Connecting heating radiators

During the construction of the house or just when overhaul Private estates or apartments Installing heating radiators should be made after such elements such as doors and windows are already installed. At the same time, you must determine in advance what kind of connection of heating radiators will be used, and besides, of course, to prepare necessary materials and tools.

How to connect the heating battery? The process of installing the radiator itself does not take a lot of time and effort. First of all, you need to install battery mounts. Their quantity and location directly depends on the number of radiator sections. Next - we bring the pipes, install the radiator itself and connect everything. Consider on the example how to connect the heating radiator with polypropylene pipes.

Options for heating systems

The most common and in demand are one-tube and two-pipe heating systems. Consider each of them more attentively and proper connection Heating batteries in each case.

A single-tube heating system is used today mainly for multi-storey houses.

The hot heat carrier spreads through the pipes from top to bottom, evenly distributed over all heating devices. Such a system is mounted quite easily, requires a relatively small amount of materials. But at the same time, she has a number of flaws:

• there is no possibility to adjust the degree of heating of individual radiators;
• on the lower floors, the battery temperature can be significantly lower than on the upper, since the coolant reaches them already cooled;
• in the event of a breakdown on any floor, the entire riser is turned off;
• it is enough difficult to disconnect from the system to install autonomous heating.

The two-pipe heating system is most often used to create heating in private homes, cottages. It implies connecting to the radiator at once of two pipes: one to the battery there is a hot heat carrier, and the outflow of already cooled water is performed. It is important to take into account - all radiators in two-pipe system Connected only in parallel.

The two-pipe heating system has several weighty advantages. First of all, the temperature of all radiators will always be equal, regardless of how far from the boiler they are installed.

In addition, with this type of system, it is possible to adjust the degree of heating of each individual radiator - this allows you to create the most comfortable temperature in each room.

The heating system of this type includes the following elements:

• radiator with valve at the top and plug in the bottom;
• radiator corks;
• valve with thermostat;
• bypass;
• shank;
• stopcock;
• couplings and locknuts;
• heating pipes (metal, polypropylene).

It should be noted that the same set of components, with the exception of the valve with the thermostat and bypass, is suitable for mounting one-tube heating system.

Types of connecting pipes and radiators

The connection of heating batteries happens:

• side - Such a battery connection to the heating system is the most common. With this type of connection, the pipe with a hot heat carrier is supplied to the upper nozzle, and the reverse tube is connected to the bottom. That is, both pipes are located one side of the radiator. Such a connection of heating batteries is the most productive - with it there is a smallest heat loss. However, it is not necessary to use such an attachment of heating radiators, the number of sections of which are more than 15.
• diagonal connection Heating batteries - applied to sufficiently long batteries. With this type, the pipe with a hot heat carrier is connected to the top nozzle of the radiator on one side, and the pipe outflow of the cooled coolant is to the lower nozzle on the other side. Such a connection of the heating radiator allows the coolant to spread across the radiator as evenly possible. It is important to take into account - if you choose a diagonal connection of heating radiators among themselves, but in this case hot water It is carried out through the lower nozzle, and the outflow - through the upper, the efficiency of the system will decrease by about 10%.
• lower connection Heating radiators. Used only when heating pipes are hidden under the floor. KPD radiatorsConnected in this way is about 10% lower than those that are connected by the side method.

Types of radiators for strapping

Before you start creating a heating system and before connecting the heating batteries, you need to determine which types of radiators you want to use. Today exists great amount species of batteries. They may vary by:

• material;
• the principle of how to connect the heating battery;
• machine attachment to the wall.

Today, the most common types of radiators are the most common:

• - are a relatively thin panel of flat steel plates. How to connect the heating radiator of this type? The radiators of this type are connected by the side or in the lower way.

Steel panel batteries

• sectional radiators. Lightweight sectional model made of aluminum (there are also bimetallic radiators this type). How to connect the heating batteries in this case? You can connect such batteries by several sections or one. For such radiators, it is best to use polypropylene pipes, the connection type is lateral.

