install aircraft valves.

In aluminum radiators, air traffic jams are formed more intensively due to poor quality material. As a result of the aluminum reaction with the coolant, gases are formed, so they must be regularly removed from the system. In such situations, it is recommended to replace aluminum radiators to devices from better-quality materials with anti-corrosion coating and install air vent. In order for the heating of the rooms is normal, before filling in the heating system with water, it is necessary to take care of the removal of air that impede the normal movement of the coolant from it, and then in winter in your house will be warm and cozy.

How to lower the air from the battery if there is no crane Maevsky

Most often with the heating system in the house there are no problems. But sometimes suddenly in the house becomes cold or strange sounds arise in the heating radiator. What can it be? Unfortunately, in this case there is air in the heating system, which means that air is needed from there. Today you will learn how to do it without crane Maevsky.

Enforcement in the battery: what it is and how to determine

What is enforcement in the heating battery? Under this concept, air accumulation is meant, and most often in the upper part of the heating radiator. Such a situation becomes a problem and quite frequent for those who live in high-rise buildings on one of the last floors. The reasons for the occurrence of such trouble can be several:

Carrying out repair work on the site / in the neighboring floors. In case, in a residential square, work with heating pipes were carried out, the likelihood of a small air flow system was large.
There was a leakage of the coolant on some of the sites (which means immediate checking system to eliminate leakage).
Feature of the system of warm floors. The problem of the enforcement system is indeed a frequent pattern in the presence of a warm floor system, especially if it has a complicated scheme and many branches.

In water having a high temperature, air is contained and the more often the coolant is updated in the system, the higher the probability of a malfunction.
If the appearance of the air "traffic jam" coincides with the launch of the overall heating line - with a greater share of the probability, it is possible to say that it is the start of the system that caused recent.

Council. If you live in a private house, then, in principle, it is not necessary to get hard to worry about the enforcement of the system (if it is small), the fact is that in private heating systems most often the coolant changes extremely rarely, and it means that the air must be independently scribified within a few days.

Determine the presence of air "traffic jam" is simple enough. For example, if the water temperature in the battery has dropped sharply or the battery has become cold only partially, it may even start the bubble - all this is signs of delight.

Rest of air without crane Maevsky

On most home heating batteries, there is a special device that helps as easier to simplify the task of air boom - the crane of the Maevsky or automatic valve.

But here is the question: what to do, if such a device is simply missing on the battery? If you just like this picture before your eyes - most likely, cast iron batteries are installed in your house. On such batteries, a simple plug is often installed, which was spinled on the pack-covered panel. In addition, it was also filled with a layer of paints during the staining of heating batteries.

Remove it in order to access the heat carrier located in the system, it seems difficult. For this reason, the simplest way out of the situation can be considered an appeal to the neighbors from the last floor of the house (they will certainly have a crane of Maevsky on the battery). But if neighbors, for example, have left or you yourself are the tenant for the last floor and there is no crane? In this case, you will have to resort to the "Dedovsky" method of streaming air from the heating system.

So, you need to stock basic, bucket and plenty of rags. In addition, after all, after all, it's not to take this "barrier"), you will need an adjustable key to unscrew the plug and some kind of solvent for paint. Otherwise, you just can't move the plug with the "dead" point.

So, first apply to the place where the plug is installed, solvent and wait 15 minutes. After that, you carefully start moving the velocked key along the thread until the plug is fed. You will hear how the air starts to burst. When the sound drops (a sign of lack of air), be sure to turn the "Fumka" layer plug and insert it into place. If you wish, you can slightly paint the interface of the plug with the battery.

You learned about how quickly and quite simply can be copped with the task of moving the air from the radiator of heating in the absence of the crane of Maevsky. Good luck!

How to lower the air from the battery in the heating system, if there is no crane Maevsky

Sometimes strange sounds arise in the heating radiator. There is an air in the heating system. Tell me how to pull the air without crane Maevsky.

Special video instructions and training materials will help you to lower the air from the radiastore, how to pull the air from the heating radiator almost every year. Without this procedure, the owner, both apartments and private houses just freeze in its premises. At the beginning of the heating season, such problems appear as cold or noisy systems, and they may occur even in the case of perfectly performed installation. In order to not only reveal, but also to eliminate such problems, it is necessary to carry out preventive work to eliminate enforcement.

Signs of air accumulation: how to pull the air from the battery

To determine if your batteries have wondered.

This is evidenced by the following signs:

The return of heat has decreased noticeably (radiators that were previously hot, ceased to heat up);
You began to notice the presence of noise, cod, murmur and reduced pressure in the pipes;
If you have autonomous heating, then an increase in fuel consumption will be explicit;
The system stopped moving fluid, circulation is broken.

The presence of air in radiators threatens not only a decrease in the temperature indicator, but also more global problems. For example, batteries made of steel begin to oxidize, to be covered with rust and fail. Narrow places are styled and needed flushing or fully replaced. If your heating is individual, then the accumulated gas in the system can lead to the failure of the circulation pump, because in normal state the bearings are constantly in water. In case of trimming, the installation is subjected to dry friction, which causes excessive heating and the failure of the failure.

Why the system is delivered and how to delete the heating system

Before you know how to eliminate the cork from the system, you need to clarify the cause of its formation.

The most common factors are as follows:

Incorrect installation work;
Incorrect direction of direction or tilt
Pressure is low, which leads to the formation of emptiness;
Natural gas formation process in the water heating process;
The system was not correctly filled after installation;
It was broken tightness at the joints;
A warm floor system was not properly connected;
Inside radiators and pipes eat corrosion;
The coolant has too much speed;
Air intakes are in a faulty state.

