Heating a bathhouse from the home heating system
If the central heating system of the house has sufficient power, the auxiliary rooms of the bathhouse can be heated using it.
To do this, heat-insulated pipes are laid from the home heating system to the bathhouse, to which heating radiators for the auxiliary rooms of the bathhouse are connected. In this case, the stove-heater can only be used to heat the steam or washing section of the bath, if necessary. If the distance from the water heating boiler of a residential building to the bathhouse is small, then heat loss with such a heating system can be minimal. In addition, the presence of an independent external heating system will allow you to maintain the optimal temperature in the bathhouse during the winter. This is required to prevent freezing of water supply and sewerage pipes, as well as the bathhouse itself. The combination of heating systems of a residential building and a bathhouse in this case can be of an auxiliary, backup nature.
Heater type - open and closed
A standard electric stove requires an open heater type. In this case, the stones are located between the heating elements and are not closed from above. This method of producing steam is the simplest, but has disadvantages. Stones located on top heat up less than those located below. The result is low quality steam.
In a closed heater, the stones heat up much better and more evenly. Thanks to this, such a stove produces good, finely dispersed steam, optimal for a Russian bath. But this has its own problems - to obtain high-quality steam, you need strong heating of a sufficiently large number of stones, which means high power of the electric furnace. But such an electric heater is not suitable for a small bathhouse.
How to heat water in a bathhouse from a stove
You can organize heating of water in a bathhouse with a brick stove using a cast-iron stove above it. The hot water tank is installed directly on the stove itself, it can be round or square, with water supplied to fill the tank from the incoming water pipe and hot water drawn through the tap.
You can heat water without connecting water pipes to it. In this case, for each heating of the steam room, reserves of cold water should be made in the dressing room, and the water tank should be filled manually before lighting the stove.
This method of heating water is quite simple, but it has significant disadvantages:
- labor intensity of preparation;
- increased humidity from boiling during prolonged heating;
- risk of getting burned on the heated walls of the oven and tank.
You can heat water from the stove in different ways. This depends on the type of stove itself, the presence of water pipes connected to the bathhouse, the financial capabilities of the owner and his desire to make certain efforts.
Heating water in a bathhouse through a heat exchanger
The best option for heating water in a bathhouse is the heating method using a heat exchanger. There are several ways to make a structure for heating through a heat exchanger.
In a brick oven, the heat exchanger can be a multi-section cast iron battery or a register welded from a thick-walled steel pipe. The heat exchanger is mounted in a special furnace cavity with separate inlet and outlet valves. When the stove heats up, the water in the exchanger becomes hot and is dispensed through the water tap as needed.
In the case of a metal stove, everything is much simpler. In order to heat water with such a furnace, several types of heat exchangers are used:
- external heat exchanger (located in close proximity to the firebox or above it);
- internal heat exchanger (located in the firebox itself);
- heat exchanger on the flue pipe (located on the chimney pipe above the tank with stones).
Advice! The water tank with heat exchanger and the hanging tank can be used simultaneously. This combination makes it possible to heat an almost unlimited amount of hot water.
Water heater for a bath on a pipe
To heat the water in the bathhouse, tanks located on the pipe are used. They can have a rectangular, square or cylindrical shape and are rigidly mounted on the stove chimney pipe. Pipe water heaters are universal; they are used in wood stoves and gas boilers. The water tanks on the pipe are small (optimally up to 80 liters) and can fit even into a small bathhouse.
The tanks on the chimney pipe are located high enough above the stove, so there is no need to pump up hot water - it simply flows by gravity. The water tank can occupy the entire length of the pipe, from the heater itself to the ceiling. This increases the hot water production area and the efficiency of the heat exchanger.
The design of the water tank on the pipe must have reinforced fastening to the stove and the exhaust chimney on the ceiling, since a tank filled with hot water is heavy. The usual soft fastening of the chimney in the ceiling area is not suitable here, so for fastening it is best to use special chimney brackets.
Built-in or attached water tank to the stove
Another option for heating water is a water tank built into the stove structure or located on the side of it.
A built-in tank is a rather complex structure that must be thought out before laying a brick oven. The optimal solution here could be a special niche or recess in the furnace to accommodate a water tank with inlet and outlet valves and hot water intakes. It should be noted that for such a design the tank must be durable (preferably made of stainless steel), with thick walls and double welded seams. Otherwise, if a leak is detected, the entire structure of the furnace will need to be disassembled.
