FIELD: power engineering.
SUBSTANCE: invention relates to heat power engineering and renewable power engineering and can be used for heat supply of autonomous objects – houses, sanatoriums, farms and other autonomous objects. Water-heating installation with efficient use of solar energy includes a solar collector connected to a hot water supply boiler through a three-way valve of average solar activity and a three-way valve of high solar activity, heat pump, circulating pump, primary circuit circulation pump, three-way valve, heat accumulator at phase transition, connected to solar collector through three-way valve of low solar activity and a heating buffer tank, connected via a secondary circulation pump to a heat pump, and a three-way valve of the heat pump.
EFFECT: higher efficiency of the plant.
