It is important to provide a certain height difference between the outlet of the sauna stove heat exchanger and the bottom of the water tank. Usually, this value is selected within 50-70 cm. For box and register schemes, flat coils, the tank is at a level of 120 cm above the floor. This is convenient, you can scoop up hot water through the top hatch.

It is another matter if the coil of the heat exchanger for the bath is installed on the chimney pipe. In this case, the tank will have to be raised to a height of 180-200 cm, therefore, a bronze tap for hot water should be installed in the bottom or at the outlet of the circuit.

The pipes leading from the heat exchange circuit of the furnace to the tank are usually placed at an angle. The cold main from the lower branch pipe is supplied to the feed tank at a right angle, this ensures the maximum hydrostatic pressure in the circuit. The outgoing main is installed at an angle of 25-30°. This is done to separate air bubbles and steam formed in the water flow during heating.

On the cold main line, it is necessary to make a knee and moj data a drain ball valve, with the help of which you can easily drain the water from the bath heat exchanger.

A heat exchanger for a sauna stove has long been an integral attribute of a real steam room. It can be easily made with your own hands, ordered from a craftsman or bought ready-made, even with installation. Small expenses on additional equipment of a sauna stove will pay off a hundredfold with a higher level of living conditions, because it is not necessary to heat the steam room to provide the whole family with hot water in the summer.


DIY Heat Exchanger for a Sauna Stove
It is always pleasant to visit a well-designed sauna, which has a high-quality heater capable of producing light steam. The water supply and heating system also play a big role in the steam room, so you should always take the time to design the heat exchanger.

Warm water for the steam room can be heated in two ways: using an electric boiler or using a heat exchanger, which is located in the bath and takes thermal energy from the combustion of fuel.

The first version of a heat exchanger for a sauna stove is not always rational to install, since it requires a large amount of electrical energy.