On the connection of the bimetal in the article: connecting bimetallic heating radiators.

It is noteworthy that recently in apartments with central heating increasingly installing bimetallic batteriesBy refusing cast iron. The reason for such a change is caused by a number of reasons. Primarily, cast iron radiators are heavier and cumbersome. In addition, due to the poor-quality water used as a heat carrier of the heating system, a precipitate appears quite quickly in such radiators, sand and rust appears - and these factors largely contribute to the decrease in radiators heat transfer. With bimetallic radiators there are no such problems.

For a private house you can choose panel radiators. They can be both aluminum and steel - it all depends on the desire of the customer.

The main thing is to comply with all the rules when installing. It is important to remember - if you are laid copper pipelineThe steel, and aluminum radiators can be connected to it. And in case the pipeline is ordinary pipes - It is allowed to install only aluminum batteries.

What is needed to connect radiators

Creating a heating system is a rather complicated process. Meanwhile, observing all the rules and a clear sequence of work, a beginner can cope with it. How to connect the heating battery correctly? The main thing is attention. For high-quality mount And some components are needed to connect radiators. In particular:

• adapters with right and left thread (Fortors);
• tools for high-quality screwing adapters;
• plugs, manual air vent, key for air booming, adapters;
• shut-off reinforcement ball Valves, valves;
• pipes.

Polypropylene pipes - Principle of implementation

Recently, polypropylene pipes are becoming increasingly popular. Of course, the correct connection of heating radiators and the strapping can be performed by any other pipes, but most professionals are recommended to still stop their choice on these.

For the strapping, the rational only use polypropylene angular ball valves - they are much easier to install, and their cost is relatively small.

The blockage of polypropylene pipes is performed as follows:

• in the multiflex connecting with any output, the coupling with a cape nut is inserted;
• through pre-attached brackets on the wall, pipes are fixed. It is important that they do not touch the walls, and were 2-3 cm from its surface.

The advantage of polypropylene pipes is that they can be laid in the wall itself, and the edge of the pipe needed to perform the strapping is removed in the immediate vicinity of the radiator. Fasteners for fixing batteries can be used in a variety of. Most often, professionals for this purpose use a pin compound, locking on the wall surface. If you want to suspend radiators - use ordinary brackets for this. Small refinement - panel batteries (mainly) are sold complete with fasteners. But for sectional radiators, the mount must be purchased separately

We already practically know how to connect the heating radiator. Connection of cranes is performed as follows:

• initially, the crane must be disassembled;
• the radiator screws up a fitting with a cape nut;
• using a special key, tighten the nut.

For high-quality execution, such a simple, and at the same time, a fairly important action will need to use a special key - without it you cannot normally tighten the "American".

In addition to this key, during installation and strapping of radiators, as well as while connecting two heating batteries, you will also need:

• seals;
• a set of keys;
• tow;
• threaded paste;
• thread threads.

FEATURES OF RADIATOR MANDATE

When installed heating radiators And while connecting the heating radiator, the requirements indicated in SNiP should be clearly followed. In particular, this refers to the maintenance of the required distance between the radiator and the wall, floor and windowsill:

• the distance from the top of the radiator to the windowsill should be at least 10 cm. If the specified gap will be lower, it may make it difficult heat flux - Thus, the room will warm up worse;
• the distance from the bottom of the radiator to the floor should be at least 12 cm. If it is less - there is a risk of a significant increase in temperature difference on different height premises;
• the distance from the rear wall of the radiator to the wall should be at least 2 cm. In otherwiseThe radiator heat transfer will be disturbed.

It is also important to consider the fact that the installation method and how to properly connect heating radiators also affects the quality of the heating of the room. So, options for installing radiators are possible:

• in open video Under the windowson maximum efficiency heating systems - 96% -97%;
• in open form in niche - efficiency just below - 93%;
• in partially closed form - there is a decrease in efficiency up to 88%;
• in a completely closed form, the efficiency of heating is only 75% -80%.

