You can make heated floors from a bathhouse stove. How to make a water heated floor in a bathhouse from a stove and boiler? Alternative and mixed heating options

Having heated floors in your home, you can already appreciate the benefits of such a space heating system. For those who have tried all the advantages of this heating method, it is quite natural to want to achieve the same effect in other objects associated with our everyday life. We can talk about heating here country house or consider a bathhouse as a heating object.

For us, the bathhouse is considered the standard of comfort, in which the main factor is warmth and comfort. Creating the necessary atmosphere inside a bathhouse is perhaps the main task that one has to face during the construction of a bathhouse. A warm water floor installed in a bathhouse can radically solve the heating problem. In addition, this heating option differs not only high efficiency and efficiency, but also improves the comfort of the bath room.

Warm floors in the bathhouse. Motives for this engineering solution

Not each of us has the idea that in a bathhouse literally every element of design and equipment plays its own specific role. The presence of a stove, thanks to which the steam room works, is not the main thing heating device in room. The main heating task in such rooms is usually performed by electric heating devices. The efficiency of such heating interior spaces in the bathhouse it is extremely small. Heating fairly large interior spaces using electricity is an expensive pleasure. A much more effective and practical option would be to install radiators or install heated floors for heating in the bathhouse.

Both options allow you to successfully connect to the main heating source. This can be a gas or solid fuel boiler equipped in a special way. The main thing in this case is to wisely choose a source of heating water that can circulate through the pipeline.

Typically for equipment autonomous heating The sauna uses an external tank fed from the main stove. The oven can be equipped with a water jacket. Some are trying to install a coil on the boiler in which the water will be heated.

On a note: Any heated water will have to pass through the manifold before entering the water circuit. Without this device, the installation of heated floors will not be complete.

Using various sources heat, you will certainly encounter the following problems:

your heated floor will only work when the solid fuel boiler or stove that powers the steam room is burning;
V winter time The water in such a water circuit will freeze.

There is nothing you can do about the first problem. If the bathhouse is used constantly, in commercial purposes, the warm floor will work normally and constantly. For those who use the bathhouse periodically, using a corrugated stainless pipe or for the pipeline will help avoid freezing of the system.

If there are no issues with heating radiators, a warm bath floor plays a more important role. In rooms where the interior spaces are heated mainly at the top due to the intake of hot air from the steam room and high humidity, the floor is often left without attention. However, each of us is very familiar with those not very pleasant sensations that are caused by cold tiles or eternally wet and slippery linoleum.

On a note: heated tiled floors dry within 10-15 minutes. The surface of tiles or linoleum used as flooring, are a breeding ground for fungus and bacteria. A dry heated floor prevents the spread of pathogenic formations.

After visiting the steam room, our body is in a relaxed and comfortable state. Cold floors clearly do not contribute to the duration of such pleasure. The sensations will be much more pleasant when the floor is the source of heat in the room. Warm air in this case it will evenly fill the internal space, creating comfortable temperature in the dressing room. In addition, heated floors prevent the accumulation of residual water on the floor. In rooms with high humidity, warm floors play the role of a compensator, drying out the air space.

By equipping your bathhouse with heated floors, you can completely abandon heating radiators. This will free up additional space and improve interior design premises.

Installation of a water floor in a bathhouse. Design Features

Having confirmed your desire to make your bathhouse more comfortable and cozy, get to work. Installing a heated floor in a bathhouse is not much different from traditional technology laying the water circuit in residential premises. The only condition is increased requirements for hydro and thermal insulation of the floor substrate. You choose for yourself what kind of flooring should be used for warm water floors in a bathhouse. Here the important role is played not so much by profitability as by the practical side of the issue.

The main question you have to decide is the following. Where should the heating floor be installed, in which section of the bath? There is no such need for a steam room. But for the washing compartment, dressing room and locker room, heated floors come in handy. The only difference will be in the type of flooring. For the washing room, tiles or porcelain stoneware are used. For the waiting room and locker room the best solution will become a laminate, parquet board or linoleum.

In practice they are used various options equipment of warm water floors in the bathhouse. The most common arrangement options are:

warm water floors laid on a wooden base;
laying a water circuit under a concrete screed;
use of polystyrene plates.

