Comfortable furnishings in the house - this is not only a beautiful design of the premises and cozy furniture. It is also warm. And ensure complete heating of the premises, especially in a private house, it will help exactly the warm floor. However, it is not always possible to equip electric heating, and people often stop on the water heating system. At the same time, if there is no option to connect it to centralized system Heating, it is necessary to install an electric shock for a warm floor. It remains only to decide which model to choose and how to install it.

Features of the work of outdoor heating without radiators, floor heating boilers

He is very often thinking about the heating of the floors in the winter period of the year, when so you want to move around the premises of the barefoot, but the floor covering is so cold that it is not possible. The option to make it more pleasant and comfortable tactular is the laying of a warm floor system.

There are different heating systems of floors - water, electrical, infrared. And often owners of apartments and houses make a choice in favor of the first option. The system will consist of main pipes for which the coolant circulates is hot water, as well as a boiler that heats this water.

On a note! In new buildings, heating of the floor can be connected to the central heating system - it will provide special taps to connect the pipes of the heating system. But in private houses, as well as the apartments of the Old Fund, the connection to heating is impossible, so there are two options - the use of other heating systems, or the installation of a water heating boiler.

The boiler is often used to heat the premises of various purposes - apartments and garages, houses and offices. it reliable device It has acceptable dimensions and not dangerous for use in a residential room. It also has very comfortable system temperature control, which will allow control of the microclimate indoors. This will give the opportunity to leave the unit unattended included for a long period of time.

On a note! The boiler refers to K. autonomous System Heating, it will save a lot of money that will be spent on the usual additional heating of the room.

However, specialists are not recommended to use for the heating of the room alone with a heap system without heating radiators. The fact is that in order to warm up the house to a comfortable temperature, you will have to warm up the floors at least by +30 degrees, and this can negatively affect outdoor coatingIt will also be unpleasant and man - moving around such floors hot. Also, at the expense of radiators, the air in the room can be warm up much faster than the warm floors. The latter longer are heated even due to the fact that they are closed with a screed, which you also need to warm up.

On a note! Efficiently and economically work on low power Only electric boilers can. All others will burn too much fuel to maintain low temperature, and this is unprofitable.

Electric boiler - this is the comfort of your home

That is why the warm floor system should warm only the surface of the floor, the rest of the room should be basked at the expense of radiators. And, nevertheless, for the correct and economical work of the equipment it is worth purchasing a heating boiler.

Types of boilers for water heating of floors

Boilers for heating the coolant, that is, there are several types of water. They differ in features of the work, installation and operation, as well as the type of fuel, at the expense of which function.

Table. Types of heating boilers.

A type	general information
	Such boilers are heated only the coolant (in our case - water). So that they can be used for something else, it is necessary to purchase boilers, heat exchangers, etc.
	Boilers of this type can be used to heal water and for the purpose of heating. Heated in such an unit is possible due to the presence of a heat exchanger or boiler already directly in the device itself.

Also boilers can be divided into two categories at the installation site. They are wall mounted, outdoor. Outdoor, as a rule, have a greater power than suspended. But the latter is much more convenient in the installation plan and not so costly in service.

Diesel boilers

In this case, the fuel is the usual wasolar. These units are produced and very effective, differ in absolute autonomy, that is, they do not depend on whether they are connected to any communications (gas, electrical networks, etc.). They are easy to install, easy to use and have high rates CPD with a small fuel consumption.

diesel boilers heating

Solid fuel boilers

Fuel for these aggregates serve firewood, fuel pellets. The principle of work resembles burning firewood in a regular furnace. But at the same time, combustion occurs at high temperatures (from +250 degrees) and without air access. Heating of the coolant occurs due to the release of hot smoke during fuel combustion.

In residential premises such boilers are rarely applied, the usual sphere of their use - production, agriculture. These aggregates in the house require constant attention, as well as loading fuel, which complicates operation.

On a note! If the boiler has a camera where fuel burns, closed type, it can be set anywhere. For equipment with an open type camera, you need to look for a separate installation room in the house.

solid fuel boilers heating

Gas boilers

It is not difficult to guess that this type of boilers works on gas. The case of these devices is usually made of cast iron or steel, from which the service life and simplicity of installation will depend. Steel boilers are much easier cast iron, they have small dimensions and are easily repaired. However, the service life is lower. That is why cast-iron aggregates are more expensive, as they are distinguished by increased reliability indicators. Devices can operate both on the main gas and on liquefied from cylinders. Pretty economons, and for heating only the floors you can take a low-power installation.

To connect to a heap system, these boilers are not recommended. The reason is simple - they, of course, are able to maintain the temperature of the water at low indicators (about +45 degrees), but in fact, they are actually designed for heating the coolant at least +80 degrees. Because of this, the CPD of the boiler will fall very much (up to 15%).

But still there is an use option gas boiler To work with a warm floor system. To do this, you will have to use a mixing unit equipped with a special distributor and circulating pump. However, this will increase and the cost of purchasing equipment and its installation.

On a note! By the way, it also applies to other types of boilers, with the exception of electrical units.

Boilers on electricity

These aggregates working on electric Tokcan be used in any spheres and are best suited for connecting to the floor heating system. Connecting this boiler is simple, despite the seeming complexity. Such aggregates will allow to organize low-temperature heating - which is as needed for a warm floor - due to the possibility of adjusting the temperature of the outgoing coolant flow.

On a note! The higher the indicators of thermal insulation indoors, the less power will have to acquire a boiler.

How to calculate the power of the boiler for water heating?

Calculate power is needed in order to select an unit that is suitable for heating floors. This indicator depends on many factors, but it is simply calculated simply enough, based on the fact that for heating 10 m 2 of the area of \u200b\u200ba brick and well warmed house with a height of the ceilings up to 3 m, only 1 kW of the unit of the unit will be required. Thus, the specific power will be 100 W / m 2.

On average, the temperature of the coolant should be about +70 degrees, in this case it is necessary to increase the boiler power by about 20%. Also, an increase in this indicator should be carried out and with any additional load on the unit. That is, if there is also a cumulative boiler, then the power should be added about 30%. In the event that the heating system of floors will act as an addition to radiator heating, its heat transfer will be no more than 50 W / m 2.

Tip! If in the future the areas of heated premises will be increased, then install the boiler you need such a power that will allow you to damn and extensions.

Criteria of the selection of the boiler

Unfortunately, specially intended boilers, which can be connected to a warm floor system, no. Of course, there are models in the technical passports of which it is indicated that they can work in this mode, but in general it is only one of the functions of the equipment.