It should be noted that in aluminum type radiators, which are installed in apartment buildings, air traffic jams are the most frequent problem. In this situation, it is wiser to establish bimetallic installations, cast-iron or steel. A temporary solution to the problem can be the installation of an automatic air vent.

With what and how to pull the air from the heating radiator

In order to control the system's gaspace both in the apartment and in a frequent house, use a manual or automatic air discharge valve. They should be stopped in more detail.

These include:

Automatic air valve;
Air separator;
Crane Maevsky.

Automatic air valve is able to release air independently, which accumulated in the radiator. It includes brass body, float, hinge lever and valve. In order not to have a leakage, the special cap will save the special cap, and the protection under the spring from entering outward pollution.

The system works on the following principle:

While the air is absent, the float holds the valve in a closed form;
In the process of accumulating gas, the float begins to fall and gradually open the valve;
Air accumulation leaves compartments, and the system comes to its original state.

It is important to note the fact that all automatic options are equipped with connectors that are suitable for screwdriver or eight-marginal keys. Thanks to this form, you can open the valve even in manual if you suddenly break the automatic mode.

As for the separator of the air, this system is a bit more complicated. The principle of its action lies in the absorption of air, turning it into bubbles and derivatives outward. Most often, separators are combined with sludge, which is able to catch an admixture of dirt, sand or rust. If we talk about the design, it is represented in the form of a metal cylinder, which includes the air vent and the valve at the bottom, which serves to reset outsided pollution. Inside such an installation there is a grid that creates a vortex flow.

The same method is used in the presence of a water circuit, which is connected to heating. The release in the plumbing is carried out as a blending. That is, through the whorler, you can produce the flow of air or water with impurities.

Maevsky's crane: how to pull the air

Maevsky's crane should pay special attention. This is a needle radiator unit, which includes a jar, screw and body in the form of a cone. All these details are hermetically adjacent to each other, which completely eliminates the flow of water. As for air, which can be in the radiator, it comes out through a small hole located on the side of the crane. This installation can be opened using a special key that always goes in the set, if there is no one, you can use a conventional screwdriver, and some models provide manual opening.

If we take into account the modern bimetallic installation, then the holes for the installation of cranes are already provided. The Maevsky crane itself should be installed in such a way that the tube for the air vent from the opposite side is in parallel to the floor.

If your batteries are made of cast iron, automatic type air vents are best fit here. They correspond to the characteristics of the design and composition of the material.

In order to remove the air with the Maevsky crane to withdraw the air.

Namely:

Prepare keys or screwdriver, liquid container and rag;
If your system includes a pump, it must be temporarily disabled;
The container will put under the crane and gently turn it counterclockwise;
From the crane will begin to descend the air, it may be included in itself dirt or rust;
We must wait until water flows from the crane, and block it.

If the water quality is not the best, then you need to install a few more additional cutting valves. They should be placed to the crane of Maevsky and protect it from possible blockages.

How to remove an air stop from the heating system in a private house

Get rid of the air traffic jam in the autonomous heating system of a private house more difficult.

To do this, you will need to do the following:

Determine the location of the plug. In her place will indicate the murmur noise, the cold area.
Promote up to the nearest valve. The crane must be slightly open and gradually strip air.
If this method did not give the result, you can try to raise the pressure and temperature of the heat carrier. In most cases, the cork begins to move and can be removed through the crane. The work should be done very carefully, since I have a chance to get a burn from steam or hot water.

If the joints are not installed in your system, you will have to merge all the liquid from the system and fill it over. In addition, the root floor becomes a warm floor, which is attached to radiators.

Thring a plug or simply drive out the extra accumulation of air in the heating system, a special device can help, it is called a slidder or a downset. It operates on the same principle as the trigger valves that help to expel, or completely remove the enforcement.

Removing gas education in batteries is a very important procedure. How to spend the system, pull the water with an air stopper, clean the radiators and restore the water supply stream you can learn video. Especially it will be useful to the owners of the boiler that they want to sell air in the system that brought.

Causes of air appearance in the system

On the threshold of winter, the beginning of the heating season is nearing ... Finally, the long-awaited day has finally come, when the house is warm and comfortable, but, unfortunately, the rooms are still cool: the batteries are hot, at the top - completely cold.

Wine all over an air traffic jam in the heating system.

The reasons for its appearance may be several:

in water there is a dissolved air - in the process of water heating, the air begins to stand out as bubbles. They rise to the top of the pipelines, accumulating there, thereby creating air traffic jams;
enpassing occurs during the repair of pipelines and subsequent assembly;
improper filling - the system must be filled slowly, removing air from distributors, radiators at the same time. It is necessary to act on the following principle: the more extensive and branched system, the slower it should be filled;
unsatisfactory tightness - not very large system flaws difficult to notice, for example, to flow on a connecting junction, since hot water evaporates quickly. That's through such looseness, the air is sucked into the heating system.

How to define vendors?

As is well known, extraneous sounds may appear in the heating system in the heating system (for example, bouffaging in the pipeline, flow of water).

The traffic point of the plug can be determined, gently catching up the pipes and heating appliances. Where the sound of the strike is obtained by the most voyage.And the air traffic jam was formed.

Ways to remove air from water heating systems

Since heating can be both natural and with forced circulation of the coolant, then the air in the heating system can be pulled in different ways.

For natural circulation systems (The upper wiring of pipes is considered) the aircraft can be removed through the expansion tank, which must be at the highest point relative to the entire system.

The feed pipe should be laid with a climb to Baku. If the layout is lower - the air removal should be provided in the same way as in the heating system with the circulation pump.

