FIELD: heating.
SUBSTANCE: invention relates to heat engineering and can be used for heat supply and hot water supply in decentralized low-power objects using geo-and solar power energy. Heat supply unit includes circulation circuit consisting of well-heat exchanger for selection of low-potential heat of rocks, heat pump and solar collector feed pipeline connected to supply and discharge pipelines for heat carrier circulation, the installation has solar radiation concentrator consisting of the hemispherical surfaces arranged one above another on posts, upper hemispherical surface of the convex side directed to the concave side of bottom hemispherical surface, on which there is a solar collector, the convex and concave sides of the hemispherical surfaces are made from tempered glass with mirror sputtering.
EFFECT: invention shall provide higher thermodynamic efficiency and uninterrupted supply of heat energy to consumer based on renewable energy sources.