In each individual case, the choice depends largely on design features building. Large structures usually have concrete foundations. In smaller baths, especially this option, the floors have a wooden structure.

The main condition for the successful operation of warm water floors is an acceptable temperature of the coolant. The water entering the water circuit must have a temperature no higher than 55 0 C. What to do when the water in the coil, in the water jacket or in the tank is significantly higher. The collector is able to solve this problem, so there is no way to do without it. Due to mixing hot water with the waste coolant, an acceptable water temperature in the water circuit is achieved. Only with the addition of water will the warm floor meet the objectives.

We present to your attention schematic diagram heating water floors for a bath, connected to a heating device. The difference in this case will be in the source of heating the water. Everything else will be approximately the same.

We have already talked about the choice of pipes for the water circuit. With constant use of the bath ideal option you will be able to use metal-plastic, polyethylene or steel pipes. If a bathhouse is a rare occurrence for you, it is better to get by with a corrugated stainless pipe or polypropylene pipes. The layout of the water circuit pipe is selected depending on the configuration of the internal premises and their area.

As a rule, for a given heating system, two pipe laying schemes are chosen: “snail” or “snake”. For indoors small area, where one water circuit is used, the “snail” installation option looks preferable. This pipeline installation scheme will allow for uniform distribution of heat over the entire floor area. The “snake” scheme is used for rooms where it is planned to install several water circuits.

The water pipe should begin to be laid from the outer walls, gradually moving towards the center of the room. In this case, the optimal installation step must be observed. It will be better if you stop at a step of 30 cm. A step that is too small will cause a large consumption of material, but a step that is too large will create a stable feeling of the difference in temperature of the floor surface.

Not only water, but also antifreeze and other chemical solutions can be used as a coolant.

Important! Use for heating system ethylene glycol is dangerous to life and health due to the high toxicity of the substance. Ethylene glycol is the strongest poison!

Layer pie device

A characteristic feature of a bathhouse is high humidity. Warm floor systems are unpretentious in this regard. Properly equipped heated floors can work effectively in rooms with any humidity levels. In order for the entire system to work longer, as a rule, more attention is paid to waterproofing during installation. An additional waterproofing layer of thick polyethylene film laid on top of the water circuit pipes would be a reasonable solution.

When planning the installation of heated floors, first of all, you should take care of increasing the thermal insulation characteristics of the room itself. You should not neglect the technology of installing heated floors. It is important to follow a clear sequence of laying each element. Your heated floor should resemble layered cake, in which each layer plays its own specific technological role.

Typically, a layer cake consists of the following elements:

waterproofing layer (water barrier);
thermal insulation layer;
heat-reflecting element (foil);
water circuit pipes;
metal reinforcing mesh as a base concrete screed;
concrete mortar (for water pipes, the desired screed thickness is 50 mm.

For a bathhouse, installation of a concrete screed will be the best option. In addition, if the building is permanent and you are confident in the strength of the structure, installing the screed will not be difficult.

Important! When installing a screed in a bathhouse, some nuances should be taken into account. For a sink or shower, the screed must be made with a slight slope when planning installation drain pipe. The slope should not exceed 3-5 0. Otherwise, the circulation of coolant through the heating pipe will be disrupted.

After laying the pipes and reinforced mesh, beacons are made, located in such a way that when poured with concrete. The required slope was observed.

The minimum permissible thickness of the screed at its thinnest point is 50 mm. For those rooms where the rough surface is made without a slope, the thickness of the screed is accordingly different places will be different. Without taking this factor into account, you can end up with uneven heating of the floor in different places. Where the concrete layer is thicker, the floor will be less warm. Conversely, in thin areas of the screed the floor surface will be hot.

Better immediately on time preparatory work make a rough surface with a slope. A rough screed with a slope is made on top of the layer of waterproofing and thermal insulation. On top of which the water circuit is already mounted. Then everything is done in the same order. Another option to get out of this situation is as follows. When laying pipes, in those places where the screed is planned to be thicker, the pipeline is installed with a smaller pitch. Those. in those places where the screed is thicker, the number of turns of pipes increases. Due to this, heat transfer in this area increases.