For circulation systems with forced circulation An air collector should be provided - in the highest point, which will be responsible for the release of the air.

The feed pipeline in this case is paired with the rise in the direction of the coolant, and the air bubbles, climbing the riser, are removed from the heating system through air cranes, which must be installed at the highest point.

In any case, the return pipelines should be laid with a certain slope - towards draining water to speed up the emptying of pipes during repair work.

IN closed type heating systems Automatic air vents are envisaged - they are installed at several points along the pipeline line, the air reset from which is made separately.

If the installation of the heating system and laying the pipes under the required slope is made correctly, then the bursting through "air" will be simple and not entail any problems.

I would like to note that the removal of air from pipes is accompanied by an increase in the flow rate of the coolant and increase the pressure in them. In case of recent heating batteries, there may be poor tightness of heating pipelines or an uneven temperature difference.

Very often in residential buildings equipped with an autonomous boiler with an open heating system, water reset can be carried out directly through the expansion tank: after emptying it is desirable to wait at least half an hour and only then open the "air" on the tank - the air will independently come out with the increase in water temperature in the system .

Where are the air vents?

The main ("critical") points of installation of air vents are:

Bend in the system of pipelines ("knee", turn ").
The highest marking of pipelines.

Varieties of air vent

The air ventures can be manual and automatic.

Manual

This includes a crane Maevsky, having a small size. The place of its installation is on the end of the heating device. The adjustment of the crane of Maevsky occurs simply - manually, the key is either a screwdriver.

Since the dimensions of the crane are small, then its performance is low, so such a "airier" can be used only for local removal of air traffic.

Automatic

These models, as a rule, do not need human presence. Automatic air vent consists of:

hull;
float;
rocker;
spool.

Its principle of operation is based on the displacement of gas when it is admitted to the device chamber.

Float mechanism moves in the chamber. If there is no air in the system, it is located at an extreme top point. The spool connects with a float with a rocker. The spool overlaps the air fitting until air falls into the system. The fixation of the spool occurs under the action of the spring.

Automatic aircraft with valve mounted vertically. The air fitting should be directed up. As a rule, the air vent is installed at the uppermost point of any system, as the gas (air) is lighter than water and rises up.

Mounted device simply. To do this, you will need a horn key. With its help, the air vent is screwed into the threaded connector using sealing means. You need to twist directly for the hexagon on the blade housing, otherwise you can damage the device.

During installation of automatic air vent air valve closed cap To avoid damage.

So that in the future it was convenient to operate the device, it is recommended to be installed after the shut-off valve. In this case, uninstall the air vent can, without merging the liquid from the system.

How to release air from the heating radiator with a crane of Maevsky?

When airing air from the radiator, you need to unscrew the valve with one hand, and the other to hold the rag so that the water does not hit the floor. First go hiss, and when water appears in the form of a small trickle or drops, depending on the pressure in the system, you need to spin the valve back.

No need to be afraid that you will flood the whole apartment, since the hole in the crane is quite small.

Unscrew the valve in most cases enough on one turn, no longer needed, since the flow of air and water is limited to the hole of the tap itself. And if you unscrew it at all, then there is a possibility that you are hard to screw it back due to the large water pressure. That is, the principle of work of the crane of Maevsky is quite simple.

Maevsky's automatic cranes are better not to put on old cast iron radiators when using the central heating system, since the water in it is most often dirty and when the tap hole is only 2 mm, it will often have to remove it and remind the sewing needle or pin for its normal functioning.

Maevsky's taps are most often installed either on the upper parts of heating radiators, simply speaking, batteries, opposite the upper attachment of the pipe or thermostat, as the air always strives for the highest point, or on the heated towel.

Maevsky crane is installed by screwing into the radiator cork. It is only necessary to choose the desired thread size of 1 inch, ¾ inch or ½ inches. In the absence of a hole under the crane, the cork must be replaced.

Take cranes with rubber or silicone gasket, but for better reliability you can also apply a linen winding or a special tape to seal the threaded connection.

When installing or replacing the crane, you need to hold the key to the cork itself, as it should be remembered that the left threads apply on all plugs and plugs of radiators.

As a consequence, screwing the air vent, you weaken the heating radiator cork and, on the contrary, when the air vent plugs the cork is tightened.

Problems of aluminum radiators

Aluminum even the highest quality heating devices can be reacted with a coolant with the subsequent release of hydrogen. The intensity of this process depends on the quality of the coolant (its level of pH), the heating temperature, as well as the presence in the heating system of individual parts and elements made of steel, the cause of the process of electrochemical corrosion of aluminum.

To protect against corrosion, the metal from the inside is covered by a layer of protective film, the action of which is weakening over time, and then completely stops. This means that when installing aluminum radiators, a hydrogen isolation process capable of forging air traffic jams And block the movement of the coolant, is inevitable.

It's all about time: the appearance of hydrogen can begin literally from the first days of the operation of the heating device, and may be "to refine" for several years, or even decades.

The danger of aluminum radiators is also in the fact that the process of isolateding hydrogen can go at high speed at which the gas does not have time to rise up and forms high pressure zones capable of completely outputting the heating system.

Pipes and radiators are bursting and recovery are not subject to.

To remove air traffic jams from single-tube heating systems, as well as from heating systems with aluminum radiators, air vents are used in various designs, which are installed in the place of the most likely formation of air traffic jams.

How to remove the air stopper from the aluminum radiator heating?

Today, radiators most often change one simple typical scheme.