A water tank attached to the side of the stove is a less energy-intensive way to heat water. It is often used in bathhouses with metal stoves, which are supplied with water tanks. Since the steel or cast iron body of the furnace has good thermal conductivity, the water in the tank heats up quickly, and if necessary, the tank can be easily refilled (centrally or manually).
Hot water in the bathhouse from the stove (the layout of the water tank is shown below) is a simple task for a good owner.
Recommendations for use
The instructions tell you how to connect the heat exchanger to the sauna tank. When purchasing, make sure all items work. To do this, follow the recommendations:
- Check the mobility of fasteners, which may cause damage to parts that regulate air exhaust from a room with high humidity and temperature.
- It is necessary to buy a heat exchanger for the furnace with heat-resistant parts.
- The container should be small and contain the amount of water heated using a heat exchanger in two hours.
- Purchasing elements separately requires correct compatibility in a single design according to technical parameters.
- The heat exchanger for a sauna stove should use no more than 15 percent of the energy of the power of the entire structure.
Operating a heat exchanger in a sauna stove involves regularly inspecting the tank for fullness and regulating the temperature of the outlet liquid. When installed correctly, the device does not affect the chimney. Fire-resistant materials ensure safety during operation.
System Features
When installing a heated water floor in a bathhouse powered by a wood-burning stove, there is no need to install a boiler. However, a heat exchanger needs to be built above the firebox. Any stainless steel tank that is not prone to corrosion is suitable for this. A circuit extends from it into the room where the heated floor will be installed.
To return the waste liquid to the tank, you will need to install a small pump. Without it, the design will only work when the stove is located below the level of the floor covering. The diameter of the pipe with this scheme should be taken equal to 16 mm; the usual 24 mm ones will not work.
The main feature of the stove floor design is the inability to adjust the temperature level. The recommended temperature of heated floors in the bathhouse is 40 degrees, but the heat carrier from the stove will heat up to boiling water.
Video
Therefore, it is necessary to make a mixing block in which hot water will be mixed with already used water, thereby reaching the desired temperature level.
Since it is not possible to install a large container in the furnace, you can place a battery tank near it and stretch steel pipes from it to the heat exchanger.
How and how to connect the external tank to the heat exchanger
Heat exchangers for baths are used in construction from heat-resistant materials. All parts that interact with the stove heat up. Therefore, the pipes are made of stainless steel. Cast iron parts are susceptible to corrosion and are unwise to use. Plastic pipelines or flexible hoses can be used when installing a bath structure with your own hands.
Modern technologies help to choose a variety of materials for construction. The main requirement is heat resistance. Tangit, paronite for seals and connections at joints and turns will be an excellent solution when building a sauna stove.
The drain valve must be connected to a water tank. Draining is done to prevent water from freezing in cold weather, which will burst the pipes. Preservation of the system for the winter will require preventive actions to maintain the functionality of the heat exchanger in the bathhouse.
What makes this type of floor heating system unique?
Thermal energy tends to the top, so in the bathhouse the air is distributed in layers - cold at the bottom, hot at the ceiling, most comfortable in the center. Therefore, the floor in the bathhouse is always cold, which cannot but cause discomfort. This problem is especially relevant for baths with ceramic tiles on the floor. This finishing material is beautiful, but has a cold surface. But there is a way out - to mount the system in the floor, the coolant in which will be heated by the stove.
Instead of a boiler, the heating unit will be a furnace, so a heat exchanger is installed above the firebox - a tank made of stainless steel or other metal that is not subject to corrosion. The pipeline from the heat exchanger is carried out to the premises where the “warm floor” will be installed.
Sauna stove with heat exchanger
To return cooled water back to the tank, you need to install a circulation pump. It is impossible to refuse it, since the stove is not installed below floor level. It is recommended to choose a pipe diameter of 24, while for installation of “warm floors” in residential premises, contours of 16 diameter are chosen. The main feature of a water system powered by a furnace is that the temperature of the coolant inside cannot be adjusted.
For a “warm floor” system, a comfortable coolant temperature is 40 degrees. Very hot water, almost boiling water, will be supplied to the system from the stove, which is unacceptable. Therefore, it will be necessary to install a mixing unit, where the cooled coolant will flow into the hot water. It is advisable to install a “warm floor” from the stove in all rooms of the bathhouse.
Cake of water “warm floor”
Pipeline installation
We have already mentioned that for pipelines it is better to use pipes with a diameter of 3/4″; this diameter is most often used in all heating systems and is suitable in all respects for a bathhouse heat exchanger.
