You can make a stove yourself, or buy a ready-made factory-made model, install it strictly according to the instructions. Gas boilers are popular. If you decide not to buy a ready-made Samovar-type stove for baths, the owner builds it with his own hands, using one of the schemes most suitable for the bath room. There are many schemes of independent construction of the heater, it is important to choose the best option, with maximum heating of water.
Build your own sauna heater is good in the classic style, with a suitable layout. It is made of refractory bricks, ceramic plates with the addition of metal. The stove should be installed against the wall. Samovar-type tankIt is recommended to place the tank on top of the stove for filling and heating water.
The front side of the stove is equipped with a space for filling with stones. A stove with this layout will heat the water in the tank efficiently, quickly. There are schemes with the location of the tanks on the pipes that lead away from the stove, but this is a less efficient option for heating water. After all, the most important thing is to sauna stove. gave the heat to the water as much as possible. Metal tanks with thin walls are best for tanks.
A combination arrangement when the tank is installed half above the sauna heater and half to the chimney may be optimal. In this solution it is recommended to weld a chimney elbow into the metal tank and to direct the chimney from the fuel compartment horizontally. At the front of the fuel compartment is necessary to leave space in it for the stones.

Common types of tanks
There are a number of different types of Samovar-type tanks for bathtubs. All of them are practical, efficient, and differ in the area of contact with heating surfaces. They all have the same task – not to bring water to boiling point, so that in the steam room no coarse-dispersed steam, heavy for breathing, is formed.
Types of tanks:
The most common type of tank used by homeowners is the tubular type. They are practical, the area of their contact with the heating chimney is very large. Place such tanks For the sauna stove In the steam room, in the attic of the banya.
There’s an important point to consider here:
- method of filling the tank with fresh water;
- No direct contact with the furnace.
The tank has no contact with the sauna heater and allows it to heat up to its full potential. The tube tank is able to maintain the heat of the water for a long time, received after it is fully heated. The required water temperature is maintained by a weak burning of the sauna heater.
Tanks of remote type are convenient because they can be placed anywhere in the steam room. The heat of the furnace such tanks receive through the heat exchanger installed on the chimney, the design of these schemes are most reminiscent of the samovar-type tanks for bath stoves. From the heat exchanger to the tank there are two pipes, providing natural circulation of water according to the law of physics – the heated water will rise up, it will be replaced by cold water coming from the lower pipe. This method of heating water is considered the slowest, the water almost never comes to a boil.
External tanks with a heat exchanger device are highly valued by fans of dry steam. They are convenient when the room of the bath is divided into two compartments – the steam room and the washing room. In this case the tank is installed in the washing room. Water circulation is accelerated by additional installation of a water pump when using this scheme. Practice shows that water using this scheme warms up for a long time: in the summer – for 1.5 hours, in winter cold – for 2-2.5 hours. But at the same time the steam room is filled with dry heat. There is a disadvantage of the scheme of the bath with a remote tank – in winter, if the rest of the water is not drained, it will freeze in the heat exchanger pipes, especially when using flexible corrugated pipes.
Most often in the Russian bath use built-in tanks. Practice shows that they give the highest efficiency figures. Heating of water is faster than in furnaces built according to other schemes, as a large area of the tank is in direct contact with the fire in the fuel compartment of the furnace.
That said, there are some nuances to consider in furnishing a furnace with a built-in tank:
- The volume of the tanks used is limited by the design of the furnace;
- rapid heating of water leads to its boiling, formation of coarse vapor, increasing humidity;
- to prevent an early boil, the water heating is monitored by the host, constantly draining the hot water, changing it with cold water;
- The water tank can take heat from the stove, preventing it from heating up; completely filling the tank and heating it above 100 degrees requires the stove to give up all the heat energy, preventing normal heating of the stones.

Choosing a boiler option for the steam room
Installation of an electric boiler with cold water supply is not justified, because the bath is still heated and the heat from the heater will heat the water to the desired temperature, if the correct model of the tank for the sauna stove.
Bath tanks are chosen:
- By the material of its manufacture;
- on the optimum volume for the bath room.
The material of the tank determines the speed of heating water, how long it retains its temperature, and the durability of the tank. Today tank installation for the steam room requires a careful, conscious choice of material by the owner.
Tanks are made of:
- cast ironThe only disadvantage is its heavy weight, which makes it difficult to install and use;
- cast iron enameledVery reliable containers, but hard to find on sale;
- metal; available in different versions;
- enamels; these tanks are installed as remote, or tubing, material not intended to be directly installed over the furnace fire;
- Of a particularly durable hardened stainless steel; today boiler of this material is used more often than others, allows installation on pipes; the material has excellent thermal conductivity, practically does not deform from temperature fluctuations; it is easy to care for, to clean it from scaling.