Two cranes are installed on the radiators, and the jumper is mounted in front of them or some-bypass is called it - bypass. By the way, the crane is not recommended for the jumper. If it is installed and not to have the concepts, how the heating system works, you can regularly overlap the circulation of water in the pipes on all floors of your home.

For these actions, it is possible to vaguely with local plumbers from its management company. Instead of installing the crane, the jumper make the pipe smaller diameter than the main pipes suitable to the radiator. Thus, the main flux of hot water passes through the battery, as heating as possible to your room.

In those cases, when it becomes hot in the room, the radiator can be turned off, overlapping any (upper or lower) the faucet thereby stopping the circulation of water in it. You can overlap and both crawl immediately, nothing terrible happens, but it's more often when the radiator wants to remove.

And how do the air descend from the radiator? The procedure is quite simple, for this there is a crane Maevsky. A small "pimple" located on top of the radiator from the opposite side of the incoming pipes. Included to the air crane there is a small plastic key. If there is no special key, you can use an ordinary scope.

How to understand what you need to lower the air and how often do it?

Determine, there is air in radiators or not very simple, during the heating season if you have noticed that half of the radiator warms up, and the half is cold, it means that there is air.

Most often, delighting occurs after shutdown in the heating house, for repair work.

Procedure for income radiator This: overlaps the upper shut-off valve on the radiator, the lower open. Any container is substituted to the spawn of the water of the water, for example, and the crane-maevsky itself opens.

We wait until the spout does not flow the water with a smooth jet without air impurities. Flowed? Sweep a small amount of water, it may be possible to leave the residues of the air and you can close. How do you finish do not forget to open the crane on the battery.

What if not helped?

There are situations when even after the air is descending, there are no necessary heating in the battery. Or the radiator warms, but not long. In this case, the batteries need to rinse or blow.

If the heating system installed autonomicallyYou need to check its full filling. If water acts as a heat carrier, it is quite quickly exposed to expansion. When the temperature decreases, the water may not be enough.

Often in homes that have an autonomous heating system have to be lowered through the expansion tank. It is always located at the highest point of the heating system. But before dragging water, you need to open the valves and turn off the house from heating.

Next, you need to wait half an hour, and only then you can open the crane on the expansion tank. Water runs you will hear on characteristic noise. Usually, the air traffic jam comes out by raising the temperature. If its outlet is hampered, bring water in the heating system to a boil. So the air will be released.

We descend the air from the battery - what you need to prepare

Before performing the procedure, prepare everything you need:

radiator key. Sale in a business store. It must be suitable for the size of the battery. You can examine your tool kit. Take from the set a small key of the appropriate size, a wrench or other tool. To lower the air from modern radiators, a regular screwdriver is suitable;
large wide pelvis or bucket. In the container you will drain water;
rags. Estate them on the floor near the radiator, so as not to flood the neighbors, you never know what happens.

Before lowing the air, let's move the hammer on the radiator. If you hear in some place too ringing sound - the plug is here.

We descend from the battery with the crane of Maevsky air

The crane of Maevsky is located on the battery at the top. On some models there is a plastic handle, to open the crane, the tools will not be required. Before lowing the air in the radiator with a crane of Maevsky, do not block the entire riser of the heating system and do not wait until the heat carrier cools. This work is useless and reduces the effectiveness of the fight against the plug, as the pressure will fall in the system.

Procedure:

substitut under the crane of the pelvis for collecting the coolant;
place the rags on the air vent. The liquid is absorbed into the rag and starts to drain smoothly;
smoothly unscrew the crane with the key or behind the plastic handle. Hear whistle or hissing, it turns out;
wait until a uniform water stream starts to flow. This indicates that you punched an air stopper. This will take from 5 to 7 minutes. Experts recommend to merge up to two buckets of water;
close the valve.

We descend the air from the battery with the automatic air vent

This device works offline and is mounted on the battery horizontally or vertically. Removing air traffic jams occurs without your participation. A special float is installed on the air. It hermetically covers the faucet if there is enough water in the system. As soon as the air accumulates - the float is lowered, the hole and gas opens. But the device has a flaw. He is very susceptible to the quality of water. If there is impurities in the coolant - the mechanism breaks down. Therefore, use filters and change the sealing ring periodically. Also regularly clean the valve, otherwise there will be water from the battery. If you take care of the device - you don't have to fight with air traffic jams yourself.

We descend the air from the old battery with a plug

On old cast iron batteries, a plug usually cost if you did not change them to the cranes of Maevsky. The work is to be difficult, the plugs are fixed by packles and paint. First you need to overlap the heating system. Prepare a separate or gas key for work. Next, your actions are as follows:

put the rag on the floor;
under the crane substitute the bucket;
slowly and carefully unscrew the key plug. If it does not work - apply a special lubricant on a thread or a little solvent;
after the outlet of the air and draining the water, wrap the thread of the plug of the Lena or Foney ribbon and tighten it. It will relieve possible water flow.

We descend the air from the battery in a private house

In the heating system of the private house, the air descent is carried out using the expansion tank. It is located at the highest heating point. After the descent of the water, wait a little and on the tank to unscrew the crane. The plug will be released itself, the temperature is increased. If there is no positive result - you bring water to boil in the circuit and the air will be released.

Timely removal of air traffic jams from batteries is setting up the efficiency of the heating system. After the correct actions in your apartment will noticeably warm. Work is simple, but if difficulties arose - call specialists.

sovetclub.ru.

What is dangerous air traffic jam in the radiator?

If a delometry appeared in the battery, there will be nothing good. Excess air is an obstacle for the normal functioning of the system. And may also cause corrosion formation on the walls of the radiator.