Conclusion. Some information about the types of floor heating in a bathhouse

Having finished with the screed, you get an almost finished working surface of the heated floor. The remaining work will mainly be related to making the room comfortable and complete. Facial coverings largely determine the aesthetic characteristics of the room, however, we should not forget about the manufacturability of the coverings.

Usually used for baths ceramic tile or porcelain stoneware. Such surfaces are very practical in terms of cleaning, and at the same time they are an excellent waterproofing layer. The advantages of such a coating are durability, practicality and good thermal conductivity. Ceramic coatings used mainly for washrooms and rooms with a swimming pool.

Laminate, parquet board or linoleum are suitable for the dressing room and locker room.

In each individual case, you choose the type of coating yourself, taking into account the intensity of visiting the bathhouse and its capacity. For country house, at the dacha, laying linoleum on the floor would be an excellent solution. It is not recommended to use parquet or laminate in bathhouses where visits are periodic. Wooden surfaces can in the cold, unheated room start to deteriorate. The attractiveness of the room is lost and there is a high probability of mold spreading.

For the normal functioning of the heated floor in your bathhouse, you must carefully monitor the operation of the collector. Your comfort and coziness depends on its performance. During breaks between visits, bathhouses, water floors powered by stoves and solid fuel boilers must be drained.

Classmates

Fashionable novelty- heated floors - has successfully won a leading position among heating systems.

Some relied on them as the main source of heating, for others it additional element coziness and comfort.

Recently, somewhat unexpected options for using heated floors have appeared, which, despite their non-standard nature, fit very well into the environment and perform their task just as well. One of these unusual species heated floors are water heated floors in a bathhouse from a stove.

The tradition of arranging a bathhouse includes a wooden pouring floor. This option is not always possible. If the base of the bathhouse is made of concrete, then a completely different principle of water drainage is required and, accordingly, a different type of flooring. Tiles are most often used as the most suitable covering for wet rooms.

At the same time, the surface of the floor covered with tiles does not have the most comfortable properties - it is cold, which is unacceptable for a bathhouse. In addition, you have to spend more time and resources to heat the floor, which consists of a thick layer of concrete and tiles. The way out was the arrangement, powered by sauna stove. This solution immediately removes all questions - the floor becomes warm, it’s pleasant to walk on it barefoot, and there are no more uncomfortable sensations from being in the bathhouse.

From a technology point of view, making a water-heated floor from a sauna stove does not pose any great difficulties. The working body - with the coolant - is laid according to the usual pattern, the only exception being the method of pouring the screed, since a slight slope is required for the water to flow into the drainage pipe.

And also there are no questions in the organization mixing unit(if planned) and other elements of the system that make it possible to regulate and configure the operating mode. Power from a sauna stove is essentially power from a boiler, but with some reservations, which will be discussed in more detail.

Application

The use of water heated floors from a sauna stove is possible subject to availability concrete base, allowing you to fill the screed when installing the contours.

Therefore, the most practical option is with a concrete screed and tiles as a floor covering, which is what we are considering.

Additionally, using underfloor heating in a break room where the temperature usually doesn't rise too high will help equalize the heating levels between the floor and walls. Concrete floors are difficult to heat up and absorb a large number of thermal energy, causing the room temperature to become less stable and heating is not maintained for long. The use of heated floors significantly improves the situation, since in addition to heating the floor, it is provided with high-quality insulation.

Advantages and disadvantages

Water heated floor in the bathhouse from the stove - complex design, which has its own advantages and disadvantages.

Advantages of water heated floors:

leveling temperature regime premises, increasing the comfort and coziness of visiting the bathhouse;
the room is heated through two channels - directly from the stove and across the entire surface of the floor, which increases the intensity of heat exchange and reduces the time for preparing the bath;
heating of the room is uniform, without cold spots or zones;
the screed has high thermal inertia, accumulating heat in its thickness and releasing it into the interior of the bathhouse for quite a long time;
it is possible to use a sauna stove as a source of coolant, without the use of additional devices for water preparation.

Minuses:

complexity installation work, the need to use expensive equipment;
complexity ;
laying a water-heated floor pie increases the surface level, lowering the height of the ceilings;
the need to re-equip the furnace;
the need to organize high-quality drainage of water from the system to prevent freezing of residual water and destruction of pipelines or mechanisms.