The choice of equipment for heating floors should be made in several criteria:

• the ability to adjust the heating of the coolant and floors;
• the power of the unit;
• type of fuel;
• compatibility with floor heating system;
• high efficiency;
• easy to use, repair, maintenance;
• safety system;
• manufacturer;
• easy installation.

Fuel each should choose the one that will be most profitable. In some regions, it is cheaper to carry out heating using electricity, in the other - gas.

One of the most important parameters of the selection of the heating boiler is the possibility of its connection with the floor heating system. This is necessary in order to be able to install the temperature of the coolant, which will circulate without prejudice to the equipment and budget. At the feed, the heating system should produce only + 35-45 degrees, and on the return - about +25.

On a note! If the house is heated by radiators connected to the boiler, from which the heating system of the heating floor is left, then select the unit will be easier. If the heating of the premises will be made not at the expense of the boiler, it is important to choose the model that will allow you to install a low floor heating temperature.

It is also important to assess the area of \u200b\u200bthe room in which the warm floor system will be mounted, the materials from which its finishing finish is made, as well as the screed parameters.

What boilers can be combined with warm floors?

The best option of the boiler for heating floors is an electric flocity. More regardless of whether it is the induction or electrode. It has an optimal efficiency, even working at low facilities. In a small house, such equipment can be connected in the floor heating system directly. In large rooms, it is better to connect with a special distribution mixing node.

The boiler works automatically and practically does not need human control. It is easy to install and easy to maintain.

Condensate gas boilers can also be used, which can work effectively with a slight heating of the coolant. But the usual gas units need to install a mixing unit in which controlling elements will be provided. it excellent option To combine radiator heating and a warm-alone system.

Solid fuel and liquid fuel boilers - the option is not the best, although they can be applied to the organization of the floor heating system. For them, the installation of a mixing unit with thermometers, controllers and other additional equipment is necessary. Yes, and it is very difficult to debug the desired temperature with their help - it is too hot a coolant, it is too cold.

Tip! To cope with this, you should acquire and install the heat accelerator. But this is not cheap.

What brand is the best

An important factor when choosing a boiler will be a brand under which equipment is produced. Manufacturers who deliver heating boilers To the market, there is quite a lot. We will get acquainted with the basic and most popular of them, as well as with the brands of boilers and their value. The emphasis will be placed on electric boilers, since they are the optimal option.

Table. Manufacturers of boilers, characteristics of equipment and its cost.

Name model	Manufacturer Country and Cost	Description
	Germany, from 40,000 rubles.	These are the onan wall-mounted boilers of various capacities. Eco-friendly heat sources that are used to heat the premises of various purposes, including residential.

	Ukraine, from 9,000 rubles.	Tannic wall boilers. Work without monitoring human. There are a duct sensor that turns off the system if the water stops circulating.

The most popular are aggregates of Ferroli (Italy), Viessmann (Germany), Russian (Russia), Dakon (Czech Republic). The cheapest is, of course, boilers russian production. Importing units are usually more expensive than domestic minimum by 20%.

Instructions for connecting the boiler to the warm floor

Step 1. According to the installation rules of the warm floor system, the draft coating is closed by a layer of thermal insulation, waterproofing, reinforcing the grid, to which the pipes for the coolant under the scheme are screwed.

Step 2. An electrocotel is installed on the place intended place.

Step 3. All pipes for the coolant are summed up to the boiler.

Step 4. Installation and connection to it all pipes for the coolant and boiler are made.

After that, by filling the coolant, the tightness of the system is checked, and then the warm floors are poured cement mixture (while the coolant must be inside the pipes). After drying the screed system, the heating system can be used.

Having worked out all possible options, you decided to use water warm floors for heating at home. It remains to choose and purchase a water treatment to work with these sexes, and then the question arises - how the boilers for the warm floor are correct. The purpose of this article is to help with solving issues related to the choice of the boiler serving the floor heating system.

Criteria of the selection of the boiler

Special water heating plants intended for a warm floor do not exist. True, some manufacturers of gas units offer models with a warm floor mode, but it is only a built-in function of limiting water temperature. The fact is that in radiator schemes and outdoor heating a different temperature of the coolant. In the first case, it reaches 95 ºС, and in the second - maximum 55 ºС, the average temperature in floor circuits is 35-40 ºС. With the "Warm floor" mode, the heat generator automatics limits it at the level of 45 ºС and it turns out that the boilers have been working in a certain power together with floor heating in the random, and this is irrational.

Maintenance of water warm floors can boiler any kind, is all the case in its correct strapping and connecting to heating circuits to thermal power The boiler was used as efficient as possible. To begin with, we will define the criteria for which the selection of the boiler installation that maintains water heating is required:

• compatibility with outdoor heating systems;
• efficiency;
• convenience in operation and maintenance;
• mounting complexity.

This list does not include the cost of heating, because each homeowner seeks to use the most affordable energy source for heating. For some, this is natural gas, someone brings cheap firewood, and someone favorably trample with electricity due to the fact that a multi-tariff electricity meter is installed in the house. Therefore, our task is to consider all possible options so that everyone can make a reasonable choice of a boiler for warm water floors.

The degree of compatibility of heating equipment with outdoor heating contours is the ability of the boiler to maintain a low temperature of the coolant at a sufficiently large consumption. If it is impossible, additional equipment should be provided, which allows to reduce the temperature of the water and at the same time ensure consumption taking into account the power of the warm floor.

The efficiency of the heat generator affects the consumption of energy carriers, and the convenience of operation is determined by time, which is paid to the homeowner heating equipment. That is why these criteria need to be considered when selecting the source of heat, as well as complexity mounting work and strapping affecting the original cash investments.

First we list, and then consider in detail all kinds of boilers for warm water floor:

• electrical;
• gas;
• solid fuel;
• on liquid fuel.

An ideal option in all respects is an electric boiler regardless of its type (lane, electrode or induction). By spending 1 kW of electricity for the production of 1 kW of warmth, the unit absolutely calmly supports the temperature of the coolant at a given level, without licking in efficiency. When the floor heating device in small houses, the heat generator can be connected to the contours directly by setting the required temperature on it.

As for large cottages, in this case, electric boilers for warm sex are joined by the system through the distribution unit - the mixing unit will be mentioned below. The aggregates are fully automated and do not require interference in their work, as well as frequent maintenance or cleaning. Again, they do not need chimneys, which greatly simplifies the installation. The only drawback is the availability of necessary electrical power The network, the rest of the electrocotel, is the best that can be offered for outdoor heating.

Council. Since the Water Heat Connection System itself assumes the presence of electricity for the functioning of the circulation pump, then when choosing a heat source, you should not focus on its non-volatility. Without electricity, it's still not to do.