If the circuit pump is installed in the circuit, the air stop can disrupt its operation. When the system functions correctly, the sliding bearings on the shaft of the pump unit are constantly in the water. And if there is browning, the effect of "dry friction" occurs, which adversely affects the sliding rings, and can output the shaft. Therefore, it is important to know how to drive out the air from the home heating system. The measures taken on time will help prevent damage to the heat supply network.

How to understand that there is an air traffic jam in the battery?

Before releaseing the air from the heating system, you need to figure out why it is formed in the circuit and how to understand that there is an air traffic jam in the radiator. Most often, the excess air accumulates as a result of improperly filling the system with water. The reason may be the result of errors allowed during installation. Low pressure in the circuit, the low-quality coolant with the presence of dissolved oxygen can also lead to delighting.

The air traffic can occur under such circumstances:

The excess air has accumulated in the system, such signs can be evidenced: hissing and bubble sounds in the battery, the quality of heating is reduced, heating becomes uneven, in the air sections, the radiator can be cold.

Such situations are frequent. Surely every owner of the apartment or a private house faced a similar problem. Therefore, it is important to understand how to remove the air from the home heating system, the more it is not difficult to do it with your own hands. It should be noted that most often the air cork is formed in the batteries that are installed on the upper floors of the house.

In this case, how much does not blend the excess air, it will be formed again. And the reason lies in the fact that the material from which the battery is made is promoting the formation of gases. Exit from the situation is only one - buy a new radiator. Therefore, it is better to immediately acquire heating devices from conscientious manufacturers.

How to remove excess air from the battery?

Before you pull the air from the heating system, you need to look good in the peculiarities of this procedure and prepare all the necessary tools and materials. Consider how to remove air from the heating system in more detail. For such a job, you will need a special key with which you can open the air valve on the radiator.

The best radiator key is suitable. It is sold at any economic store. If a modern battery is installed, you can take a simple screwdriver. It is necessary to prepare the container into which the coolant will merge. And also have a couple of rags near the emergence of unforeseen situations.

Algorithm of actions, how to correct air from the heating system, is given below:

In addition to the cranes of Maevsky, both the automated air vents for the heating systems are often used, which are watered independently. Such automatic units are compact and reliable. But at the same time it is necessary to be extremely careful. After all, the valve is running unattended. And the slightest violation in the process can cause the attic of the attic or the riser.

Some nuances

There are situations where the wizards when installing the heat supply system do not install special valves for excess air. Consider how to release air from the heating battery in this case. To work, you will need a separate or gas key. With it, you need to unscrew the plug. Do it need it very slowly. Sometimes the plug is not unscrewed. Most often it happens if the battery is iron. At the same time, it is necessary to put a special lubricant on the thread and after some time to repeat the attempt again.

When the plug is unscrewed, the same algorithm of actions is performed as with a conventional crane. When the plug is tightened into place, you must not forget to wind on the thread or FUM tape, or flax. This will avoid the leakage and give tightness to the connection.

If the air has accumulated in the private home heating system, the water descent will have to do with the expansion tank.

This container is always located at the highest point of the heating system. When the water is descended, you need to wait a bit, and then unscrew the tap on the expansion tank. Usually, when the battery increases the battery, the plug leaves independently. If such actions turned out to be unsolved, then water should be brought to a boil. In this case, the plug will necessarily come out.

How often do you need to lower the air?

Knowing how to keep air from the heating system, you can prevent many problems. But how often do you need to pursue a similar procedure for prevention? As a rule, it is necessary to do it at the beginning of the heating season. Two times quite enough (for the first time for checking, the second to control). Of course, if there are defects in the system either it is faulty, then the number of descents can be greater.

If aluminum radiators are installed in the apartment, then before running the system, it is necessary to make water descent. This will help increase battery life at times.

Preventive measures

Of course, to know how to blow the battery of heating is important and necessary. But it is better that the system enjoying is happening as less as possible. It is better to prevent this situation and install the air vent.

At the moment, air collectors of heating systems can be two types: manual (presented by the Maevsky crane) and float (or automatic). Each of the above types can be installed in various places in which there is a risk of deliverance. Maevsky crane configuration is traditional. Avtovo-aircraft can have an angular or direct execution.

In order not to break the head regarding how to delete the heating system, it is mandatory to install an air vent on each battery.

Manual type air vent

Manual type air drains are usually mounted with the end side of the radiator. With their help, you can easily guard excess air. It is enough to have only a special key. The performance of such devices is small. Therefore, such an air collector for the heating system is installed only for use at home.

Automatic type of air vent

As for automatic type air vents, they function offline. Unscrew, you do not need to open anything. The device does everything alone. Mounted them strictly in a horizontal or vertical position. But it must be said that such an air shuttering valve from the heating system has one drawback - high sensitivity to pollution of different character. Therefore, it will be necessary to additionally install a filter that will clean the device from mechanical pollution.

Important! If air is formed in the heating system, it should be found out the reason for this situation. Especially if there were no such problems. It is important not to just remove the air stop, but take all the measures so that it does not appear again. Therefore, you need to check the device for tightness. Perhaps somewhere should be swapped or tighten the bolts, to better close the joints. And perhaps the air vent was installed incorrectly or automatic air separator for heating failed.

The heating system needs constant control. It is often in it there are air traffic jams that violate its functioning and can cause an emergency. To avoid this, you need to know the ways to help lower the air from the batteries. Due to this, it is possible to improve the quality of room heating and eliminate unpleasant sounds that often appear in such cases.

