Paper shows the performance analysis of the boreholes being the lower heat source for the brine-to-water heat pump. Researchers focused on the changes of the specific power extraction rate change in time and in various loads. The measurements were the continuation of the analysis of the differences between the Thermal Response Test (TRT) and exploitation data made in 2016/2017 heating season. The heat source performance under greater load and in longer period have been examined. The analysis showed brine temperature drop in overload work conditions even when ambient temperature was high and severe heat source destabilization despite a return to original performance.