Gas boilers

Theoretically, the thermal generators on natural gas can maintain water temperature at 40-45 ºС, but lose their effectiveness. Why? Everything is simple: the heat exchanger of the installation is calculated on the basis of the normal operating mode with the temperature of the coolant 80-90 ºС and the difference between the feed and return pipe in 20-25 ºС. Then the heater issues the declared thermal power. In our case, the gas gas boiler must provide midh temperature 40 ºС with the difference between the supply and return 10 ºС. The efficiency of the unit will inevitably fall by 10-15%, so it is not recommended to connect the gas boiler directly to warm floors.

To combine gas heating equipment with outdoor heating contours without loss of efficiency, you need to use a mixing unit with a circulating pump and a distributor by room. How to do this, displays the scheme of warm floors with a gas boiler:

In the main contour with the boiler, the water circulates with a temperature schedule of 80/60 ºС, a penetrated by the pump in the boiler room. Inside all contours of outdoor heating, the coolant with a chart 40/30 ºС moves another pump, and the three-way valve mixes hot water from the external network to them as needed. Such a connection of water warm floor to the gas boiler allows you to securely and economically operate the entire system. At the same time, the intervention in its work is not required, as applies to the installation, then the costs will be higher than in the situation with the electric heater.

All of the above equally applies to diesel (liquid) aggregates. According to the technical specifications and the degree of automation, they are close to gas, so the connection of the warm floor to the boiler on the diesel fuel is also carried out through a mixing unit that performs the distribution functions.

Solid fuel boilers

This type of heat generators requires constant attention and maintenance, and on compatibility with the warm floor, they are most problematic. An exception is the pellet boilers, but they need to visit them more often than to gas or electric. To keep the temperature of the coolant during the burning of firewood at least 60 ºС, the automation has to constantly "stroke" the furnace, limiting air intake, so a solid fuel boiler for warm floors will also lose in efficiency.

To avoid this, it is more correct to use the buffer capacity of a large roominess or a hydroaccumulator. Then the unit will be able to fully use the heat of the combustion of firewood, transmitting it water in the tank, and outdoor heating will take from it as much as required. Thus, it is possible to increase the pause between the fuel boots. Below is a diagram of a warm floor connection to the boiler burning. different types Biomass:

As can be seen from the scheme, the installation of the heating system from a solid fuel boiler will be the most difficult and expensive, which should be considered when choosing a heat source.

Conclusion

Of all the above, we can conclude that it is more convenient and cheaper than all to put an electric heater, a little more complicated and more expensive - gas, and the most expensive and uncomfortable is a solid fuel boiler. Do not forget about the device "Pie" and the base of the warm floor, which also costs a lot of money. How it will pay off afterwards - each homeowner decides in his life situation.

For the heating of the dwelling, the "Warm floor" system is very convenient and efficient.

It is coils located under the coating of floors.

Despite all the comfort of this system, it is very expensive.

How to calculate the power of the boiler

In order to find a suitable power boiler, you need to make calculations of heat loss. For calculations, 2 kW of the boiler power is usually taken by 10 m2 area of \u200b\u200bthe room with a 2.5 m high.

Gas boiler for "warm floors"

Why is the gas boiler need to be used to provide heating "Warm floor"? For this there are several reasons:

• Gas is affordable fuel.
• Gas boilers are very convenient in operation.
• The possibility of using gas boilers in the apartment.

But the main reason lies in the design features of the condensation gas boiler. To make it clear what we are talking about, let's consider the 2 main types of gas boilers:

• Convection gas boiler is a traditional model boiler. It includes one heat exchanger. Heating occurs due to heat release during gas combustion. Such a boiler is convenient, practical, and also has a low price.
• The condensation boiler is the same convection boiler, only upgraded. That is, he has all the same qualities, but in addition it has its advantages.

Due to the additional heat exchanger (economyzer), an additional heating of the coolant occurs. The economizer is located almost at the exit of combustion products from the boiler. Heating occurs due to the hidden energy of the water vapor, which is present in the flue gases. Steam condenses on the walls of the heat exchanger, thereby transfers its energy to the coolant.

Thus, the condensation boiler has a useful coefficient (efficiency) by 15% more than convection.

Attention!
In order for the process of condensation of water vapor on the walls of the heat exchanger occurred intensively, it is necessary that water in the heat exchanger can be as cold as possible. The optimal temperature is not higher than 400c.

The condensation process and the "warm floor"

According to the instructions, cold water can not be supplied to the working boiler - it can adversely affect the durability of the heat exchanger, but this rule applies only to convection boilers. In the case of a condensation boiler of the temperature skew, since cold water pre-heated in the economizer to optimal temperature. In the main heat exchanger will come the heated water.

If insufficient water will be supplied to the condensing boiler, then it will simply lose all its advantages, because the steam will not be condensed, which means that the heat carrier will not be heated. Therefore, water in the reverse line should be cooled as much as possible. In this we will help warm floors.

Heating "Warm floors"

It turns out that when used condensation boiler The heating system "Warm floor" is not simply free, but is also necessary to reduce the temperature in the reverse line. Kind by-effect In the work of the main heating system.

Features of warm floors

If in the coil under the floor to submit water from heating radiators, the floors are warm almost the same as radiators are too big temperature. That's what it is distinctive trait "Warm floors" from traditional heating. Their nominal feed temperature should be within 40-450c. How to fulfill this condition?
The solution to this question carries in itself very simple design. Its name hydroelectricity. It is a vertical accumulative tank. In this tank, water is assembled from direct and reverse lines. According to the laws of physics, hot water will be collected in the upper part of the tank, and the cold in the bottom.

How to install a gas boiler in an apartment with warm floors

Installation of a gas boiler better entrust to experts. And if it is performed independently, you need to follow all the requirements specified in the instructions. The strapping of the boiler must be done in accordance with the drawing. To connect pipelines to use only factory parts and seals.

The heating system must be already mounted, it will only remain correctly installed and connect the hydraulic system on one side with the heating system, and on the other hand with a boiler.

On a note.
To ensure the uniform distribution of the coolant between heating circuits, you need to install 2 collectors - one on a straight line, and the other on the reverse. At each output from the collector, install the locking fittings so that it is possible to turn off each individual circuit.

The hydroelectron has several outlets located at different levels in height:

• The topmost outlet is a submission to the main heating system. Thus, radiators are consumers of water with the highest temperature.
• Bottom outputs produce a coolant with a smaller temperature, it goes to "warm floors".
• The reverse lines of the "warm floors" and heating radiators are cut into the lowest point of hydraulic, at the same level there is a fence of cooled water to a condensing boiler.
• To ensure more accurate temperature control for each "warm floors" circuit, its circulation pumpwhich automatically adjusts the speed of the coolant.

