FIELD: heat power engineering.
SUBSTANCE: invention relates to the field of heat power engineering of autonomous heat supply systems for producing hot water for heating and hot water supply. A wall-mounted boiler is proposed that operates with two sources of thermal energy: the energy of combustion of gaseous fuel at high power and the electric energy of thermal electric heating elements at low power. In the return line of the gas boiler, after the circulation pump, to the main heat exchanger of the gas boiler, a flow-through block of thermal electric heating is installed. To reduce heat losses through the chimney, an air valve is installed in the design of the hybrid wall-mounted boiler.
EFFECT: implementation of the invention makes it possible to create a hybrid wall-mounted gas-electric boiler operating in heating mode with a modulation equal to 50, which makes it possible to achieve the highest energy efficiency of wall-mounted boilers.