All the advantages and disadvantages are basically common to water heated floors.

Kinds

Exist different designs water heated floor:

Concrete screed. Heated floor pipes are filled with a layer of concrete, which reliably protects them from destruction and makes contact with the floor surface as dense as possible. This method is most effective when used floor tiles. There is practically no loss of thermal energy.
Layered method. Applicable in the absence solid foundation, capable of bearing the load of the weight of the concrete screed. In this case, the underfloor heating pipes are laid directly on the base, covered with a layer of durable protective coating and a finishing floor is equipped. This technique is less effective due to weak contact of the pipes with the finishing surface; in addition, there are insulating layers that weaken the operation of the system.

Using the flat method is a forced option, but it is common because concrete floors or not all buildings have foundations.

There are three main types of heated floors:

Rack and pinion system. The pipes are installed between wooden strips that serve as limiters and clamps. The difficulty of installation is that all the slats have to be made independently.
Modular system. The pipes are fixed between bosses - special protrusions on the mats. Installation of such a system is simple and quick - you just need to lay out mats on the floor and lay pipes between the bosses.
Polystyrene system. Similar to nothing modular system, but instead of mats, polystyrene slabs with recesses for laying pipes are used. Used on non-insulated bases to separate underfloor heating pipes from cold subfloors.

Attention! All three methods are used on wooden subfloors and are not used in wet areas. Such methods are not suitable for a bath due to poor moisture protection.

Principle of operation

The piping system, embedded in a concrete screed, receives power from a stone furnace, converted to allow parallel heating of the coolant. When the stove is ignited, heating of the floor heating system begins, which by the time the bath is ready is in full working order. The circulation of the coolant is carried out with the help of the mixing unit. Warm pipes they heat the concrete screed and the floor surface, which radiates energy into the room.

Device

The water heated floor system consists of several units:

Heated floor contours. These are pipelines, evenly laid at a short distance from each other on the floor and filled with concrete screed. To reduce the load on the circulation pump, these pipes are divided into several sections of equal length, called contours or loops. They are the main working body of a water heated floor, producing thermal energy into the screed and onto the floor surface.
Mixing unit. Important element underfloor heating systems, providing adjustment, configuration and automatic maintenance operating temperature warm floor. Since the sauna stove does not have the ability to produce water desired temperature, the coolant can be very hot, almost boiling. It is impossible to direct such a flow into the circuits, so a mixing unit is used to make a mixture of the cooled return flow with the hot forward flow. Without such a knot, it will become impossible to walk on the floor.
Heat exchanger. A device in which the coolant is heated from the furnace. In practice, this is a container or register made of pipes filled with coolant. It is located in the upper part of the stove, above the firebox. If the stove is equipped with a water tank, then the firebox is connected with pipes containing coolant.

Important! High-quality operation of the system is based on the reliability of installation and connection of the circuit pipes. Elements that are visible can be easily repaired, but pipes hidden in concrete are very difficult to repair and require serious work.

The need for separate heating of water for washing and coolant is that when using ordinary water in a heated floor system it is necessary to be able to drain it completely, which is very difficult to achieve. Small amounts of water left in the pipes may freeze and cause them to burst. Therefore, you will either have to constantly heat the bath, which is uneconomical, or use antifreeze, which cannot be mixed with water; a separate heating line will be required.

Bake

To power the heated floors in the bathhouse from the stove, you will need to prepare a separate heating fluid heating line. This can be done with your own hands.

To do this, you need a heat exchanger, which must be placed in the heating zone of the firebox.

Depending on the original design of the furnace, this is done either by installing a heat exchanger above the firebox, or by piping the firebox with a pipe system. In this case, the volume of coolant becomes too small to fully supply the system, so to increase it you will need an additional tank, usually located next to the furnace.