The figure shows in detail the heating circuit of several heating circuits using hydraulic and two collectors.

The collectors are installed after the hydraulic fracture and to it on the "return", if you look at the movement of the coolant.

The most optimal option to ensure heating with the "warm floor" will be a gas double-circuit boiler with a forced burden in the suspended version.

Such a model is well suited for a private house of medium sizes and even in the apartment. It will only remain to ensure the output of combustion products. Coaxial tube for a gas-gas gas boiler replaces the traditional brick gas duct. Therefore, the installation of an aggregate is possible even in the absence of a special gas plant.

The owners of private houses, preferring outdoor heating systems, often cares how to choose a boiler for a warm floor. In fact, the choice is not a problem, for heat supply of water heating circuits, any heating unit operating at some kind of fuel is suitable. The snag is in the other - how to correctly connect this or that heat generator. Here it is necessary to take into account the many nuances, which will be discussed.

How to choose a boiler?

The heating unit for the private home of the hosts is usually asked to benefit from the use of any energy carrier from those in stock. This approach is the right one, and it is necessary to confess when choosing a source of heat for outdoor heating. That is, selecting the appropriate heater, you need to consider the following factors:

• which energy carrier is most profitable;
• what kind of thermal power is necessary;
• as electricity is supplied in the region of living, frequent shutdowns;
• comfort when operating, including simplicity of service;
• how easily the future heat source is suitable with outdoor heating contours.

In the context of this article, the last item is of particular interest. The fact is that no manufacturer does not produce special boilers for a warm floor. In some models of gas heat generators, it is possible to meet only the function of working with water warm floors and nothing more.

The main difference between the radiator system of heating from the floor heating circuits is the temperature of the coolant. For feeding into radiators, water is heated to the maximum up to 85 ° C, while in water floors it should not exceed 55 ° C.

The optimal temperature schedule in the heating system of floors is 35-45 ° C on the supply and 25-35 ° C in the return pipeline. If warm floor and radiators are involved in the home heating, supplied with heated water from one boiler, it does not affect the choice of heat generator. Another question is when the batteries are not envisaged, and the boiler installation should serve only the low-temperature floor heating system.

Not every source of heat is able to maintain the temperature of the coolant 30-40 ° C. The question is solved by different ways Straps of the heating unit. The complexity of the docking depends on the variety of the used boiler for warm water floor:

• gas wall or floor;
• electric;
• solid fuel;
• automatic pellet or coal.

How compatible these boilers are compatible with warm floors and how to connect them correctly, consider separately for each of the varieties.

Warm floor from the gas boiler

If your dwelling is gasified, then the choice of heat source operating on natural gas will be logical. It is only necessary to correctly pick it up in power and compare the selected model with the operating conditions. With frequent power supply interruptions, it is easier to put an outdoor non-volatile heater with an open combustion chamber than to buy and operate gasoline or diesel electrical generators.

IN Russian Federation Both Belarus use natural gas to heat the dwellings is one of the most favorable options in terms of energy payment. In Ukraine, the situation is different, there the price of gas is so great that the first place for the benefit occupy solid fuels - firewood, coal and pellets.

When with the supply of electricity, everything is in order, it is easiest to install and connect a wall gas boiler for a warm floor. It is good because it has its own circulation pump, an expansion tank, safety valve and net filter. In this case, the diagram of connecting a warm floor is very simple: the heater is connected to the distribution comb tubes directly, but taking into account such nuances:

1. At the entrance and outlet of the heat generator must stand cut-off ball valves.
2. The capacity of the built-in expansion tank (usually no more than 10 liters) should be enough to maintain the heating system. Calculate the volume of water in the pipes and compare with the tank capacity. If the last less than 1/10 part of the total coolant, then put the additional expansion tank on the return pipe before the input to the boiler.
3. If the design of the wall heating unit does not provide a built-in expansion tank, put it separately on the piping of the return, as mentioned above.

Below in the diagram is shown how to connect the warm floor to the wall gas boiler. As you can see, the circulation pump is missing in the system, since the boiler unit is involved. The distribution collector without a mixing node is equipped with the thermal heads of the RTL type, more about this type of water circuits are told in this article.

The expansion tank is placed when the boiler is too small or absent

Outdoor gas heat generators, with rare exceptions, not equipped with pumps and expansion tanks. Therefore, its connection is carried out by a similar scheme, but with the missing elements in the strapping:

IN closed systemsWhere and warm floors include, you must need a security group

When it is necessary to install a traditional scheme, where the warm floor and radiators get heat from one boiler, the connection is made as follows:

Note. The scheme contains a method of strapping using servo drives acting together with room thermostators. The heater can be connected without automation by the same scheme.

Features of the work of outdoor heating without radiators

Let's start with the fact that experts are practitioners not recommended to use heating with warm floors without the support of the radiator system and that's why:

1. To inform the room a sufficient amount of heat, we will have to lift the surface temperature of the floor to 30 ° C and above, which is already uncomfortable for living in the house.
2. Batteries equipped with thermostatic valves react faster to temperature changes in the room than heated floors. The latter are more inert due to the massiveness and heat capacity of the screed.
3. Any water boilers except electrical cannot work efficiently in the minimum burning mode when you need to maintain a low heat carrier temperature. Imagine that the efficiency of gas and solid fuel units drops by 5-20%, and think about how much fuel you will burn inust.

If the gas heat generator is translated into normal operation, putting the water heating temperature at least 60 ° C, then the burner will often wear and disconnect (so-called tact will appear), since the total heating system is not required. a large number of Warm. For the heater, such a regime is unsuitable, it can quickly fail.

For normal collaboration of gas and other boilers with heating with warm floors, but without radiators, there is an optimal output - installing a buffer container. Even the reservoir of small size will allow to avoid the "tact" of the aggregate, burning natural gas.

An example of the installation of a buffer capacity Consider with a solid fuel boiler, which can not do without the heat supply of floor heating without it.

Connecting a solid fuel unit

Did you choose the heating of your house to firewood through warm floors without connecting radiators? Prepare for significant investments of funds in the strapping of a solid fuel boiler, since with such a scenario without a buffer capacity can not do. The reason is that wood heaters need to drop heat somewhere, otherwise the water shirt of the unit can boil.

Moreover, the heat generator on solid fuel is unable to heat the coolant to just 40 ° C, its minimum operating temperature is 55 ° C. If it is lower, condensate is formed in the combustion chamber, adversely affecting the metal walls. Even in a cast-iron boiler, not subject to corrosion, a layer of a plaque is formed due to condensate, which prevents efficient fuel combustion.

