In this paper presented are the results of analysis of utilisation the geothermal energy in a geothermal heat plant supplied with the mean-enthalpy geothermal water. This heat plant is equipped in geothermal heat exchanger, absorption heat pump and peak load boiler and co-operates with low- and high-temperature heating systems connected in series. In such installation acquisition of geothermal energy takes place by means of the heat exchanger, which transfers heat from geothermal water to the municipal water with a simultaneous use of a heat pump. A role of a lower reservoir in the heat pump is played by a part of return municipal water, which decreases its temperature with respect to the kind of used heat pump and in relation to the temperature of return municipal water. Supplementary to that installation is a peak-load boiler assuring (in the case of such necessity) heating up of feeding municipal water to the required temperature.