Installation

Stages of installation of a water heated floor:

Preparing the base, cleaning from dirt, inspecting the surface.
If there are flaws - cracks, depressions, etc. - a thin leveling screed is poured.
Double layer of waterproofing. The surface of the concrete is covered with a layer of hot bitumen, on which roofing felt is laid. The strips are overlapped by at least 10 cm. After this, bitumen and roofing felt are applied again.
Laying thermal insulation. Hard and moisture-proof insulation is used - EPPS, penoplex, etc. The insulation layer must be at least 5 cm, laying is done as tightly as possible, without gaps.
On the surface of the insulation mounting grid is laid for fixing pipelines.
Along the perimeter of the walls damper tape is installed, compensating for thermal expansion of the screed.
Laying a pipe system (circuits) in a certain order. Fixation with clamps on the mounting grid.
Connecting pipes to, test run of the system, performance check, pressure testing.
Laying drainage pipes for discharging used water(where necessary), connecting drain funnels.
Filling the screed. During this action, the underfloor heating pipes must be under pressure.
After the screed has hardened, the tiles are laid. In this case, a slight slope towards the drain holes should be provided to organize the drainage of used water.

conclusions

All work on installation and installation of equipment can be carried out independently, without the involvement of outside specialists. During work, you should act as carefully as possible, avoid making mistakes or sloppy actions, so that you do not have to redo your work later, since this will require a lot of effort and time.

In contact with

Warm air tends to rise upward by convection currents. Therefore, even in the bathhouse, the floors are often cold. The contrast between hot air and an icy floor is a sure way to catch a cold.

Most often, bathhouses have electric floors (): this is simpler, and since the bathhouse is not used every day, the energy consumption is not too large ().

If you have a stove, you can try to make a water circuit from it. How to make it in a sauna from a stove?

When a stove is used instead of a boiler (), a heat exchanger is placed above the firebox.

For this purpose, you can use a tank or a register (a grid of pipes). Wiring is made from it throughout the entire building.

The device from the stove in the bathhouse requires a circulation pump (), otherwise the cooled coolant will not flow back into the heat exchanger.

You can do without a pump only in one case: if you place the stove below floor level. Then the system will be able to operate on natural circulation.

For natural circulation, it is necessary to increase the diameter of the pipes (at least 2.4 centimeters; usually heated floors are laid metal-plastic pipe 1.6). But, given the large length of the heated floor circuit, circulation without a pump, even with thick pipes (), will be slow and ineffective.

The scheme of a heated floor in a bathhouse from a stove (not only in a bathhouse, in a house too) looks more complicated than a heating system with radiators. Modern boilers can adjust the heating temperature, but stoves cannot.

The temperature of the heated floor should not exceed 40 degrees (optimally 30), and on the stove it will heat up to a boil. Therefore, in addition to the pump, you will also need a mixing unit.

When installing several circuits for different rooms a collector () is installed between the boiler and the floor. Valves with thermal heads, two- or three-way taps are connected to it. If possible, servo drive. These devices will allow you to regulate the operation of the floor.

Because place a heat exchanger in the oven big size, as a rule, is impossible; a battery tank is installed next to it and connected to the heat exchanger with metal pipes.

The volume of the tank depends on the area of the heated room and the heat output of the stove, but not less than 100 liters. The container serves as a buffer: constant water exchange between the storage tank and the boiler prevents the coolant from boiling.

Disadvantages and features of the water circuit in the bathhouse

The bathhouse is used inconsistently. On winter period the water will have to be drained, because... otherwise it will freeze, which will cause pipes to burst. Or you need to heat it constantly in winter.

But then wood heating will cost more than an electric boiler or electric floor. Therefore, if you plan to use the bathhouse all year round, antifreeze should be used instead of water. In this case, it will no longer be possible to combine heating and domestic hot water.

The second disadvantage of such a system is that most of the heat is spent heating the battery tank. For its main purpose (heating the steam room and washing room), the stove does not work efficiently, and the floor itself heats up more slowly than under standard conditions.

If you plan to lay a heated floor in a bathhouse from a stove in several rooms (steam room, dressing room, relaxation room, shower), the volume of coolant will be larger, and this will additionally increase the warm-up time.

The classic design, in which water goes into the pit through cracks in the floor, cannot be installed: the insulation will get wet, and when wet it is not functional.

When installing heated floors, the drainage is organized differently: they make a slope and dig a well for water in the lowest corner of the room. A pipe is built into the wall of the well, which drains water into a drainage ditch or simply onto the street.

For the same reason, it is recommended to lay a warm floor in wet rooms of a bathhouse with a screed () under the tiles: to make it absolutely airtight plank covering impossible.

