The paper deals with assessment of thermal fields and temperature changes in ground massif with horizontal heat exchanger used as a heat source for a heat pump. Temperatures in the zone of the horizontal ground exchanger are compared with temperatures in a reference land. Changes of heat potential of the soil during the heating period are also assessed. Possibilities of recovery of thermal potential of the ground massif when utilizing vertical and horizontal exchangers are analyzed in the opening part of the paper. The results of the first verification indicated that average temperatures in the horizontal planes of the ground massif did not differ considerably with distance from the exchanger tube. Differences in average temperatures in reference and experimental lands confirmed sufficient heat potential of the ground massif even at the peak of the heating period. The differences in average temperatures reached up to 6.51 K in the end of the heating period while at the beginning of the heating period, the differences in average temperatures dropped to 1.35 K. The differences between maximum and minimum temperatures in the zone of the ground exchanger reached up to 1.9 K at the peak of the heating period and rose to 3.9 K at the beginning and end of the heating period. The first results of our measurements indicate the necessity of accumulation of thermal energy in the soil massif in the summer period like in case of the vertical exchangers.
