FIELD: heating.
SUBSTANCE: extra heating of soil is carried out by applying the solar radiation, as an outside heat source, inside the array of soil, by absorption of concentrated solar radiation in the receiver of solar radiation and heat transfer to the amount of gravel-water heat exchanger-accumulator which is in heat contact with soil. Throughout the year, selection of low-grade heat and its transformation using a heat pump cycle to a higher level, that meets the requirements of heating and hot water supply system, is carried out by transmission of heat through a heat exchanger connected to the contour of heat pump evaporator.
EFFECT: invention can improve energetic efficiency of processes of heat exchange, expand the scope and reduce the complexity of method.