Recovering the heating radiator and how to properly connect the heating battery, can be performed using different types pipes. The main thing is to clearly comply with all the indicated requirements and rules. If the radiator connection is performed without errors - for many years, repairing the heating system will not need. Now we know how to better connect heating radiators - but it is even better to ask about this professionals.

So that it was warm in the house, it is important to correctly develop a heating scheme. One of the components of its efficiency is the connection of heating radiators. No matter pig-iron, aluminum, bimetallic or steel radiators You gathered to put, it is important to choose the right way their connections.

Types of heating systems

The amount of heat that will radiate the heating radiator, does not last depend on the type of heating system and the selected connection type. To choose optimal option, I must first figure out what kind of heating systems are and what they differ.

Single tube

One-tube heating system - most economical option From the point of view of costs when installing. Because this type of wiring is preferred in multi-storey housesAlthough in private such a system is far from uncommon. With such a scheme, radiators are included in the highway sequentially and the coolant passes first through one heating sample, then enters the second input and so on. The output of the last radiator connects to the inlet of the boiler heating or to a riser in high-rise buildings.

The lack of such a layout is the impossibility of adjusting the heat transfer of radiators. By installing a regulator on any of the radiators, you will adjust the rest of the system. The second significant drawback - different temperatures coolant on various radiators. Those who are closer to the boiler are warm very well, which are still becoming colder. This is a consequence serial connection Heating radiators.

Two-pipe layout

The two-pipe heating system is characterized in that it has two piping threads - feed and reverse. Each radiator is connected to both, that is, it turns out that all radiators are connected to the system in parallel. It is good because the coolant of one temperature is received on the entrance of each of them. Second positive moment - On each of the radiators, you can install the thermostat and it is used to change the amount of heat that it highlights.

The lack of such a system is the number of pipes when the system is wiring is more almost twice. But the system can easily be balanced.

Where to put radiators

Traditionally, heating radiators put under the windows and it is not by chance. Ascending flow warm air It cuts off the cold, which comes from the windows. In addition, warm air heats the glass, not allowing to form condensate on them. Only for this it is necessary that the radiator occupies at least 70% of the width of the window opening. Only so the window will not fog. Therefore, when choosing the power of radiators, select it so that the width of the entire heating battery was at least a given value.

In addition, it is necessary to choose the right to select the height of the radiator and the place to place it under the window. It must be placed so that the distance to the floor is in the area of \u200b\u200b8-12 cm. If you lower below, it will be uncomfortable, if you raise above - the feet will be cold. It also regulates the distance to the window sill - it should be 10-12 cm. In this case, warm air freely hesitates the barrier - the windowsill - and rises along the window glass.

And the last distance that you need to withstand when the heating radiators is connected - the distance to the wall. It must be 3-5 cm. In this case, the ascending flows of warm air will be raised along the back wall of the radiator, the heating rate of the room will improve.

Radiators connecting schemes

How well they will warm the radiators depends on how the heat carrier is supplied. There are more and less effective options.

Radiators with lower connections

All heating radiators have two types of connectivity - side and lower. With the bottom connection, no discrepancies can be. There are only two nozzles - input and output. Accordingly, on the one hand, the heat carrier is supplied to the radiator, and the other is given.

Specifically, where to connect the feed, and where the reverse is written in the installation instructions, which must be available.

Side Connection Heating Battery

For side Connection Options are much larger: here the feed and return pipe can be connected in two nozzles, respectively, four options.

Option number 1. Diagonal connection

Such a connection of heating radiators is considered to be the most effective, it is taken for the standard and that is how the manufacturers are experiencing their heating devices and data in the heat power supply passport - for such a liner. All other types of connection are less efficiently given heat.

All because with a diagonal connection of the batteries, the hot heat carrier is fed to the upper entrance on one side, passes through the entire radiator and leaves the opposite, the bottom side.