So that the solid fuel boiler functioned with maximum efficiency, and you burned firewood with the greatest advantage, you need to maintain the temperature of the coolant at 80-90 ° C, which is absolutely not compatible with warm floors. So, the buffer container is needed - the heat accumulator.

During the maximum burning of firewood of excess warmth will accumulate in the heat accumulator, and the floor heating system will gradually select the desired amount using the mixing unit, as shown in the diagram:

Cutting cranes for the heat accumulator are not shown in the scheme

According to the proposed scheme, you can connect any solid fuel or gas boiler, this is the best of existing optionsAlthough not the cheapest. In the same way, pellet and coal automated heat generators are encouraged. The calculation and selection of the volume of the heat accumulator used is a separate topic considered here.

Outdoor heating with electric concrete

To work with water circuits, outdoor heating is perfect for any type of electrical heat generators:

• Shadan;
• electrode;
• induction.

Household electric shock for a warm floor is the easiest and most convenient option. Regardless of the type and design, these heaters are able to maintain in the heat network any temperature without loss of efficiency. Therefore, they do not need buffer containers and complex connection schemes. To attach the electrical unit to the comb of heating contours, you can use the schemes above for gas boilers.

As a rule, tanne electrocostiles are made in the wall design and are equipped with their own pumps and expansion tanks. More simple modelsAlso induction and electrode heat generators are connected by analogy with floor gas boilers. The missing work items are added to the scheme, only in addition is installed electric cabinet Control.

Step-by-step instructions for installing and connecting an electric unit to water heating is presented in a separate publication.

For the successful and long-lasting operation of a warm flooring system, it is allowed to use any boiler from now existing ones. Not the type of heating unit plays a role, but its correct connection to the distribution collector of outdoor heating. Other selection criteria, such as power, functionality and type of energy carrier are selected according to the standard algorithm.

Choosing a heat source and knowing than it is fraught with a dock with warm floors, you can choose the equipment and elements of the strapping in advance. This will give you a future picture of the financial costs of installation, where the payback of a specific heating system is calculated.

Think twice before introducing outdoor heating without radiator. If you have high requirements for interior design rooms and you do not want to see the heating devices under the windows, apply a more modern solution - plinning convectors or air heaters embedded in the floor.

Heating at home or apartments in winter time And the costs of it are worried almost all. Warm water field, which can be mounted independently, will good decision tasks. The pipes on the boiler (or other heating system) are connected to hot water circulates. Pluses of this system: low cost of electricity and the ability to independently regulate the temperature in the room. It is very important to choose an economical boiler that is as suitable for specific conditions. Most. an important indicator There will be a thermal power of heating equipment.

Warm floor boilers

Boilers are divided into single-circuit and dual-circuit boilers.

Single-mounted boilers. Single-connecting boilers in the heating system provide only heating of the coolant (only room heating is possible). To expand the scope of application of single-circuit boilers (providing hot water) Additional devices are required:

1. cumulative boilers (providing hot water supply);
2. heat exchangers;
3. mixing nodes for heating circuits;
4. and other.

Double-circuit boilers - Multitasking devices: provide heating and heated water. The second function is performed by equipping the boiler with a built-in flow heat exchanger or built-in cumulative boiler.

Variety of installation boilers:

• floor (power up to 120 kW);
• suspended wall (power up to 35 kW).

Wall boilers (most often it is an atmospheric type device) is more convenient from the point of view of installation and require less expenses.

For boiler S. closed chamber The combustion does not need an additional area in the form of a separate room. Wall boilers are equipped with a circulation pump and other equipment for the boiler room. To enter into operation it is enough to attach the heating pipeline and pipes for hot water. Boilers with built-in storage boilers per 100 liters are ready-made mini-boiler

Types of boilers for warm water floors

To arrange warm water floors, boilers operating on gas, electricity, solid or liquid fuel are used. Each view has its advantages. Gas, and autonomous - diesel are most economical.

Gas boilers.The body of gas boilers can be made of steel or cast iron. Steel units are distinguished by low weight (about half easier cast iron at the same power), small dimensions and good maintainability. Cast iron devices are more voluminous and expensive. Outdoor gas boilers modern generation Suitable for main Gaza And for liquefied. Small wall-mounted gas boiler dimensions allow accommodation in any convenient location, and the power of 7-30 kW is enough for a small cottage.

Diesel boiler Works on diesel and distinguished by high efficiency and performance. During the operation of the equipment there are no unpleasant odors. Other advantages of this type of boilers include simplicity of installation, convenience of maintenance and control, high efficiency and low fuel consumption. Liquid boilers due to the special mode of operation based on a smooth decrease in water temperature in conditions of elevated ambient temperature, differ in economy and environmental friendliness.

Solid fuel units For the arrangement of water heat, there will be a completely autonomous source of heat supply. They are considered a good alternative to liquid-fuel, gas and other types of heating equipment. Fuel combustion occurs according to such a scheme: Firewood, laid on the grate, are set on fire. After that, the boiler door closes, and the smoke is turned on. In interior chamber boiler on firewood affects heat (250-750 ° C) without access of oxygen. There is a charring and the release of wood gas, which heats the thermal carriers. Scope of application of solid fuel boilers: residential and industrial premises, agricultural facilities.

Electric boilers Suitable for residential and non-residential facilities equipped with water outdoor heating. The system connects to the boiler with special equipment and additional devices. The selection of the power of the device affects the area of \u200b\u200bthe room, its condition and other factors. The most optimal power can be selected in rooms with good thermal insulation of walls and ceilings (for example, in new buildings). If there is good thermal insulation, then the manufacturer for heating 150 sq. M. Square considers a sufficient power of 12 kW.

For tandem "Electric boilers - warm water floors", manufacturers recommends the following combinations:

• heating area 250-450 square meters. M - Power of a boiler 36 kW;
• heating area 220-350 square meters. M is a 30 kW boiler power;
• heating area 140-300 square meters. M - power boiler 12-24 kW;
• heating area up to 70 square meters. M - the boiler power is about 6 kW;
• heating area up to 30 square meters. M - Power of the boiler 6 kW.

Electric or liquid fuel boiler?

To compare two types of boilers, it is necessary to take into account all factors. Despite the low cost of diesel fuel in comparison with electricity, all cost estimates will show a real picture.

Initial cost of buying equipment and installation cost
Electric boiler - ready-to-use device. The liquid-fuel unit will require additional costs for the purchase of a boiler, mounted burner, fuel storage tank. The difference in the consuming part 2.5 times in favor of electric.

Installation of the electric boiler will cost several times cheaper, since all the necessary elements for controlling and safety of the equipment are mounted in its housing. A liquid-fuel device needs installation of additional devices: chimney, fuel tank, mounted burner.