Show all

Causes of importance

Although the heating system is sealed, air is often accumulated in it. Especially often this problem is observed in apartment and private houses in the first days of the heating season. The main causes provoking it are considered the following:

In some cases, deliberation is associated with water composition. To resolve the problem, you must install a special filter. In private houses are often used plastic pipesTherefore, the appearance of an air traffic can indicate use when installing low-quality barrier valves.

Signs and danger of air traffic jams

Some argue that it is not necessary to spend the battery in an apartment or a private house before the start of the heating season, but this opinion is erroneously. If you make a heat outflow of the radiator, in which air bubbles are present, you can see that their places of cluster have a low temperature. They are cold on the touch.

That is why when the system is reinstating the system, the efficiency of heating falls noticeably. Even when the outdoor, the temperature does not fall below -3 ° C, it will be cool indoors. In a private house, a low heat transfer associated with the presence of air in radiators or pipes is also observed when the heating boiler is also observed.

The owner of the house when trying to run the operation of the heating system can hear the murmur and bullshit in batteries, which indicates the need to carry out the air masses. In some cases, sounds are more sharp and resemble a knock on the metal with a wooden stick. It is urgent to fix it, since it is possible to disrupt the functioning of the boiler. If there are no signs, but radiators are still heated unevenly, you can knock on them in different places with a metal object. In the area of \u200b\u200baccumulation of air masses, the sound is more ringing and high.

With a large amount of air, the pump that helps fill the heating system with water, simply cannot push it into the pipes. At the same time there is a sharper and loud knock. This often leads to the failure of not only the pump, but also the boiler, since the latter overheats due to the lack of normal circulation of the coolant.

Crane on the battery - for moving air and draining water.

In addition, the metal of batteries and pipes with long-term contact with air begins to think, areas of corrosion appear, which gradually remove the device. It should also be borne in mind that the constant and uneven heating of the material harms the system and provoke emergencies. That is why it is recommended to lower the air from heating radiators when the first signs of traffic jams appear.

Ways to solve the problem

Today there are several ways to help release air from the heating battery. In apartments and private houses, such a process may differ. As a rule, this is due to the principle of operation of the system in the house, and in apartment buildings, centralized heating functions equally.

To work, you will need a special adjustable key. If the radiator of a new generation (bimetallic or aluminum), then a regular screwdriver is suitable. It is worth keeping enough sufficient rags, as well as a wide pelvis, as water flowing is inevitable. After that, you can proceed to the extension of the air traffic jam using one of the popular methods.

Crane Maevsky

In apartments often use Maevsky's crane. It is a nice needle-type valve located on the battery from above. Models are produced with a plastic handle without it. In the first case, the tools will not be needed. When working with a crane, there is no need to overlap the entire riser and wait for the cooler cooler. This will lead to a reduction in operating pressure. To descend the air, you must perform the following manipulations:

Next, you need to close the crane. If the manipulation was carried out in the apartment, the system is independently filled with the coolant. In a private house, it is necessary to fill it again in the case when the pump is turned on manually.

Automatic air vent

Such a system is called the float, it is completely automatic and does not require human intervention. The air vent is mounted on the radiator in a horizontal or vertical position, reacts to the amount of coolant and when the air collects is accumulated. With a decrease in the amount of water, it is lowered and the valve producing a plug automatically opens. It is very convenient and excludes various emergency situations.

# 86. How to release air from the heating radiator?

However, the device has a disadvantage - it is very sensitive to the chemical composition of coolants in the presence of a large number of harmful impurities quickly fails. Special water filters and regular replacement of the sealing ring will be avoided.

The automatic air vent is considered an ideal option for a private house, because it does not require a re-launch of the system and draining a large amount of water. With proper operation, it may stop long.

Battery plug

Previous ways are relevant, provided that modern radiators are installed in the apartment or house. However, in many buildings, cast iron batteries are working. Correct the air of them is problematic due to the lack of crane Maevsky. Instead, there are special plugs fixed with paint and packles on radiators. In order to keep air, you must perform the following actions:

Screw the plug is needed carefully, but firmly. It is recommended to additionally wrap the thread with a special ribbon that will help to avoid leakage of the coolant. Only after fixing is allowed to open the crane that feeds the water into the system again. This method is rarely used in homes and requires certain skills. In case of their absence, it is better to contact a specialist.

In a private house

In many houses, Maevsky is installed, so when replanting the system, you can use the same method as in an apartment building. However, usually there are no such devices, which is why the single way will be the descent through the expansion tank.

Such a device is a mandatory element of any heating system in the house. It can be open and closed. The first option is simpler in operation, and the system enclosure typically means a decrease in the water level in the container. To eliminate the problem, it is enough to fill the missing amount of fluid.

If the heating system has a closed tank, the only solution to the problem will be the release of the air through radiators. Before that, it is recommended to try to fully fill the system so that at least 10 liters of water resulted from the control tube coming out of the tank.

After that, you need to start the system again. If the problem persists, it is recommended to lower the air masses from the battery, following the general recommendations. It is worth noting that the heating systems of the old sample air in radiators may appear with the intensive operation of the heating boiler.

Especially often it is observed when installing solid fuel models without a built-in thermostat. Water heats up excessively, starts to pour out and pour out through the control tube of the expansion tank. As a result, it will be empty and in the presence of cracks that disturb the tightness, air masses begins to the system. You can lower the air to any of the listed methods, but before that it is necessary to eliminate the holes or cracks. Otherwise, the descent will have to repeat regularly.

How to make air from the cooling system Audi 80. [@ 2015]

Methods of prevention

In order to constantly not to lower the air from the radiators, it is necessary when you start the heating system to perform all actions correctly. Open type of system involves independent filling of pipes with the coolant. To do this, open all the valves, providing an unimpeded movement of water.