For hot water, the best tank material is metal. Sometimes there are variants made of wood, plastic. But their use is limited: they cannot come into contact with parts of the furnace structure heated above 90 degrees.
Metal tanks are made in several variants:
- Extra-strong steel with galvanizing, painting with heat-resistant dyes – not widely used;
- Extra-strong steel with enameling – by far the most common containers for home baths, boilers, and kitchen heaters;
- thick-walled galvanized steel without painting, similar in appearance to the material of common galvanized cookware, buckets;
- Stainless steel is the best type of boiler that has received the most use.
When cost is an issue, enameled steel tanks are the most affordable. They were developed specifically for high water heating. At a low price customers find suitable for their plans options tanks of different configuration and volume.
Choosing a tank by its volume requires matching the liters of the area to be heated. To wash one person, 10 liters is enough. The calculation is simple: by multiplying the number of people 10. The result is the volume of the tank to buy.
Factors to consider in selecting a tank are:
- Low power of the sauna heater with a large area of the steam room will not give normal heating of water in capacious boilers;
- A small volume tank will result in a constant boil off of the water.
Choosing the liter size of the boiler on the sauna stove, the owner is required to calculate all factors to opt for the best option. There are many conditions to consider when selecting the best capacity for heating water. The choice will be most correct if the owner is consulted by experts.
Pros and cons of samovar-type systems
Tanks installed on the chimney outlet from the furnace are called samovar tanks. They are an integral part of the knee on the chimney pipes. Such installation is convenient, gives quick and even heating of water. In addition, and the design is compact, easily placed in any bathing room.
- inconvenient filling of the tank with water; this issue is solved by placing the upper part of the boiler in the attic with a water supply line;
- possible miscalculations in the use of tanks of unsuitable volume, from which the water quickly reaches boiling point.
- The right choice of tank material – stainless steel; it is not afraid of corrosion, serves its purpose flawlessly for a long time;
- The high coefficient of thermal conductivity of stainless metal gives rapid heating of water in the samovar tank;
- The strength of stainless materials prevents the tank from deforming during temperature fluctuations;
- safety of the purchased ready-made samovar tank.
A wood-fired bathhouse is a place of high fire danger. When using home baths, you must follow precautions to avoid burns from hot water, fire. By strictly following all the conditions stipulated in the Instructions for Use of Fuel Tanks, the possibility of unforeseen injuries and dangerous situations is prevented. It is important to remember about the timely filling of the tank with water, not to flood the stove with an empty boiler, so that the high temperature of the fire will not deform it, not to damage the welds. In winter, when the bath is not heated, it is necessary to drain the water from the system, so that it does not freeze to ice – this can cause rupture of metal.
And a little bit about scaling in boilers.
If the cottage or cottage with a bath is in a region with hard tap water, in the boilers is formed scale. It is deposited in the place of extreme temperature heating, reduces the rate of water heating, significantly reduces the conduction of heat in the pipes. Scale from hard water builds up constantly, not an even layer, has a high coefficient of resistance to heat.
From the appearance of scale inside the pipes decreases the strength of the samovar sections of the chimney, the service life of the entire structure falls, deteriorates Samovar-type heat exchanger. If the pipes and boilers are not decalcified in time, water will flood the fuel compartment of the stove.
Recipes for folk remedies against limescale
- Baking soda. Bring water to a boil in a tank, pour a packet of baking soda into it. Then let the water cool down, bring it to the boil again. Water with soda is drained, fill the tank with clean water, pour half a glass of vinegar essence into it. Bring to a boil, leave to cool. Once again bring to a boil, half an hour later pour it out. From the effects of soda and acid scale is loosened, it is removed with a hard sponge, ruffle.
- Citric acid. Without sparing the bags of citric acid, it is poured into a tank of cold water, then brought to a boil. Let stand for a while, drain the citric acid water, fill the tank with clean water, and bring it to the boil. Acid dissolves all the scale, the tank is rinsed with clean water. The method is cheap, fast, but has a significant drawback: the acid, affecting the scale, affects the material of the metal, its surface will be rough, and fresh scale will quickly appear again. It will be more and more difficult to clean boilers with citric acid each time.
- Vinegar. Pour a glass of vinegar into a filled tank, boil for 20 minutes. Acid is effective, its disadvantage is the residual smell. Clean the boiler with the windows open, then thoroughly rinse the system, ventilate the room for a long time.
Today, all methods of heating water in home baths are widely used. Designs of different systems are well thought out, convenient to use and safe. It is important to qualitatively perform all conditions of installation.