Pipe diameter 3/4″
Pipes can be metal or plastic. You can also use flexible corrugated hoses, but you need to keep in mind that they have a significantly smaller nominal diameter, and this negatively affects the speed of water flow.
Let's give some tips on installing pipelines.
- Try to reduce the length of the pipelines as much as possible; do not make many turns or bends in the pipe. Your task is to create the most favorable conditions for water circulation.
- When using plastic pipes, do not allow them to overheat at the junction with the heat exchangers. The presence of water inside will prevent their complete breakthrough due to loss of strength caused by heating, but deformation is possible.
- Don't forget to place the drain valve in the lowest place. If the bathhouse is not used for a long time, then in winter you need to drain all the water from the system.
- When connecting pipelines, provide for the possibility of dismantling them to perform repair or routine maintenance work.
- Try to keep the length of horizontal sections of the pipeline to a minimum. Install all such sections at an angle of at least 10°. Such measures have a positive effect on the speed of water flow.
Installation of a water floor from a sauna stove
Initially, water heated floors were not intended for installation in a bathhouse. Therefore, when laying such a “pie” in a bathhouse, it is required to equip it with additional elements.
The installation of a water heated floor from a sauna stove includes several components:
The heated floor contour is the main working element, which is laid evenly across the entire floor of the room with a certain pitch, filled with a concrete-cement mixture screed. You should choose the right pipe model; in this situation, not every one will be suitable. It is best to use copper, metal-plastic or stainless steel corrugations. However, many people prefer cross-linked polyethylene pipes with increased heat resistance, with a service life of at least 30 years, or polypropylene pipes, with a warranty period of at least 50 years.
The mixing unit is an important part of the system, since the stove is not capable of heating the coolant to the required level. It heats the water almost to the boiling stage; in this state it cannot be supplied to the circuit. Therefore, a mixing unit is needed, in which boiling water will be mixed with the waste coolant to the required 40 degrees, and in this form it will be sent into the pipeline. It is used to regulate, configure and automatically maintain the temperature level of the heated floor in the desired mode.
Heat exchanger - a container, coil or register located above the firebox, where the liquid from the furnace is heated. When using antifreeze as a coolant, you will need to equip a separate heat exchanger, then the antifreeze will not be able to get into the washing water.
A circulation pump is necessary to ensure that the coolant is evenly distributed and moves through the pipeline. Without it, a warm water floor cannot function, as it provides the circuit with additional pressure for fluid circulation. When selecting the pump power yourself, you need to take into account the area of the heated room; the larger it is, the higher its performance should be.
To reduce the load on the pump, it is recommended to divide the pipeline into several parts of equal length.
Drainage is necessary to remove excess liquid from the steam room and washing room of the bathhouse. You can equip it with your own hands, taking into account the following two points: by constructing a water outlet - a drainage hole, through which the water will flow into the pipe and be discharged into the sewer pit; fill the screed with a slope in the direction of the drain hole - then all the water will flow towards the slope.
Source of water supply
A water source is rarely constructed exclusively for a bathhouse. In the absence of a centralized water supply system, a water supply system is needed primarily for residential buildings and household needs. Therefore, as a rule, a bath water supply system is built into an existing private water supply system. For this purpose, a collector distribution line is installed, where the pipe is routed to the bathhouse building.
The most common source of water is a well. It most often reaches the second aquifer, and its depth is 10-30 m, depending on the depth of the groundwater. If the task is specifically to make water in a bathhouse of a wooden or other structure, then the potable degree of purification is not necessary, which means that it is enough to open the uppermost water carrier at a depth of 5-10 m. Such water should not be used for cooking, but for It's quite suitable for swimming.
Water supply diagram from a well
The depth of the well shaft is important for choosing the type of pumping equipment. The fact is that when lifting from depths of up to 12-15 m, you can safely use conventional centrifugal, surface pumps. With a deeper fence, you will have to lower the deep, submersible installation, which is somewhat more expensive and more difficult to operate.
Another option for a water source is a well. Its depth is 30-50 m, which makes it possible to reach the lower artesian layers, which provide especially pure water, and most importantly, a large and stable volume of liquid for a long time. It is the inextricability of the well source that is considered its main advantage, because wells tend to dry up periodically. The lifting of water from the well is ensured only by deep pumps.
In principle, a third option is also possible - pumping water from a natural reservoir. However, such a system is used quite rarely, and most often unofficially, because requires approval from the relevant authorities. The most important thing is that in this case you will have to solve the problem of installing a rather complex treatment plant.
