In the period between December 2011 and March 2013, there were conducted the research on the acquisition and
processing of the heat from the ground with usage of the vertical heat exchangers and heat pump with capacity of 8 kW. The
daily heat production yield amounted to 0.486 GJ and lack of thermal regeneration in spring-summer period of the
exploited deposit in winter time for two years (2012 and 2013) did not cause any significant reduction of the heat obtained
from the ground. And the difference in the amount of heat generated by the heat pump did not affect the temperature of the
heated area.