Wooden flooring can be laid in the dressing room and rest room. But it should be remembered that wood is a good heat insulator. This means that it will take even more time and energy to fully warm up the floor.

Installation of a water floor

Pie () for the floor in the bathhouse is laid in the same way as in the house:

waterproofing;
insulation;
reflective foil;
pipes (for water floors, the optimal installation pattern is a spiral, since it heats the floor evenly);
screed with a slope towards the drain and finishing coating.

If the installation is carried out on the ground, before laying the waterproofing you need to pour a sand and gravel cushion or a layer of expanded clay.

In dry rooms you can do without a screed:

choose as insulation profile mats(), lay the pipes in the channels, and on top - the finishing coating;
use chipboards with milled channels;
lay pipes between the joists.

conclusions

How advisable it is to make a heated floor from a stove in a bathhouse is up to the owner to decide.

Many homeowners resort to compromise options: they install electric floors in the locker room and rest room, and where there is a stove (steam room, wash room) they limit themselves to a simple plank floor, which is rarely truly icy.

Video about a warm water field in a bathhouse.

In the past, heating of the bathhouse was carried out only by heater stoves. The floors were made of wood, and sometimes they were earthen. Accordingly, in such baths there was no talk of heated floors. Why didn’t they think of setting up bathhouses earlier? warm floors unknown. But as for our time, today there are many technologies that make it possible to organize underfloor heating. This article will discuss manufacturing methods underfloor heating, and you will also learn how to make a heated floor in a bathhouse.

To equip the floor with heating from the stove, you will need to install a metal jacket. Her appearance can be described as follows: a central pipe is laid, and branches go from it in different directions, forming a skeleton. Each branch is connected by pipes, forming closed system. This structure is installed inside the furnace directly above the firebox. Water circulation can be natural or forced (a circulation pump is used).

The shirt, to some extent, plays the role of a cauldron. The coolant is heated in it and supplied through a system of pipes laid in the floor.

In addition to arranging the shirt, you will need a thermal (buffer) tank. Its installation is carried out outside the furnace, and is connected to the jacket metal pipe. The volume of the buffer tank can be from 100 to 1 thousand liters, it is calculated based on the boiler power. If the heating circuits contain coolant with a volume of more than 100 liters, then there is an option for arrangement without a thermal tank. If you want to create natural circulation of water, then mount the buffer tank and the jacket at the same level. Circulation will be carried out due to the difference in coolant temperature.

What is the key role of the buffer capacity? Its presence helps prevent water from boiling in the system. It is for this reason that the container should not contain less than 100 liters of water. Even if the existing boiler has low power, and the heat capacity is only 20 liters, then when the boiling point of water reaches 100°C, the coolant will boil in 5 minutes. For this reason, the buffer capacity is an integral part of the entire system.

If the jacket is installed below the jacket level, natural circulation will not be possible. It will be necessary to install a circulation pump.

Organizing a warm floor with natural circulation will be problematic, because you will need to move the boiler room outside the bathhouse. Why? Since the heat exchanger must be below the floor level of the bathhouse. For this reason, it is easier to make a warm floor from a stone stove with forced movement of the coolant, namely with the installation circulation pump. It is installed on the outlet where the coolant is supplied to the pipe circuits from the buffer tank. Thus, the water circulates, where the cooled water is sent back to the heat capacity, warmed up and returned to the heating circuit.

Such warm floors can also be made with natural circulation. However, the pipe system laid in the floor must be above the level of the heat exchanger, and the pipes must be at least Ø 1″ (2.4 cm). As a result, it turns out that heat will be supplied to the bathhouse through a pipe that is brought to the top. The effectiveness of this heating method will depend entirely on the size of the oven.

In principle, such technology can be implemented in a bathhouse. But it is important to understand that it will take a large amount of heat from fuel combustion. As a result, achieve high temperature indoors will be unrealistic.

Other methods for arranging heated floors in a bathhouse

There are more modern and equally effective technologies for installing heated floors. For example, using a gas or electric boiler. The coolant will also be water. There is an option for installing heated floors using electricity. Electric heated floor has high degree protection, as a result, it does not pose any danger to people. This method is used to heat the floor even in a washing room.