The pressure should not be too big. It is recommended to pay attention to the drain valve, which must be closed when the radiators is filling. If a closed type heating system, the algorithm is somewhat different. The first step will be the closure of all valves, except that it starts water. Next, you should connect the pump that provides stable pressure in the pipes. The next step will be filling the system by the coolant. Only then follows the air from radiators using the crane of Maevsky.

Air in the battery is a common problem in homes and apartmentsImpretting the normal heating of the room. When implementing the recommendations of specialists, an ordinary person can cope with her without professional skills.

Causes of air appearance in batteries

With the beginning of the heating season, some residents of apartment buildings and owners of their own cottages are asked to the problem: how to release air from the heating battery?

How to release air from the battery

The need for this arises due to uneven heating of premises. After the start of the heating season, it becomes noticeable that some batteries warm well, and some remain coldly or half. Cold radiators and noises in them - signs of formation of air traffic jams, the causes of which are:

the lack of proper pressure in the heating system, which in itself leads to incorrect work. The pressure decreases when leakage of the coolant through poorly sealed seams;
issue of low-quality radiators, non-compliance with standards in their manufacture;
production of poor-quality repair work - non-compliance with the direction of the liner of the pipeline highways;
incorrect filling of the water heating system - the filling should be carried out with simultaneous air descent, the descent can be carried out only by slow pace;
low water quality in the heating system - too rigid water does not allow the system to work correctly, the optimal rigidity is 5-7 mg / eq / l.

Cold heating equipment in this case Polbie, the air traffic jams the threat of the entire heating system as a whole. Metal parts of the system rust and cease to perform their basic functions, which can entail additional spending in the form of replacement of the entire system.

Rust on the heating battery

Unpleasant moments are extra noises in the premises. This is usually the sound of current water, noise and crackle, which distract and interfere with rest and work. Therefore, the problem of the correct release of air from the battery remains relevant. For independent work, you need to know the nuances of the correct manipulation with heating devices for water descent.

How to release air from batteries

In homes and apartments, old heating systems are adjacent to modern, somewhere installed batteries equipped with aircraft systems, and in other places there are still cast-iron structures without them. Therefore, to understand how to release air from the batteries of a particular design, sometimes it seems to be a difficult task. As a rule, we consider several ways to conduct preventive work.

In the heating system with a natural circulation, in which the pipe wiring is in the upper part of the system, the air stopper is removed through the accumulative tank, which is also at the highest point. Such systems, as less stable, are departed into the background. Their place is occupied by systems with forced circulation, in which air vents are needed. They are installed on aluminum and bimetallic heating devices. This is correct due to the fact that when these materials contact these materials, hydrogen will necessarily be allocated to the coolant, which should be removed.

Old Sample Heating Battery

Manual air vent or cranes of Maevsky

Invented Plumbing Crane on the name Roeev, and another more deft master, by the name Maevsky, patented the invention. In the usual way to merge water through large holes in radiators was not economical for boilers, since citizens used hot water from radiators for personal needs. For example, for laundry laundry or car washing.

Maevsky's crane is a mechanical unit, which is a 1/2 or 3/4-inch threader with a tiny hole in the middle and a rubber sealing ring. Sometimes it is also called the needle valve air vent. It is attached to the radiator with the help of a hood (sleeve with outdoor thread). The valve is installed on the top of the radiator or heated towel rail.

Maevsky's crane is installed on the top of the radiator

To start producing air from the heating system, unscrew the cone-shaped screw for the tap counterclockwise and wait for light hissing and droplets or water pips - the air went. If the hiss is over, this does not mean that the process is completed. It is better to wait some time, and then spin the crane.

Air descent from heating radiator.

Council. You do not need to unscrew the valve, since the water pressure may not allow it to be twisted later. When conducting manipulations, it is important not to forget to put a rag next to the battery. It will not be superfluous to pay attention to the fact that the hole is not directed to the walls, as the threat of deterioration of the room decoration will appear.

Price of crane Maevsky 60-100 rubles. Some firms offer models stylized under the old days, their price reaches 1200 rubles.

Maevsky's crane stylized for old

Automatic air vent

This is a metal unit securing on the radiator, which is designed to automatically remove air without human participation. Inside are float and needle valve. These two mechanisms create the balance of the air vent. In working condition, the hull is filled with water, the float is raised, the valve is closed. The resulting air gradually enters the device, the float is lowered under its effect and opens the valve that the allowance will be outward. These devices are usually installed at the highest points of the heating system, where its largest amount accumulates.

These units can be straight or angular, depending on the configuration of the batteries. It is important that the outlet should always be directed upwards.

Automatic angular air vent

Automatic air vent is installed in two ways.

Direct installation in the thread.
Installation through a shut-off valve. This valve allows you to shoot air vents without disconnecting the system. Remove them for periodic cleaning, as in polluted impurities, it stops working properly.

To avoid problems when installing this mechanism, a number of rules comply. You can only unscrew it with a wrench only, since when using the divorce, you can not calculate the effort, and it will crack. For the aircraft body, during the work, it is impossible to stay - you can break.

Automatic air vent on the battery

The price of an automatic unit from 300 to 500 rubles, which is significantly more expensive than its mechanical analogues. Famous firms that produce air vent - Danfoss and Wind.

How to release the air from the cast-iron battery

To carry out manipulations to remove excess air from cast-iron heating devices of the old sample in apartment buildings, plumbers from Jeep are invited, as this rule is regulated by the Decree of the Ministry of State Construction of September 27, 2003. In fact, plumbers are eliminated from these works, providing the right to the owners to solve problems with heating.