Option number 2. Unilateral

As it is clear from the title, pipelines are connected on one side - the feed, the reverse - the bottom. This option is convenient when the riser runs on the side of heating deviceWhat often happens in apartments, because this type of connection is usually prevalent. When the coolant is supplied from below, this scheme is used infrequently - it is not very convenient to place the pipes.

With such a connection of radiators, the effectiveness of heating is only slightly lower - by 2%. But this is only if the sections in the radiators are a bit - no more than 10. With a longer battery, its far from the edge will be bad or remains cold at all. IN panel radiators To solve the problem, flow extension cords - tubes that bring the coolant slightly on the middle. The same devices can be installed in aluminum or bimetallic radiators, improving heat transfer.

Option number 3. Lower or saddle connection

Of all the options, the saddle connection of heating radiators is the most intimate. Losses are about 12-14%. But this option is the most imperceptible - pipes usually fit on the floor or under it and this method is the most optimal from the point of view of aesthetics. And so that the losses do not affect the temperature in the room, you can take a radiator slightly more powerful than required.

In S. systems natural circulation This type of connection should not be done, but if there is a pump, it works well. In some cases, not even worse than the side. Simply, at some speed of the coolant movement, the vortex flows occur, the entire surface is warmed up, the heat transfer rises. These phenomena have not yet been studied to the end, therefore it is impossible to predict the behavior of the coolant.

Here you will learn how to connect the heating battery in the apartment: the best place For radiators, schemes and connection methods in apartment houseHow to run the heating system.

The launch of the heating system with the first cooling rarers are waiting for all residents of apartment buildings.

So that the rooms were warm, it is important not only how the centralized heating will work in the new season and which preventive work was carried out in the summer, but how best to connect heating radiators in the apartment to get 100% heat transfer.

Running the heating system in a high-rise building

The inclusion of heat supply in high-altitude houses is often associated with anxiety, especially in old buildings. This is due to the fact that it is often preventive measures And checks do not reveal hidden threats and violations. Only letting the coolant on the system under high pressure You can find out how durable it is and effective.

To be without emergency situationsYou need to know how to launch heating in an apartment building:

1. Firstly, the coolant must be served by the pump on low power So that the system is filled in gradually, floor behind the floor.
2. Secondly, his feed must be taken upthat will allow him to displace the air that is going to the heating network during the summer "recreation". With a slow water lift, the load on the pipes and radiators are minimal, which increases their service life.
3. Thirdly, you may need to descend air residuesWhat is done by the workers of the heating network in the attic of the building through special air collectors. It is enough to unscrew the tap and wait when the hiss and whistle will come from the pipes. If a attic room No, the same procedure is carried out on last floor Buildings with the help of the crane of Maevsky.
4. Fourthly it is necessary to drain a little coolant during pipesBy doing this carefully, not to pour apartment apartments.

The full load on the system is given only after these actions. It will save the pipes from the breakthrough and will allow the coolant evenly by allone in its elements.

Best place for radiators

Besides launch centralized heatingWhat makes workers in the heating network, residents should take care of their "plots of work".

In order for in the premises it was really warm, you need to know how to connect the heating battery in the apartment so that it is most effectively heated.

To begin with, you need to check how correctly the place is selected for radiators. Usually, they are mounted under the windows, which is a logical explanation.

The glazing of the room is its weak "link", as even the highest quality windows of colder walls. The air coming from them warms up under the windowsill batteries, which reduces heat loss.

It is not enough to install the heaters under the window opening, you should understand how to properly connect the heating batteries in the apartment so that their sections are warmed evenly.

The norms are indicated in SNiP and correspond to:

1. The radiator length should occupy from 70% and above the area under the windowsill. It is better if this parameter is 90%, then no cold is scary, and the air from the cold window will almost instantly warm.
2. Between the battery and the floor, the distance should be at least 6 cm, and under the windowson, from 5 to 10 cm.
3. From the wall, the heating section must retreat by 2-2.5 cm.