When arranging the floor in a bathhouse with electric heating, it is important to ground it. Without it, it is prohibited to put electric heating into operation.

When laying an electrical cable or mat in a screed, care must be taken to ensure that under no circumstances does moisture penetrate there. The service life of an electric heated floor can reach 30 years. This is possible if you follow the technology of its installation.

Polymers, which act as an insulator for electrical heating, are destroyed only due to the influence of sunlight on them.

If you are building a bathhouse from scratch, then you can ensure a relatively warm floor by laying wood on it. If you want to use a hydronic floor heating system with forced circulation, then the ideal option would be to pour a concrete screed. Ceramic tiles will be laid on top of it. Please note that the heating pie, which includes a screed, should not be a single part of the foundation. Why? When heated, concrete tends to expand. And if the heated floor screed is made integral with the foundation, when it expands, destructive pressure will be exerted.

When installing a screed, a damper tape is laid around the perimeter of the room. It will compensate for thermal expansion.

Some, in order to save money, decide not to lay thermal circuits in the floor of the bathhouse. They place a cushion of sawdust or polystyrene foam and a layer of waterproofing between the joists. While these floors will certainly be warmer, there is a downside to this. There is always high humidity in the bathhouse. Therefore, there is a high probability that after a while moisture will begin to penetrate through the waterproofing and between the floor boards into the insulation layer. Because of high humidity, the moisture that has dropped into the insulation will remain there. As a result, this will cause the boards to rot. It will take a lot of money to restore the floors. Therefore, in most cases, it is better to pay immediately and build reliable floor heating in the bathhouse at the beginning of its construction.

In order for the floors to heat up as quickly as possible, you need to take care high-quality thermal insulation. As a rule, it is laid under a rough screed or directly under a heating circuit. Regardless of the choice of floor heating method, the heating cake has the following design:

Thermal insulation.
Thermal reflective material.
Heating circuit (pipes, electrical cable, mats, etc.).
Poppy mesh.
Finishing screed and finishing floor material.

Where to choose

So, which method of heating bath floors is better? To answer this question, it is enough to compare systems from an economical angle. As practice shows, it is quite expensive to install an electric heated floor over the entire area of the bathhouse. You will especially feel this when you have to pay for electricity. If we start only from this factor, then the thermal energy of a sauna stove can be used for a steam room, and in other rooms it can serve as an additional source of heat electric heating. This floor can be turned on as needed.

When installing floor heating using only a jacket and a buffer tank, constant heating is required in winter. Otherwise, the system will simply freeze. Plus, the costs of purchasing firewood or gas are added to this.

So, to summarize, each of the systems described in this article is relevant and has the right to life. So, organizing heating from a stove, electricity or gas boiler quite real. It is very important to follow the installation rules. In this case, the underfloor heating will last for many years in full working order. We will be interested to know how you installed heated floors in your bathhouse. If you know how to properly carry out this or that work, then write comments at the end of this article. Perhaps you can help other craftsmen install a heated floor with their own hands, without the involvement of qualified specialists.

Below is a video from which you can learn the features of making a heated floor in a bathhouse based on infrared heating:

Home improvement floor systems heating, as a rule, allows us to warm the rooms of our apartments. But hidden heating units can also be used to create the most comfortable conditions in places such as steam rooms, saunas and baths. And how to make a heated floor in a bathhouse from a stove, the diagram in which plays an unimportant role, you will learn from our article.

System Features

Due to the fact that not a boiler, but a stove will be used as a heating installation, a heat exchanger should be installed on top, above the firebox. As a rule, for these purposes, the most common tank made of stainless steel or any other metal that is not prone to corrosion upon contact with moisture is used. You can also take a register from pipes. There is no fundamental difference in this. From the heat exchanger for the heated floor installed above the stove, a pipeline is laid to those rooms where it is necessary.

In order for the “spent” coolant to be able to return to the exchanger again, a small circulation system will also be required. pumping unit. Without it, the structure will be able to fully function, provided that the stove is located below the level of the floor surface. In addition, pipes of a non-standard diametrical size for such heating blocks will also be required. So, to install a hidden heating block that will be powered from the furnace, you need to purchase Ø24 mm pipes, whereas when laying a pipeline under standard conditions, a Ø16 mm pipe is used.