Electric heater
Special electric heaters for bath needs are traditionally divided into two classes: storage-type boilers and units with flow-through action. When choosing a type suitable for given conditions, it is recommended to proceed from the following considerations.
In areas where there are frequent power outages, a storage tank is more suitable for installation in a bathhouse; in the simplest case, it is a container with a useful volume of 30 to 200 liters. A heating element and a special heat-sensitive sensor are installed in its internal space, which is responsible for maintaining the water temperature at a given level.
Among the advantages of such heaters it should be noted:
- increased level of electrical protection;
- the ability to use heated water for some time even in the absence of electricity;
- availability of several designs (vertical and horizontal);
- efficiency.
For areas with a reliable power supply, less common flow-through heaters that operate on approximately the same principle as a gas water heater may also be suitable.
The disadvantages of units of this type include significant energy consumption and the need for equipment in a bath with powerful electrical wiring. In addition, in order to maintain a fixed level of water heating in this case, it will be necessary to ensure the stability of its supply.
How to choose the right system?
When choosing a water heating system, consider the following parameters.
If you are choosing equipment for a small room, opt for a compact unit. Modern manufacturers offer mini-equipment that boasts high technical performance. Another important parameter is the speed of water heating. Some options quickly heat water to the desired temperature, others work more slowly, but have their own positive characteristics. If you don’t have a lot of time to warm up the steam room, choose the first equipment option. The most important characteristic when choosing equipment is consumables. In this case, you need to consider cost and capabilities. For some users, it is not profitable to use gas for the reason that it is not installed in a specific area. Many people are accustomed to heating with wood and continue to use the natural resource. Before making a choice in favor of a specific option, it is necessary to compare the advantages and disadvantages of all types of heating equipment
Pay attention to the cost of the unit. One model may have different prices depending on the store.
Chimney installation
Some users who are well versed in the intricacies of heat exchange processes manage to install a container for heating water directly in the chimney.
Note! To implement this solution, it is most convenient to use a ready-made opening in the wooden ceiling of the bathhouse, prepared when laying the chimney pipes.
In this case, simultaneously with the arrangement of the heating container, two related issues are resolved at once. First of all, the problem of fire-proof furnace cutting in the bathhouse is eliminated, and, secondly, the required water pressure is ensured in the shower room located under the tank.
Existing types of sauna stoves
Currently, there are a large number of varieties of furnaces with heat exchangers and water tanks.
Their diversity is due to the fact that there are factory-made ovens and home-made devices.
There are two types of factory devices:
- with built-in heat exchanger;
- with an external tank for heating water (usually installed on the chimney pipe).
In various designs of stoves with a heat exchanger, there are options for connecting a water system to provide hot water for the shower, or a heating system so that it constantly works in the bathhouse.
Reference. Homemade devices most often have a tank installed on the chimney pipe for heating water.
With pipe water tank
This design is the simplest version of the unit, since the water tank is installed directly on the chimney pipe, which requires virtually no additional labor costs.
Water is heated by the hot walls of the water tank body.
The general diagram of such a stove is as follows:
- blower;
- firebox;
- chimney;
- a water tank installed on the chimney.
The main feature of this design should be considered that there is no direct contact with the heat source in this stove - the water used as a coolant in devices of this kind is heated from the walls of the tank itself, located on the chimney.
Photo 1. A stove for a bath with a pipe-mounted water tank. The liquid is heated from the walls of the tank itself.
The dimensions of the structure can vary from 80 to 150 cm in height, and also from 30 to 60 cm in width, depending on the total volume of the steam room; with an installed water tank, the size of the structure can reach 200 cm in height (excluding the size of the chimney).
With a heat exchanger, how it works
A device with a heat exchanger is a more complex structure in which the coolant (water) circulates through the system due to the difference in temperature and the resulting difference in pressure.
The diagram looks like this:
- blower;
- firebox;
- chimney.
Important! In such a furnace, the heat exchanger is installed in the firebox body, but in a special way to avoid its direct contact with an open flame. The heat exchanger is connected to the water tank using two fittings, which allow for water circulation and uniform heating of the coolant
The heat exchanger is connected to the water tank using two fittings, which allow for water circulation and uniform heating of the coolant.
Since the heat exchanger is installed in the stove itself, its height, as a rule, does not exceed 120-150 cm, the width ranges from 30 to 60 cm. The height of the chimney is not included in the overall height of the structure.
