FIELD: heating.
SUBSTANCE: invention relates to boilers with built-in water heater and can be used to provide heating and hot water without additional installation systems for additional equipment in private houses and organizations. Boiler with a built-in water heater is made in a single housing, inside which there are: a double-circuit gas boiler and a water heater, a safety group, connecting pipes and shut-off and control valves. Water heater is made in the form of a layer-by-layer heating water heater, having a pipe for supplying cold water to the lower part of the water heater, a pipe for water intake from the lower part of the water heater, connected through a pump of the HWS circuit to the secondary heat exchanger of the boiler, having a pipe connecting the hot water outlet from the secondary heat exchanger to the upper part of the water heater. At the same time this branch pipe is equipped with hot water outlet to the consumer. And the water heater contains a drain branch pipe, a safety valve of HWS, a temperature sensor, an anode protection against corrosion, an expansion tank of the HWS circuit.
EFFECT: wider range of heating and hot water supply means – creation of a gas double-circuit boiler with a built-in layer-by-layer heating water heater, which enables to obtain hot water immediately after switching on the boiler.
