Issues of obtaining energy and its sources for many reasons are the subject of research in many places. Energy heat pump systems based on borehole heat exchangers are used as research installations in many universities on the world. The examples are installation in University of Ontario Institute of Technology [3]. The UOIT borehole thermal energy storage system has almost 400 boreholes each over 200 m deep. Borehole fields also are spaced around the campus of Ball State University. The fields contain a series of closed pipes that are installed vertically in the rock-mass. Ball State’s loop consists of approximately 3600 boreholes, 122–152 m deep. The boreholes are 4–5 inches in diameter. During Phase 1, 1800 boreholes were drilled. Phase 2 will include the drilling of 1800 additional boreholes, ending with more than 1610 km of geothermal piping installed [1]. On VSB-Technical University of Ostrava exists also laboratory BHE field [2]. The installation at the Geoenergetics Laboratory of the Faculty of Drilling, Oil and Gas AGH UST allowed the authors to investigate heat resources for their regeneration capacities in the rock mass [5]. The system is equipped with five borehole heat exchangers performed in 2008 [4], and making up a Borehole Thermal Energy Storage (BTES). Then, the installation for measuring heat regeneration was gradually developed. In 2010 it was connected to the Auditory hall owned by the Faculty of Drilling, Oil and Gas, and located between buildings A3 and A4. The old ventilation system was substituted with a new one, thanks to which the heat could be recuperated. This was the first stage at which the air temperature was changed. At the second stage the temperature was