The easiest way
Manufacturers make sauna stoves with ready-made water tanks. This option is the simplest for installation and further operation. Relevant for buildings that do not have gas and water supply communications; a limit on the use of electricity has been determined.
Hot water tanks can be installed in two ways:
- The tank is placed directly on the chimney pipe of the stove, the liquid is heated by the heat of the smoke coming out. At the same time, the pipe can heat up to very high temperatures (500⁰ C), quickly warming up the contents of the tank. The bottom of the container is equipped with an opening equal to the cross-section of the chimney pipe. It is necessary to ensure the tightness of the joints of the pipe and the tank at the inlet so that water does not leak out. The joint can be treated with a heat-resistant sealant, clay-lime-sand mortar. Cement mortar becomes cracked when exposed to heat. At the same time, such placement allows you to heat the water with heat, which is usually removed outside. And it is easier to install a chimney pipe inside the attic space, since excess heat is transferred to water.
- Mounted tank. It is placed wall-mounted on one side of the stove, most often inside the steam room (capacity 40-70 l). A wood stove heats the water in the tank in 1.2-1.6 hours. To speed up the process, you can thermally insulate the tank. It is also a simple, low-cost method that does not require significant material costs and is easy to maintain.
Placing such a tank inside the steam room is considered a disadvantage due to the large release of water vapor. For bathhouses located in the country, this is one of the few available ways to heat water that does not require any effort in winter arrangement. A current option for a classic Russian bath. It is not recommended to equip a sauna with such a tank.
Drain system
How to drain water in a bathhouse? This is a primary issue, without which it is impossible to equip your own water supply system. All water from bathhouses must be removed outside the building and collected in special containers. First of all, in the steam room and washing room, drain holes with a ladder are installed on the floor, and the floor itself has a slope for gravity flow of waste water to these holes. A liquid drainage system in the form of pipes or trays is installed under the floor.
The question of how to drain water in a bathhouse also involves solving the problem of its disposal. Wastewater must not be discharged into the ground without treatment. To ensure this, special filtering septic tanks are constructed in which mechanical, chemical and biological purification of the liquid occurs. As a rule, a septic tank system consists of 2-3 wells with filters, after which the water can be discharged into the ground. The drainage is provided by gravity, for which the pipes are laid with the required slope.
Scheme for draining water from a bathhouse These are sealed containers of the required volume in which water drained from the bathhouse is accumulated. When they are filled, the liquid is pumped out and removed.
When arranging a sewage system, it is important to remember that it must function in winter, therefore, it is necessary to use the same methods as when installing a water supply system - burial below the freezing level, thermal insulation of pipes, insulation of septic tanks
Water supply to a bathhouse in the absence of a centralized water supply is a rather complex, but completely solvable problem. When installing such a system, technical recommendations and sanitary requirements should be followed. When using electric heating or gas devices, we must not forget about fire safety.
Conclusion
In the video presented in this article you will find additional information on this topic. Also, based on the text presented above, we can conclude that a water heater that uses electricity for its operation can significantly increase the level of comfort in the bathhouse. At the same time, it will create a separate reserve if combined with standard systems using a furnace.
However, such a technological solution is not mandatory. A standard bathhouse can do without such devices, using traditional methods of heating water in the bathhouse.
We heat for heating
Frost creates additional requirements for how we heat a bathhouse in winter.
How to drown
The rooms become cold, approaching the temperature of the environment. In this case, heating immediately causes the appearance of condensation - water vapor from the air strives to instantly settle on something colder than the air itself.
The process of kindling in such conditions becomes an art. Of course, what type and fuel you use is also of great importance. It is difficult to cope with a brick stove; an iron stove is simpler in this regard.
There was a video on the Internet, the author of which shares his experience of lighting a Feringer stove at sub-zero temperatures:
But this is not so much about art, but about whether a small stove can bring a steam room out of the red in an hour. The author clearly shows that he can.
We want to say that you can’t break time records with a brick, but if it happens in winter, and the bathhouse has cooled down to sub-zero temperatures, then you need to be more careful with the stove.
After a cold period, the brick oven is first slowly heated and the moisture is allowed to evaporate.
The video below shows the process of heating a brick stove in a house, and this is somewhat different, because in the house the stove is not overcooled, it does not need to be gradually turned into positive mode, besides, it has a different operating mode - it is heated only in cold weather and constantly, and the bathhouse is heated for procedures at any time of the year. But so far no one has made a video about how you can heat a bathhouse in winter with a brick stove.
How can I heat it?