By completing these conditions, you can check how high quality is the connection of heating in the apartment. The distribution of heat fluxes will be markedly by uniform heating of the room. If there are cold zones in it, it means that something was done wrong. Perhaps the point is not in place, but in incorrect connection batteries.

Schemes connecting elements

How do heating in an apartment connect? If we consider all the ways to connect heating radiators in an apartment building, then the most effective that most masters stick will be with an upper feed and lower reverse (diagonal).

It guarantees 100% efficiency, since heating takes place most evenly and with full heat transfer, but it also has a number of minuses:

1. The heat carrier is practically no resistance on the way, which allows it to quickly pass on the system as quickly as possible, not having time to give his heat. To reduce heat loss, it is necessary to install heaters, which have 10 or more elements..
2. Do not very aesthetic pipes lookembedded in vertical riser.

Otherwise, this is a fairly efficient and popular way to connect batteries.

The installation of heating radiators in the apartment with one-sided connection also has good indicators, but they are slightly lower - 97%. In this method, the pipe supply pipe and the disintegrating it is connected on one side of the battery. Not bad method, but more often applicable to small designs.

With one-sided connection, the number of sections in radiators is limited. If heating is required of a large area, you can apply another method.

The most profitable is considered lower connectionWhen the feed pipe and the return goes from the bottom of the battery. This type of connection is used when you need to "hide" pipes in the floor, but it should be noted that heat loss can reach 15%.

These are the main ways to connect heating radiators in the apartment:

The two-pipe connection is considered the best, since the supply of the coolant and its removal is made different pipes. With it is carried out parallel connectionwhich effectively distributes water through the system, evenly heating it.

The two-pipe connection scheme allows you to adjust the heat transfer level using a special valve installed in front of the battery.

How to properly connect the heating battery in the apartment?

To know how to connect heating radiators in the apartment, some tips should be adhered to, which give specialists to beginners:

1. On the places of connecting radiators, you need to put lockable and control devices. This will allow the system balancing and will provide an opportunity if necessary, remove the section for washing or replacing.
2. Acquire finished sets Radiators With suitable connecting details for them.
3. So that the air does not accumulate in the system, need batteries to install under a slight inclinationopposed to crane Maevsky.

Summing up, we can conclude that the most effective for low-size batteries is one-sided connection, whereas for long segments will suit more diagonal scheme. That's how to connect the heating radiator in the apartment to get the maximum comfort.

Of course, in the Design section, talking about the installation of radiators early. Nevertheless, the connection of heating batteries should be thought out already at this stage. In the sense, choose the method of connecting radiators to the pipeline.

What are you speaking, ask you a question?

The most efficient connection of heating batteries

What is known, section radiators have four outputs (or input?):

At first glance, as if without a difference, in which of these places to attach the feed and reverse tube. But it is only at first glance. Because S. different options Battery connects will work with different efficiency.

To make you not tomorrow, I immediately show the way the connection is considered to be most effective. This is:

The radiator with this connection method warms up the most fully, evenly, and its heat transfer is better than with other methods.

Consider for comparison and other ways.

One-sided connection of heating batteries

Such a connection schematically looks like this:

And with such a connection there is a limit on the number of sections: for aluminum radiator Not more than 20 sections.

Lower connection of heating batteries

Here, the feed and reverse is joined to the lower outputs of the radiator:

According to this battery scheme, they are connected when the pipes pass the walls or by the floor (for example, with a collector wiring). As we see from the picture, the efficiency with such a connection is still reduced, up to 88%.

Connecting heating batteries with lower feed

The mirror reflection of the first method, i.e. the flow at the bottom, and the reverse is diagonally at the top:

The efficiency of the radiator with this connection is only 80%.

And another battery connection option at the bottom:

The efficiency of the radiator is even less: 78%.

One-sided lower connection of heating batteries

There are radiators that have input and exit near. Schematically connecting such radiators looks like this:

Such a connection has the plus that the pipes are not noticeable, but the effectiveness with such a connection is also 78%. To dial necessary power Such radiators, you need to put more sections.