Operating costs
For the service of a liquid fuel boiler, expenses are needed (several hundred dollars a year) on regular maintenance and cleaning. Additional inconvenience is associated with the need for permanent orders for the supply of fuel. Electric boilers do not require listed operations.

However, electrical devices There are also disadvantages.

1. For the work of the boiler, several dozen kilowatt energy is needed (1 kW per 10 m2 of the area. The height of the ceilings is up to 3 m, and the room is well insulated at the same time). Allocate this amount of electricity is possible not in all areas.
2. The cost of electricity is high and there are interruptions with power supply. For the suspension, with frequent interruptions with electricity supply, a backup solid fuel boiler is often used.

If a water heating It is done in a house or apartment within a big city, the electrocotels are most preferred of all kinds. This is due to the stringent environmental requirements and coordination problems.

After analyzing the situation, you can allocate A number of advantages of electrocotors:

• low cost;
• compactness and low weight;
• easy installation, chimney is not needed;
• safety (no open flame);
• ease of operation;
• can be installed in any room;
• service is simple;
• eco-friendly: no emissions and odors;
• silent.

Parameters of choice of boiler

Heating installations depending on the characteristics provide various heat efficiency, suitable for certain Square and operating conditions.

1. Power.The required parameter is determined by the area of \u200b\u200bheated room and the level of heat insulation. The manufacturer indicates the area to which the boiler is designed, provided that the building is well insulated. If heat losses Unknown, then you need to choose a boiler, the power of which is designed to heat the area by 25% more real. Purchase equipment with excess capacity is impractical, as overheating and breakdown of the device will occur. In the event of the installation of the boiler in unheated room, It is necessary to calculate the power to attract the heat efficient specialist.
2. The ability to control power. Gas installations can be equipped with power control system, and can be without it. To adjust the equipment, autorem or manual control can be used. Automatic systems Controls are more economical. In this case, the user only specifies the necessary parameters, and the automation ensures accuracy and smoothness of the feed gas mixes To the burner. Also, when using automation, the frequency of the total turning off the burner is reduced, due to which the service life increases.
3. Energy dependence. The use of electronics in the control system of electrical pumps for forced circulation increases the capacity of the boiler, but simultaneously depends on the stability of the energy supply and reduces its autonomy.
4. Type of water heating. If necessary to boiler (including industrial gas device) Provided not only the heating function, but also produced heated water for household needs, it is necessary to choose two-integral modelthat warms the water in the flow mode. If a lot of performance is needed, then you need to stay on the accumulative version. Boilers can be embedded in boiler or autonomous and connect to installation. Remote models can have a very large volume (several hundred liters), while the built-in is limited to the size of the boiler.

Calculate the required power thermal equipment It is necessary for the correct choice of the boiler. Approximate required power for heating country house It is calculated on the basis of such data: to drop 10 m2. Square, 1 kW of power is needed, that is, it is assumed that the specific power is 100 W / m2.

The calculation is quite rough, and it is suitable for a brick house with small heat lines: the building must be well insulated, the ceilings - no more than 3 meters high, metal-plastic windows with double double glazing.

To increase the resource of the heating system and the heat reserve, it is necessary that the temperature of the coolant is at 65-75 ° C. For this, the power of the boiler (in ideal conditions) is increased by 20-25%.

With any additional load, an increase in power is required. In the case of ensuring hot water with a cumulative boiler, it is necessary to add another 30-40%.
If in the future it is planned to expand the heated area, the arrangement of water heat, the water heating pool, the boiler must be purchased immediately with a power designed for further changes.

If the warm floor is planned as an element that complements radiator heating and an increase in the comfort of living, its heat transfer is considered not higher than 50 W / m2.

Gas boiler installation requirements

Requirements for the room:

• For the boiler room, a separate non-residential room is necessary.
• The height of the ceilings into the room is at least 2.2 m.
• The size of the room at the rate of 7.5 m3 per boiler.
• Floor area per one boiler 4 m2.
• Door opening width from 80 cm.
• The window size is determined at the calculation: for every 10 m2 area - a window of 0.3 m2.
• Be sure to present a hole for air inflow (per 1 kW of the boiler power - 8 cm2).
• The boiler must be installed at a distance of at least 0.1 m from the walls, which are plastered or finishing the walls is made of non-combustible materials.
• The installation of devices in refractory walls is allowed in case of their insulation with roofing steel, superimposed on a sheet of asbestos with a thickness of a minimum of 0.3 cm.

Requirements for communications

• Electricity characteristics: single-phase current, voltage 220 V, Current 20 A. An individual network protection automatic (gas station) is installed. Established grounding.
• On the gas highway, a locking unit is mounted, for each boiler its own.
• Submission of water and the possibility of its connection to heating systems and hot water supply (DHW) of the building.
• Sewerage provides emergency stations from water supply and boiler systems.
• Communication parameters (gas pressure in gas highway, water pressure, etc.) must comply with state standard standards.

Heating system In a private house, this is perhaps the most optimal option, which is becoming increasingly relevant for a Russian person every year. The user, choosing this method of heating, becomes independent of the central heating and decides himself when he start using warmth in his own home.

Views

All boilers are divided into some criteria. Below are the main categories of separation.

By type fuel

Gas

Different with economy and energy efficiency. The cost of using gas in this design of the unit is small compared to other sources of energy, and the efficiency is high.

Electric

In use, these boilers are much easier than gas. However, the cost of the design itself is higher. The heating of the water flow occurs at the expense of the Tan, the electrodes or induction elements. Of the disadvantages of using this type of equipment, it is worth highlighting the following positions:

1. High cost spent resources.
2. If, in addition to the warm floor, the radiators will be used in the house, it is worth noting that not all sorts of radiator systems will allow rational use thermal energy. In this case, the use of cast iron and steel batteries is not recommended. The best option will be the installation of bimetallic or aluminum radiators.
3. Constant power dependence. In the event of a power failure, the user can remain without heat source.
4. For equipment with a power consumed from 9 kW, a three-phase 380V network is required. In the case of its absence, it is necessary to obtain permission that is not always possible. This is especially true of the houses of the old building.

Solid fuel

The work of this type of boilers is ensured by solid fuel. Firewood, pallets, coal and other burning materials can be played as it. However, some disadvantages of such a category of equipment make it a less attractive heat source than a gas option:

1. For solid fuel boilers, complete chimneys should always be provided.
2. This option is performed exclusively in the outdoor performance, and large mass And dimensions make the user look for a separate room.
3. When using such equipment, it is necessary to have a supply of dry fuel.
4. It is necessary to constantly lay fuel in the furnace.
5. Dry fuel every year becomes only more expensive.