The question “how to heat a bathhouse in winter” can be answered in two ways - talk about what kind of firewood is best suited for winter heating. Or how to achieve a comfortable temperature for a person in rooms other than a steam room. Above, we have already talked about alternative methods for heating a bath without heating in winter.
Therefore, here we will only say that the only fuel whose quality depends on us is firewood. And you should know that this quality determines how well your stove will work. Specifically, how long will your chimney last without cleaning?
This is influenced by the presence of resin in the firewood - firewood made from coniferous wood is, of course, the cheapest, but it also creates the most problems. Because during combustion, more soot is formed, which settles in the chimney pipe.
Hardwood is much better in the firebox. But they also differ in the heat of combustion. Unfortunately, valuable hardwood species have the highest combustion heat - oak, hornbeam, and ash are good for burning. But, on the other hand, not all of their wood is suitable for processing and turning into building materials, furniture or something else.
Fruit trees (cherry, apple, etc.) are suitable for heating; they are only slightly inferior in heat of combustion to the species mentioned above.
Next come deciduous trees, but not so rare - birch, alder, etc. It is better to use them than conifers.
Another important characteristic of firewood is its moisture content. The damper the wood, the worse it burns, everyone knows this. Therefore, the woodpile should be located in a dry place, protected from precipitation, and you can also dry the wood next to the stove, using its heat to drive out excess moisture from the wood, which will then go into the firebox.
Drying the bath
There are two components to quickly drying wet rooms: heating and ventilation. They should not be considered separately, because together they work most effectively. You just need to combine them in a specific case.
How to dry: ventilation methods
The ventilation system is laid at the stage of construction of the bathhouse (see here about the diagrams and design of the bathhouse ventilation). Therefore, if something is forgotten, it may be too late to redo everything.
For example, vents are usually made in the foundation - these are through holes lined with sewer (most often) pipes that lead to the underground space. They have plugs on the outside that allow you to open and close them at the right time.
For more details about the scheme, see
Such vents are opened only after procedures. And they serve for better ventilation and drying of the bath.
Also, another through hole is usually made in the wall of the steam room under the shelves, leading to the street. On the inside it has an adjustable plug. This hole is also used to speed up the drying of the steam room.
You can dry the bathhouse in winter with the help of ventilation by opening the windows and doors wide - after all, the air inside is much more saturated with water vapor. But you shouldn’t think that all the moisture will leave the bathhouse only thanks to open doors and windows.
In addition to ways to create a draft simply by opening holes, there is also a method where ventilation actively cooperates with heating and works when the stove is on - this is bastu, which you can read about.
Well, don’t forget that even if natural ventilation is not installed correctly or its power is not enough to ventilate the bathhouse, you can always install fans in the air ducts. Forced ventilation, although noisy, is still effective.
BY THE WAY! Heat guns can help here too.
For those who believe that heating alone is enough, and ventilation becomes optional, we recommend watching the video by Konstantin Bely:
After washing: methods of heating
Heating is just as necessary for drying as ventilation. You understand the mechanism: by heating water molecules, you make them more mobile, transform the water into a gaseous state (steam), and it is easily carried away by the breeze. What will the breeze do if the water is cold? Nothing. And if there is no breeze, the steam will cool over time and calmly settle as condensation.
So, the easiest way to dry a bathhouse after washing in winter is to put one or two logs in the firebox and let them burn out. All ventilation openings must be open.
This is for an iron stove. A brick stove is a heat-storage stove, so its heat is enough to dry the bathhouse after the procedures (together with open ventilation).
***
Well, as you can see, you have to invest some money and make an effort in order to use a large bathhouse in the winter. The smaller it is, the easier it is to warm it up even in cold weather. The power of the sauna stove is calculated for the steam room; it is difficult to fit other things into its responsibilities, because there is summer when all this is not needed. So it is better to use autonomous heaters.
Self-production
Some users prefer to make wood-burning boilers with their own hands, which is only possible if you have the necessary tools and practical skills.
When assembling a heating unit yourself, be sure to consider the most labor-intensive design option, which you have to deal with in the absence of a plumbing system.
In this situation, you will need a device capable of accumulating (accumulating) liquid under a certain pressure. The function of such an accumulator can be performed by a container placed on an elevated place, from which a pipe with a pre-calculated diameter is drawn.
The heating unit itself must be installed on a well-leveled and sufficiently rigid platform to ensure a stable position. For its installation, a pre-concrete patch within the bathhouse that has a suitable size is best suited.
