The study of exploitation of vertical ground heat exchangers with heat pump was conducted. Recovered heat was used in central heating and hot water installations. The daily heat production yield from two vertical ground heat exchangers with depth 70m amounted 0.23GJ and coefficient of performance was COP = 2,46-3,05. Continuous exploitation of ground without thermal regeneration did not cause any significant reduction of the heat obtained from the ground in next heating seasons in studied installation. There is no need to regenerate of the ground in summer which is associated with an additional energy inputs(original abstract)
