ELECTRIC CIRCULATION SYSTEM OF WATER HEATING Russian patent published in 2011 - IPC F24D13/02 

FIELD: power engineering.

SUBSTANCE: electric circulation system of water heating represents a circulation system of water heating with electric heating, comprises one block from a radiator. Besides, the specified radiator is a radiator with hot water circulation, having an inlet for hot water supply and an outlet for hot water discharge; one block of a multi-block heating device, shaped as a square cylinder arranged as capable to ensure operation of one unit from a radiator; in which an air compartment tank operating under pressure, a circulation pump and tubular heaters are connected to each other by means of a system of pipelines, a T-shaped joint, having a check valve, and a T-shaped joint comprising check valves, are arranged in series inside the track of the pipeline system, a bypass pipe diverges from the T-shaped joint, and an auxiliary tank is located at the end part of the bypass pipe, which diverges from the pipeline system, thus ensuring a function of hot water circulation in a multi-block heating device, besides, the multi-block heating device is connected to a radiator by means of a discharge side pipe and a return side pipe.

EFFECT: provision of simple maintenance, higher efficiency of system operation.
