Using borehole heat exchangers for heating and cooling in different climate conditions were analysed and compared in this paper, considering the heating and cooling modes of the heat pump. Economic analysis were made according to the energy demand for heating, cooling and hot tap water with borehole heat exchangers for a typical family house. The costs for running borehole heat exchangers in Macedonia and Poland were also based on the average monthly temperatures and geological profile of the location.
