FIELD: aerodrome, motor road and bridge building and usage, particularly to protect coatings of above structures against ice formation during cold periods and against softening under the action of high temperatures during warm seasons. ^ SUBSTANCE: device includes tubular register arranged in covering, recuperative heat exchanger, water intake well provided with immersed pump and water conduits, "cold" pumping well arranged downstream underground water relative water intake well. Device also has "warm" pumping well arranged in line with above "cold" pumping well and water intake well. "Warm" pumping well is located upstream underground water relative water intake well and spaced a distance equal to path which underground water passes during half a year. "Cold" pumping well is spaced a distance equal to sum of range radiuses of wells, from water intake well. ^ EFFECT: increased efficiency of underground water-bearing horizon heat usage, increased efficiency of solar energy utilization, possibility of continuous usage of above engineering structures during the whole year. ^ 1 dwg