How does the method of installing the radiator on the effectiveness of his work?

In addition to the connection method, the efficiency of the radiator affects how it is installed. What am I talking about? Yes, about the following.

Usually the radiators are put under the windows and it is right and good ... if it were not for the windowsill. In the absence of the windowsill, the radiator would not hurt anything to give heat to air, which would be freely raised vertically up. And all 100% heat from the radiator would be on the heating of the room.

Due to the windowsill, the trajectory of air movement changes, the heat transfer is reduced by 3 ... 4%. If the radiator is subject to some kind of niche, then its effectiveness still falls, as much as 7%:

The decorative screens further reduce the heat transfer of heating batteries. If the screen has an air access space at the bottom, the heat transfer is reduced by 5 ... 7%:

And the heat transfer radiators completely closed with a decorative screen falls and in general at 20 ... 25%.

Conclusion: If you really want to hide the heating battery from the eye, choose at least such screens that have access to the bottom.

So, now you know almost (theoretically :)) Everything about connecting heating batteries. And directly about the installation of them in one of the following articles.

connecting heating batteries

Pipes are just installed simultaneously with gas boilers.

It depends on how it will then be arranged a diagram of connecting heating batteries in a private house.

It is better to get acquainted with applicable before making a choice in favor of certain devices. It will help you spend as you can less forces and time to improve the operating system:

• Minimum 2-centimeter distance between the wall and the rear walls on the panels.
• 8-10 centimeters should be equal to the gap, starting from the top of the radiator, and ending with the windowsill.
• 10-12 centimeters - a minimum of the distance from the bottom of the battery to the floor.

In the heat transfer devices, it becomes less, if not comply with the specified norms. The probability that work will be uninterrupted is reduced. And it ceases to be an effective diagram of connecting heating batteries in a private house from the gas boiler.

Radiators must present the adjustment function. It happens automatic or. Therefore, the sets are supplied with heat regulators. Thanks to which indoors are easier to maintain the optimal temperature level.

What happens pipes

When connections, use two-pipe or single-tube schemes.

One-tube option

In addition, heating does not do without such additional elements.

• Temperature regulator. It helps save fuel, maintain the temperature in the rooms at the same level.
• Air vent. Need for oxygen blending. It periodically accumulates in the pipes, because of which it becomes a destructive element.
• Shock fittings. Repair service is easier for those systems that have a large crane.

Expansion tanks - indispensable assistants When building systems of any type. It is released in closed and open.

In a pair of S. circulating pumps They put only closed varieties. Open tanks are trying to post as high as possible. For example, on a house attic.

How to deal with chimney

And in this case there are mandatory conditions. With a diameter, it must accurately coincide the outlet of the boiler. There are other subtleties:

• If the pipe comes to unheated premisesIn these places necessarily insulation.
• It is unacceptable for the presence of connections in places of passage of pipes on roofing or walls.
• Three bends - the maximum amount for the chimney from the boiler to the headband.

Installation of heating batteries: Main stages

Installation rules remain the same for each type of battery. It does not matter which role played the main one, how compounds are performed. The procedure will always look like this.

• First, overlap the entire heating system, drain water.
• Disassemble the battery along with other elements of the old circuit.
• The use of dowels for marking and fixing brackets on a wall surface. The cement solution is needed for pushing places with fasteners to align the surface.
• After that, begin to install traffic jams. Holes for the entrance are available from each pipe, on both sides. Corks for organizing the passage to which the correct thread is applied, wind in places where connections are located. Line strips with additional seal adds the tightness of the entire design. At the top there is a valve mechanism, descending excess air.
• Radiators are hung on supports prepared in advance. Water special devices will help to check how correctly there are levels.
• Installation of a shut-off crane inside passing plugs.
• Batteries are connected to the pipeline.
• Test the entire heating network.

Do not get involved in decorative protective screens. They look, but in the right moment Can close access to thermostats. Because of this, there is a disconnection of heating with insufficient heating.