The main feature of a stove floor heating system is the impossibility of adjusting the temperature regime.

The recommended temperature of the structure in such conditions is 40°C, while the furnace will supply almost boiling water into the main line, which is not acceptable for the coolant. Therefore, in such cases, it is advisable to equip the system with a mixing block, through which hot water from the furnace and the cooled source from the “return” will be mixed.

Since it is not possible to install a large heat exchanger in the furnace, an accumulator tank should be installed near it, which is connected to the heat exchanger via steel pipes.

Pros and cons of the design

Before answering the question, how to make from a stove water heating, let's look at the advantages and disadvantages of such a setup.

So let's start with the positives:

absence electromagnetic radiation how this happens when arranging a room with electric floors;
environmental Safety;
possibility of creating camphor temperature conditions in the steam room;
cost-effectiveness (not only does the installation of electric floors cost several times more, but you also have to pay considerable monthly electricity bills);
eliminating the appearance of fungal infections and mold;
preventing the appearance of cold drafts, since the energy from heating element will begin its smooth upward movement, uniformly heating the area of the entire steam room.

As for the disadvantages, these include:

The need to drain the heat source from the system in the winter, which will prevent pipeline rupture due to an increase in the volume of frozen water.
A considerable amount of energy is spent heating the battery tank, which causes a decrease in the efficiency of the furnace.
Simultaneous heating of several rooms, for example, steam room, dressing room, shower room, etc. Large volumes of coolant are required, which significantly increases the time for its complete heating.
Inability to install leaking floors in the bath room. As a rule, many baths are equipped with such systems, which simplifies draining excess liquid. In the case of heated floors, this is absolutely impossible to do, because all the insulation and thermal insulation materials will be completely wet and will not be able to fully fulfill their purpose.

Tips for arranging floor heating blocks in a bathhouse

To organize an efficiently operating heating unit in a steam room, it is necessary to adhere to several important recommendations that were proposed by experienced specialists working in this field of activity.

This is what the “pie” of a water heated floor looks like

Concrete screed

A concrete screed base is the best option for floor finishing of a bathhouse, because it allows you to significantly save on materials, but at the same time has high moisture resistance due to the use of cement.

However, such a floor can only be used after the solution has completely hardened. As a rule, this can take from two to four weeks, it all depends on the conditions in the room itself. In addition, if the line is damaged, it is extremely difficult to localize the leak, which requires complete dismantling of the screed.

Polystyrene boards for thermal insulation

It is best to use special polystyrene-based boards as a thermal insulation material. They are equipped with a reflective metallized layer and have special internal grooves for easy media placement.

Installation of communications in a wooden floor

Installation of a sauna stove on a wooden floor and installation of a main line in a wooden floor structure is also possible. But in this case, it is necessary to carry out an accurate calculation, with the help of which it will be possible to determine the location of the holes in the joists for laying the coolant. But as far as maintainability is concerned, such systems are much better than those installed in a concrete tie structure.

Stages of installing a water heated floor

The efficiency of its operation and, accordingly, the comfort in the bathhouse depends on how correctly and accurately you can assemble the water heating unit.

So, the floor heating installation in the bathhouse looks like this:

the first layer is a rough screed, thanks to which you can eliminate possible distortions and unevenness of the decorative floor covering;
Next comes a waterproofing sheet, which prevents condensation from accumulating during operation of the element;
lay on top of the waterproofing thermal insulation material, which will allow all the energy to be directed into the heated room, eliminating all heat loss;
the fourth stage is laying a reinforcing mesh that protects the layer of insulating fabric;
Next you need to install a metallized substrate, which will reflect energy into the room without letting it pass into the walls and interfloor ceilings;
the sixth stage is laying the main line, which is best laid according to the “Snail” pattern, due to which the heating of the surface is more uniform

a finishing screed is poured over the pipeline with a slight slope towards the drain hole;
The finishing touch is laying the decorative covering.

As you can see, floor heating from a stove is not difficult to arrange in a bathhouse. This method will allow you to save money on the purchase of a heating boiler and energy costs. As a result, the bathhouse will have a favorable microclimate and a comfortable floor.