In private cottages, as a rule, this work has to be performed by the residents themselves. Some craftsmen are installed on holes in cast-iron batteries. An ordinary faucet is that, undoubtedly spoils the type of dwelling, but simplifies the process of air descent. To release the air from the cast-iron battery correctly, you need to know a certain sequence of actions.

Mounting hose to the radiator hole

In a private cottage, the boiler is definitely disconnected. If still work is decided to produce yourself in the apartment, you need to turn off the distribution valve on the riser. Next you need to go to the installation of the hose to the radiator opening. The hose should be long, reach the nearest convenient drain into the sewer or to the street.

Council. During the release of water, you need to put a bowl or a bucket with water under the battery and stock rags, as the water flows out of the battery.

Then unscrew the plug. It happens not easy to do, because cast-iron batteries usually paint oil paint, and it solidifies around the plug. Sometimes there is also a pass to the connecting parts, which also does not contribute to the light unscrewing plugs. To facilitate the work, they apply a special lubricant on the thread, which simplifies the revealing process.

Works are produced using an adjustable wrench.

Council. If you immediately unscrew the cap on the cast-iron battery, it is not possible, the lubricant does not help, the kerosene will help dissolve the paint, it is applied to the joints and waiting for 10-20 minutes.

After all the necessary works are carried out, it is necessary to wind the fum-ribbon plug (thin transparent seal) and again attach it.

At the end of the work, install the plug in place

Do I need to produce air from the battery, solve the owners of houses and apartments. But if there is a desire to live in comfortable conditions, not freezing due to incorrectly working heating, it is better to learn to produce air from the heating battery itself. Moreover, when knowledge of the sequence of actions, it will not be a challenge!

How to release air from the heating battery - specialist advice

Causes of air in batteries with the beginning of the heating season, some tenants of apartment buildings and owners of their own cottages are asked: how to release air from the heating battery?

And if there is no shrink valve?

It is necessary to stock up with a gas or adjustable key, with which you can unscrew the plug.

The main problem is that usually the plug prevents the thick layer of paint and hardened pacle. It is possible to solve it using kerosene or lubricant for threads. We apply it to the connection and wait for 15-20 minutes.
Gently turn the cap and descend the air in the same way as in the case of Maevsky's crane. Do not forget about the container for water and about a rag that prevents splashing.
When you twist the plugs, you should not forget to apply the seal on the thread, for example, FUM tape to eliminate the leakage of the battery in the future.

To facilitate this difficult task, many owners put a regular crane in the past in the past. He did not add aesthetics, but the procedure facilitated significantly.

To ensure a guarantee, it is enough to carry out an excess air whipping procedure for all batteries twice. After that, the heating system will function normally.

In the water in small quantities is dissolved oxygen.

However, over time, it can lead to great difficulties in the heating system.

And if you have at least one radiator in your apartment (or home), you must know how to pull the air from the heating battery. And you can do without a call to the wizard!

Enforcement, or an air plug - this accumulation of air at the top of the heating device (or pipeline).

In apartment buildings, the inhabitants of the last floors suffer especially from the problem.

The causes of convulsion can be several. We list the main:

Repair works (if manipulations were made with the pipeline, it leads to ingestion of the air system).
In urban apartments, it is difficult to put in the work of the Highway without traffic jams, because ideally, the system should be filled with water very slowly, with simultaneous blending.
Somewhere leakage (even a small leak on the junction should be immediately eliminated).
Difficulties often occur with the warm floors, if its branches are laid not strictly horizontally and at different heights.
In any water, with an increase in temperature, oxygen is released. In private houses over time, all air leaves, and if the coolant does not change, you can forget about the problem. But in the central heating of portions of the liquid is updated constantly.

If it is not at all possible to do everything with your own hands, you can leave a request to the company serving the house to send the masters.

But the work of the system usually takes two weeks, so it is not necessary to hurry up with complaints.

How to determine it?

Detect the plug easily, she will give themselves to know:

Batteries can start bullshit;
The temperature in the rooms will decrease without visible reasons;
Part of the radiator will warm up, while the other area will remain almost cold.

Lightly knock the metal object at the top of the radiator, and then compare the sound from the knock at the bottom of the device. Where a plug appeared, the sound will be more ringing, high.

What can heating enforcement?

The phenomenon paralyzes the operation of the system - the circulation is disturbed, which leads to overheating of individual sections of the heating system and insufficient warming of others.

Because of the long-term contact with oxygen, many metals are covered with a scale, subjected to destruction. Especially sensitive to the launch of the heating system aluminum radiators.

In private houses with forced circulation, the air is in contact with the circulation pump. The device's life is reduced.

How to lower the air from the battery

In the gravitational system of the private house, all bubbles themselves go through the expansion tank located at the top point.

In urban apartments, an air vent is installed on each radiator:

Manual (crane Maevsky).
Automatic valve.

Depending on what is established, the work technology will change.

Aluminum, bimetallic or cast iron

Aluminum - Not the most suitable material for heating. It actively enters chemical reactions and highlights hydrogen. But thanks to its humble price and good thermal conductivity, it is often used. To combat aluminum flaws, it is covered from the inside with a layer of special film. But over time, it ceases to act, and hydrogen begins to stand out inevitably.

Bimetallic radiators - Another invention, improving the quality of heating devices. Where contact with the coolant occurs, another metal is used here. And fins are made of aluminum.

If a thermostat is installed on the battery, it is necessary to simply periodically open and wait for the air. The process of blending air from bimetallic batteries does not differ from work with an aluminum radiator.
