FIELD: power industry.
SUBSTANCE: hot water supply system includes the following: flow transmitter, heat exchanger, water tank, temperature sensor, controller equipped with inlet device, and pump installed on the pipe connecting the first branching point provided on the pipe on the outlet side to the second branching point provided on the pipe on the inlet side. The proposed method provides for the following stages: flow rate of the water supplied to hot water supply system is measured by means of flow transmitter; pre-heated water is brought by means of a pump into circulation movement in hot water supply system along internal circuit connecting the first branching point, the second branching point and heat exchanger. The above stage is implemented after the controller switches off the heating device, when the measured flow rate becomes equal to or less than operational flow rate of water supply system; circulating water temperature is measured by means of temperature sensor and the pre-set temperature exceeding the temperature specified by the consumer is specified.
EFFECT: possibility of controlling hot water temperature even at low water pressure at the system outlet, or at low operational flow rate.
