FIELD: construction.
SUBSTANCE: coolant 8 is heated in a heat pump system of heat and cold supply 5, afterwards it is supplied into a pipeline 7, flowing through which it heats a site 6. After travelling through the entire pipeline the coolant is again supplied into the heat pump system of heat and cold supply for repeated heating. Thawed water produced on the surface of the site 6 is removed along a satellite pipeline 3 to moisten a soil massif 1. In summer time to prevent system outage it is possible to cool coolant in the heat pump system of heat and cold supply, so that when flowing along the pipeline it cools the site 6 below the dew point, and condensate is formed on it, to clean the site surface from dust and garbage.
EFFECT: higher device operational reliability.
