Most industrial manufacturers of sauna stoves with heat exchangers use this method of heating water. The tank is easy to install, the only drawback is its bulky appearance and the need to constantly add water.

Power calculation
The correct choice of heat exchanger should take into moj data the indicators of the main heating device. Here the volume and power of the sauna stove are taken into account.

To select the optimal equipment and components, you need to consider the following rules:

the sauna stove gives part of the energy to the heat exchanger. It is not rational to use large tanks so that a larger volume of water can be heated. Such an approach can significantly reduce the comfort of staying in the steam room, increase fuel consumption and create an unfavorable microclimate. The water tank should not take more than 10% of all the energy generated;

heating radiators and heat exchanger are connected to each other by pipes. maintain proper circulation, the length of the pipes should not exceed 3 meters. Here, the diameter of the pipelines and the rational slope that ensures gravity flow are taken into account. Using a pump makes it possible to increase the length of the pipeline and not adhere to slopes;
It is important to create a balance between fast and slow heating of the liquid in the system. Do not allow the water to boil constantly. If a small tank is used for the heat exchanger, boiling will occur in 2 hours and will lead to the formation of a large amount of low-quality steam. When installing a volumetric heat exchanger, heating will not occur on time, and the process will drag on for several hours. It is necessary to create conditions so that the water is hot 2 hours after lighting the sauna stove.

Now let's talk about the optimal dimensions of the heat exchanger. It should have a power reserve, which will allow maintaining the thermal mode after the heating device goes out. Of course, the water begins to cool down quickly, so it is important to create the right unit that allows maintaining the temperature as long as possible.
