FIELD: heating systems.
SUBSTANCE: method of reducing heat and electric energy consumption in circulation hot water supply system consists in the fact that water flow for hot water supply is measured, rotating speed of circulation pump is controlled in inverse dependence on ratio of measured water flow for hot water supply to original flow value, and controlled rotating speed is restricted with minimum value.
EFFECT: increasing economic efficiency of hot water supply systems made both as per open and closed scheme without decreasing water supply comfort.