Diesel

The work of such an aggregate is carried out at the expense of diesel fuel. Autonomy independent work - Until a few months. There are also cons of the use of such an aggregate:

1. The user when installing this type of equipment will face the problem of searching for the appropriate room. The fact is that it should meet strict requirements.
2. Fuel thickening. This may occur if the coolant cools up to +5 degrees. To protect yourself from this fact, it is necessary to provide heat insulation of the pipeline and filters. Also, in order to avoid this problem, you can think over the heating of the system.
3. For liquid fuel, a special container is needed from plastic or steel.
4. Equipment must be constantly removed due to the constant formation of soot. If this is not done, then due to deposits will increase fuel consumption.
5. When working a diesel installation, strong noise appears.

Combined

Survived version of boiler equipment for a private house where the fuel supply is observed. This type of boilers has two fireboxes, allowing you to use one of the types of fuel, or one universal firebox with which you can use different kinds Heating resources. The main minus of such an installation is its high cost.

Separation by the method of placement

Allocate:

• Wall. This version of the equipment is installed on the wall and requires sufficient coating strength. For example, a fuel-concrete walls are able to withstand such loads. With these boilers, you can dump small and medium areas.
• Outdoor. This type of equipment is installed exclusively on the floor. The boiler has large sizes and is able to warm up huge areas.

According to the material of the heat exchanger

Allocate:

• With copper heat exchangers. Such an option of heating equipment has a compact size and a small weight. The inertia of the heating system in this case is small, which allows automation to instantly respond to user requests and respond to a change in the temperature regime in the rooms. This allows this unit to work in economical mode. However, such equipment requires a pump for a constant circulation process and to avoid overheating of water.
• With cast iron heat exchangers. All manufacturers in the production of boilers with such an element holds a secret composition of cast iron, because it determines all the necessary top Qualities. But it is worth noting that the most expensive brands of boilers with such elements are equipped with a gray cast iron, since it has a resistance to temperature drops and is a plastic material. From the positive characteristics of this type of boilers, high heat resistance and resistance to corrosion can be noted. The minuses include inertia and huge sizes.

• With a steel heat exchanger. About this category of boilers can be said as follows:

1. Low cost.
2. Easily leaving to restore.
3. Immunity to temperature drops.
4. It has large sizes.
5. Inertness.
6. DISTRIBUTY.

• Of of stainless steel . On sale occurs in condensation and diesel boilers, but not so often, since it has a high price indicator. It has the following characteristics:

1. Resistance to high temperatures.
2. Almost nonerine.
3. Anti-corrosion.
4. Durability.

• With a silicon heat exchanger. Boilers with such an element appeared relatively recently. It is a fusion of silumin and silicon and is used mainly in condensing aggregates in a cast form. The main property is the opposition to the aggressive qualities of condensate, which appears in huge quantities.

Separation of the type of combustion chamber

Allocate:

• With an open combustion chamber. Such heating equipment is characterized by work at the expense of natural traction. The air fence in such a boiler comes from the room, and the output of combustion products is carried out through the chimney.
• With a closed combustion chamber. This device uses forced thrust. It appears due to the installed fan, which removes combustion products through the coaxial pipe. Coaxial chimney It is a pipe in the pipe. The outer component performs the role of air tightening, and the internal exit of the spent material.

Such a boiler can be used in apartments without selection of a separate room.

Boilers with a closed combustion chamber are divided into two classes:

• Turbored. The device has either one or two turbines, due to which the air is discharged and the output of exhaust products. With this device, the burner power modulation is motion and adjusting the fan rotation intensity.
• Condensation. This type of aggregates is based on the accumulation of thermal energy obtained in the formation of condensate. They differ in economy and high productivity.

Separation by the number of contours

Allocate:

• Single-mounted. Such models are designed to heat the rooms.
• Double-circuit. This type of boilers are needed to provide home with warm and hot water. But in such aggregates you can meet several options for the execution of heat exchangers:

1. Double. This element consists of a primary and lamellar module. The primary module is a tube with ribs, responsible for heating water for the heating system; Plate - this is a set of plates, is responsible for water for DHW.
2. Bitermic. Such an element consists of two tubes inserted into each other. Interior Performs the function of heating water for the DHW, the outer is used for heating.

Torch

Allocate:

• Single-stage burner. Such a device is usually installed in non-volatile wall-mounted gas boilers with one contour. It performs the function of maintaining the temperature of the coolant.
• Two-stage device. Such a device has two modes of operation: 30 and 100% power. Gas consumption in such aggregates is reduced by smooth switching between operation modes. The device works without stopping. When water is heated to the required parameters, the power through automation is reduced to 30%.
• Modulation device. Power in such devices is regulated by microprocessor electronics from 10 to 100%. The intensity of the combustion process varies, depending on the parameters of the heating system.

Also boilers are non-volatile. Separately, we note this type of boilers. There are only on gas fuel. They differ in the absence of dependence on electricity. Instead, in such boilers, a mechanic is used that responds to changing the temperature parameters of the coolant.

Principle of operation

Gas equipment is both a source of hot water, and a cooled coolant receiver. Heated aqueous stream, coming out of gas equipment, circulates through a warm floor system. Its temperature gradually decreases, giving thermal energy pipes.

After the path traveled, the water returns. Its part of it is heated, the other is mixed with a new hot flow to obtain a consistency with the specified temperature parameters.

Safety requirements

Below are some software safety requirements. gas device in the House:

• For some types of gas equipment, it is necessary to provide a separate room.
• For room with gas equipment, a gas analyzer device is needed.
• In the room, the boiler house should not be flammable items.
• To accommodate the boiler, some free space on both sides of it is necessary.
• It is prohibited to the independent repair of gas equipment, as well as all additional security elements.

To install a mounted gas device, it is necessary to provide a fire based on which it will be installed.

Connection features

Before performing the strapping of the warm floor and gas equipment, it is necessary to lead the collector and the heat-mall system itself. Warm water floor can be connected to a column or other type of gas equipment in the following ways.

Collector option

The basis of this method is the strapping of the boiler, distributors and pipes. Location collective cabinet It should be convenient: here you need to bring a return and feed. But first it is necessary to install the shut-off reinforcement on collectors. It may have a thermometer in its composition to visualize the temperature regime.

Often it is necessary to turn off one contour for repair or preventive work without stopping the system. Therefore, it is highly recommended when choosing ready solution Base on the practicality of the purchased product.

For example, when buying a finished collector cabinet, it is better to give preference to brand brands, which already have the necessary cranes at all cabinet outputs.

Pipelines, cranes and collector systems They join each other with the help of fittings, and manifolds and the floor pipeline through special connectors, in the design of which there are clips, sleeves and nuts. If the diameters of the holes are not suitable for each other, the adapters are used. In this example, it is necessary to connect the return and feeding with pipelines and valves, and collectors with warm floor pipes. This is one of the most simple ways Waste floors.

