FIELD: heating.
SUBSTANCE: holes through which the heat carrier flows are located at least on two concentric circles; at that, control mechanism is made so that it can control the valve system provided with possibility of directing the heat carrier to the holes which are located on one and the same circle, and thus heating or cooling the ground at the above circle; at that, when heat carrier temperature is higher than the ground temperature, internal circles are heated quicker than external circles are, and when heat carrier temperature is lower than the ground temperature, external circles are cooled quicker than internal circles are. Invention also refers to the device in which the proposed method is implemented.
EFFECT: method and device allow more effective using of the ground temperature.
