I wanted to have my own bathhouse at my summer cottage. I have already built the base, and now I am working on a stove with a water tank. I decided to use a samovar-type tank because of some of its advantages, but before that I studied two other design options. Next I will talk about sauna stoves with tanks for water in the bathhouse and, in particular, a little about installing a samovar-type water tank.

Common types of tanks
Various samovar-type tanks for bathhouses are widely used today. All of them are practical, effective, and differ in the area of contact with heating surfaces. For all of them, the same task is not to bring the water to a boil, so that coarse steam that is difficult to breathe does not form in the steam room.
Types of tanks:
- pipe;
- remote;
- external;
- built-in
Most often, owners use pipe-type tanks. They are practical, the area of their contact with the heating chimney is very large. Such tanks for sauna stoves are located in the steam room, in the attic of the sauna.
There is an important point to consider here:
- ease of use;
- method of filling the tank with fresh water;
- no direct contact with the oven.
The container does not have contact with the heater and allows it to warm up at full strength. The pipe tank is capable of maintaining the heat of the water for a long time, obtained after it has completely warmed up. The required water temperature is maintained by low combustion of the heater.
Remote-type tanks are convenient because they can be placed anywhere in the steam room. Such tanks receive heat from the stove through a heat exchanger installed on the chimney; in design, these schemes most closely resemble samovar-type tanks for sauna stoves. Two pipes are stretched from the heat exchanger to the tank, ensuring natural circulation of water according to the law of physics - warmed water will rise upward, and 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 dry steam lovers. They are convenient when the bathhouse is divided into two compartments - a steam room and a washing room. In this case, the container is installed in the washing room. Water circulation is accelerated when using this scheme by additionally installing a water pump. Practice shows that using this scheme, water takes a long time to warm up: in the summer - in 1.5 hours, in cold winters - in 2-2.5 hours. But at the same time, the steam room is filled with dry heat. There is a minus to the bathhouse design with a remote tank - in winter, if the remaining water is not drained, it will freeze in the heat exchanger pipes, especially when using flexible corrugated pipes.
Most often, built-in tanks are used in Russian baths. Practice shows that they provide the highest efficiency indicators. Heating of water occurs faster than in furnaces built according to other schemes, since a large area of the tank is in direct contact with the fire in the fuel compartment of the furnace.
At the same time, when installing a stove with a built-in tank, some nuances must be taken into account:
- the volume of tanks used is limited by the design of the furnace;
- rapid heating of water leads to its boiling, the formation of coarse steam, which increases humidity;
- to prevent early boiling, the owner monitors the heating of the water, constantly draining the hot water and replacing it with cold water;
- the water tank can take heat away from the stove, preventing it from heating up; Completely filling the tank and heating it above 100 degrees requires the furnace to release all the thermal energy and interferes with the normal heating of the stones.
A stove with a samovar-type tank is shown in the photo.

The simplest option is to find, select and buy what you need without resorting to physical labor. The choice in specialized companies is now quite wide, so you just need to decide on it.
Pros and cons of samovar-type systems
Tanks installed on pipes leading from the furnace are called samovars. They are an integral part of the elbow on the chimney pipes. This installation is convenient and provides quick and uniform heating of water. In addition, the design is compact and can easily be placed in any bathhouse.
Negative points
- inconvenient filling of the container with water; this issue is solved by placing the upper part of the boiler in the attic with a water supply;
- possible miscalculations in using tanks of inappropriate volume, as a result of which the water quickly reaches the boiling point.
Positive points
- correct choice of container material – stainless steel; it is not afraid of corrosion and serves its intended purpose flawlessly for a long time;
- the high coefficient of thermal conductivity of stainless metal ensures rapid heating of water in the samovar tank;
- the strength of stainless materials does not allow the container to deform due to temperature changes;
- safety of the purchased ready-made samovar tank.
A wood-burning bathhouse is a place of high fire danger. When using home baths, you must follow precautions to avoid burns from hot water or fire. If all conditions stipulated in the Fuel Tank Operating Instructions are strictly followed, the likelihood of unforeseen injuries and dangerous situations is prevented. It is important to remember to fill the container with water in a timely manner, do not flood the stove with an empty boiler, so that the high temperature of the fire does not deform it or damage the welds. In winter, when the bathhouse is not heated, it is necessary to drain the water from the system so that it does not freeze to ice - this can lead to rupture of the metal.
Samovars for baths
remote water tank
The main material for the manufacture of such a stove is a “potbelly stove”. It already has a water container inside. We place a chute for stones on top. We make the stove and register from sheet steel four to five millimeters thick. We make the tank separately and install it above the register itself. The register and tank are connected using tubes (a hose may also work).
And a little about scale in boilers
If a summer house or cottage with a bathhouse is located in a region with hard tap water, scale will form in the boilers. It is deposited in the place of extreme temperature heating, reduces the rate of heating of water, and significantly reduces the conductivity of heat in the pipes. Scale from hard water constantly builds up in an uneven layer and has a high coefficient of heat resistance.
The appearance of scale inside the pipes reduces the strength of the samovar sections of the chimney, reduces the service life of the entire structure, and deteriorates the samovar-type heat exchanger. If pipes and boilers are not cleaned of scale in a timely manner, water floods the fuel compartment of the stove.

Recipes for folk remedies against scale
- Baking soda . In the tank, bring the water to a boil, pour a pack of soda into it. Then let the water cool and bring it to a boil again. Drain the water and soda, fill the tank with clean water, pour half a glass of vinegar essence into it. Bring to a boil, leave to cool. Bring to a boil again and pour out after half an hour. The influence of soda and acid loosens the scale; it is removed with a hard sponge or brush.
- Lemon acid. Not sparing the bags of lemon, pour it into a tank of cold water, then bring to a boil. Let it sit for a while, drain the water with citric acid, fill the tank with clean water, and bring to a boil. The acid breaks down all the scale deposits, the tank is rinsed with clean water. The method is cheap, fast-acting, but has a significant drawback: the acid, acting on scale, affects the metal material, its surface will be rough, and fresh scale will quickly appear again. It will become more and more difficult to clean the boilers with lemon each time.
- Vinegar . Pour a glass of vinegar into the filled tank and boil for 20 minutes. The acid acts effectively, its disadvantage is the residual odor. You need to clean the boiler with the windows open, then rinse the system thoroughly and ventilate the room for a long time.
Today, all methods of heating water in home baths are widely used. The designs of the various systems are well thought out, easy to use and safe. It is important to fulfill all installation conditions efficiently.
The simplest homemade stove options
For those who have never encountered the stove business, you can try for the first couple of years to study the design of a bathhouse stove of the simplest design and build one that will heat the bathhouse, heat the water and produce pleasant steam.
Also, you can make a stove from ordinary or rubble stone, or carefully baked brick. The thickness of the walls should be from 13 to 25 cm, and the stones should weigh 1-5 kg. As stones for the stove, you can take granite, rubble or pebble, but not flint, which shatters into pieces when heated. And in order for a self-made sauna heater to accumulate heat, you can add cast iron to it so that they account for 20% of 80% of the stones.
Usually those who at least once in their life have tried to make a stove for their favorite bathhouse with their own hands are terribly proud of their success and proudly show their achievement to everyone they know.
