APPARATUS FOR HOT WATER SUPPLY AND A METHOD OF RECYCLING WASTE HEAT IN A HOT WATER SUPPLY PLANT Russian patent published in 2021 - IPC F24D3/08 F24D19/10 F24H9/20 

FIELD: heat exchange.

SUBSTANCE: group of inventions relates to a hot water supply installation and to a waste heat recovery method. According to the present invention, the hot water supply plant comprises an explicit heat exchanger for heating the heating fluid by means of the combustion heat from the burner, heat exchanger for hot water supply for hot water generation by means of heat exchange between heating fluid heated by heat exchanger of explicit heat, and ramjet water and hot water supply to the tap. Proposed plant comprises pump for circulation of heating fluid through heating fluid flow path that connects heat exchanger of explicit heat and heat exchanger for hot water supply. Installation for hot water supply comprises a signal receiving unit for receiving a signal for ending use of hot water and a control unit for stopping operation of the burner based on the signal received by the signal receiving unit, and pump control for heating fluid circulation.

EFFECT: present invention is aimed at creation of a plant for hot water supply, which provides hot water supply by utilization of waste heat of pipeline and boiler as heat source, when amount of required remaining hot water when using hot water of flow boiler is small.