Full collector-based system

In practice, the replacement of shut-off valves at the entrance and output to thermostatic adjustable cranes is often found. With the help of them, you can adjust the bandwidth thanks to the thermobalons installed in them. The three-way valve is responsible for mixing the return and feed, which is necessary to reduce the water temperature circulating along the warm floor, which can be laid on wooden beams.

The mixing pump will help organize the water flow fence with the minimum temperature, after which it will add it to the feed. To do this, the pump must be installed between the pipeline and the feed collector, and the third output is to connect with the return to the return pipe.

Scheme with a mixing valve

IN this variant Attaching the boiler and circulation systems instead of a mixing pump, a three-way mixing valve is used. To use this scheme the circulation of water flow must be good.

Installing this item should be performed at the output of the return from the collector. The pipes from the boiler unit are joined by collectors on the one hand, and on the other - the splitter for each of the collectors. The air vent is connected to the splitter device, and the drain crane is placed below.

Connection diagram with circulation pump

Mainly used to connect to central heating. Installation occurs on the return, so that there are more heat in the radiators. However, to reduce heat flux Often, installing such a pump is made on the feed.

Boilers for water warm floors do not differ from ordinary heating devicesused for modern radiator heating systems. To choose a warm water floor boiler, it should accurately calculate its power, it is probably the main difference from the boilers for the radiator system. The market offers a wide variety of this equipment, so you will not have any special problems with the search for the heating boiler. But, despite this, there is one convention that should be observed with the purchase.

Types of heating boilers - selection conditions

Although almost every boiler can be combined with a warm floor, there is one convention - it must be automatic. At the same time, electrical, gas, pellet and diesel units are introduced into the system. As for pellet and diesel, they should also be automatic. Therefore, it is not scary that they work on solid fuel. There are no conventions otherwise. Most importantly choose a reliable manufacturer who provides high-quality heating equipment.

Features of the electric boiler

Warm warm water floor electric boiler On average, 17% cheaper than radiator heating. Electricity is not cheap energy, so this percentage of savings will be several thousand rubles. Savings are achieved only due to the required temperature in the coolant.

The figure shows the principle of operation of the electric boiler:

The principle of operation of outdoor and wall boilers is the same. This article will consider wall variants.

The heating boiler consists of a tank. The heat carrier is introduced into it. Also in the tank there are beans. Tanes are two types:

1. Electrode (in this embodiment, electrodes are introduced instead of the TEN).
2. Water.

On the specified scheme in the tank, three tanks are mounted. At the entrance to the boiler installed a security group, which in its set has:

• Safety valve.
• Pressure meter.

No compulsory pressure sensor should have a pressure sensor. If it is not, then at the moment of lack of circulation, the coolant will be very overheated in the tank. This will lead to the fact that it will turn evaporate. At the top of the tank gradually forms emptiness and Tanes simply blown up.

The electric boiler is also equipped with a pump for circulating the coolant, an airfight, which works in automatic mode and expansion tank. When the heated water enters the boiler, it gradually warms up. In the picture, the heating process is specified different colors From blue to red. When the target temperature is achieved, the coolant is sent to the warm water floor system. According to this principle, the process of heating water for water heat floors in an electric boiler is carried out.

Video with demonstration The combination of an electric and solid fuel boiler for a warm floor:

The principle of operation of the gas boiler other. It can establish a combustion chamber of two types:

1. Open.
2. Closed.

In the case of a closed combustion chamber, ventilation will be only forced. This option has a more complex design, so we will consider it precisely that it is easier for you to deal with this issue. The figure shows the scheme of the gas boiler just such a plan.

Each unit assembly is placed in a special case. The boiler shown on the diagram is capable of measuring not only water warm floor, but also to warm warm water. Therefore, it has 5 conclusions at once.

• 1 Connection for connecting gas.
• 2 outputs for cold / hot water.
• 2 Output Feed / Floor Heating Furning.

In the attached instructions for the boiler, it is necessarily indicated for the purpose of each pipe, so it is important to examine it when connected.

A gas boiler also varies on other features. For example, it can be equipped with a heat exchanger and not equipped. If the boiler is planned to be used to heal the water of household needs, the heat exchanger is embedded in it. In the diagram, the boiler model is provided with him.

If the unit does not have a heat exchanger, then the water is heated by one camera as well as a heat heating coolant. Consider the work scheme of precisely such equipment.

• Cold water enters the extreme right tube, which is located below. In the same place is a security group.
• Next, there is a circulation pump, before which the tube from the expansion tank is removed.
• The temperature sensor is installed on this tube. In general, such sensors Gas boiler has three:
  1. On chimney for waste gases.
  2. For feed.
  3. On the return.
• After that, the coolant is sent to the heating element, and then sent to heating system Warm water floor.

Gas fittings are accommodated in the center of the boiler. It also has its own individual security unit. It monitors flame, gas pressure, waste gases. If problems arise during operation, the security group overlaps gas. The gas burner comes from this security unit. Exhaust gases are sent to chimney. The chimney can have a fan, as indicated on our scheme. It is thus the compulsory gases are carried out.

The main advantages of such boilers lies in the fact that the arrangement of the chimney pipe will not cause any difficulties. There is no need to remove the chimney pipe on the roof, you can simply pull it out onto the street (chimney pipe can be in a horizontal position). The coaxial tube is simultaneously entering the air, along the wide part of it, and the waste is less carried out. In contrast, for natural ventilation A high chimney pipe will be required, which will provide sufficient traction. It is displayed above the skate.

According to such a scheme and work is carried out gas installation.

What gas boiler is best for warm floors

On the market you can find a wide variety of (models) of gas boilers. Each of them has obvious differences on the principle of operation and the device. Optimal option For warm water floors there will be a condensing boiler.

In it, the coolant is heated not only at the expense of gas, but also due to heat, which is formed from water vapor in the process of burning fuel. As a result, the water floor temperature will not be very large. Although for such equipment it will be necessary to create additional conditions, it is more effective for heating the dwelling.

What boilers are impossible to combine with warm floors?

If you decide to install a solid fuel boiler, then in this case you will experience some difficulties when creating outdoor heating. This is due to the fact that the burning of fuel is impermanent and requires regular control, and after severe warming it is difficult to control necessary temperatures coolant. Therefore, experts do not recommend such equipment to use for warm floors, except that automation is introduced.

So, in this article, the basic options for boilers can be used for outdoor heating. We hope the photos and video at the end of the article will help this. nepical choice. If you have already fulfilled your choice, then share your experience by writing a comment on this article.
