HEAT SUPPLY SYSTEM Russian patent published in 2018 - IPC F24D1/00 

FIELD: heating system.

SUBSTANCE: heat supply system includes the hot water boiler with the main flue with the sliding gate and attached to it the bypass flue with sliding gate on the inlet and outlet, which has consistently attached to return heat system pipeline, condensing the heat exchanger with the input and output pipes and the water economizer fitted with interconnected irrigating ditch and tray. At that the heat pump is installed on the return pipeline, connected to the heat system boiler, the evaporator and condenser of which are connected to the inlet and outlet pipes of the condensing heat exchanger, respectively. And the low-temperature heat system circuits with floor heat panels are additionally connected to the return pipeline of the heat system according to the dependent scheme.

EFFECT: return heat system water temperature reduction, entering the condensing heat exchanger, which provides useful utilisation of the large amount of heat due to the water vapor condensation.
