METHOD OF PROTECTION HEATING PIPE FROM THE FROST AND PIPE OF HOT WATER SUPPLY Russian patent published in 2017 - IPC F24D19/10 F24H9/20 

FIELD: heating.

SUBSTANCE: method includes the steps of: if the heating temperature is lower than a predetermined temperature protection from freezing by the controller translate the three-way valve in the hot water supply mode and perform combustion operation in the heater and the circulation of heating water in a closed circuit consisting of the heating a heat exchanger, a three-way valve and the hot water heat exchanger by the pump. In the heat exchanger of hot water supply heat from the heating water transfer pipe hot water; and if the heating water temperature reaches a predetermined temperature by the controller to translate the three-way valve and the heating mode operation is carried out quench heater and circulating heating water for heating the pipe by driving a pump.

EFFECT: to prevent freezing of the heating pipe by applying a heating water temperature sensor positioned in the water heater, to prevent freezing pipes hot water by controlling the three-way valve.
