Indirect THERM heating heaters prepare hot domestic water in connection to another source of heating water, usually with a gas boiler, gas condensation boiler or an electric boiler. In the case of increased consumption of heating water, storage tanks regularly heat water and operate similarly as flow heaters (depending on the power of the heat source). For heating the storage tank can by used all boilers THERM, but boilers that are designated "Only for heating", it is necessary to expand the set boiler - storage tank by adding an external three-way valve.
The advantage of the connection of the heating water with the THERM boiler is based on easy installation and connection to the source of the heating water. The boiler also quickly heats up the hot domestic water. The high quality of polyurethane insulation ensures minimum heating losses and a fluent adjustable temperature of heating water up to 60 °C. The built-in Mg anode (magnesium anode) is a matter of course, which increases resistance to corrosion.
