In papers [11, 12] presented have been the results of investigations concerning the manufacturability of underground dosed geothermal heat exchanger (UCGHE) from the technical and economic point of view. Above mentioned geothermal heat exchanger forms one of the elements of the binary power plant. In the latter paper presented are the results of selected numerical calculations of UCGHE. On the other hand, in the present paper presented are the results of calculations obtained using the analytical model for calculations of UCGHE [7], where utilised have been known relations enabling calculations of variable in time, overall thermal resistance or the overall heat transfer coefficient from the rock massif to the heat carrier.
