The aim of this study was to adapt the operating parameters of a geothermal heat pump system to the required average power needed to meet the energy for central heating and domestic hot water of selected student residences. Calculations of the average power required by the dormitories in the AGH University Student Campus were carried out, as well as modelling of the deep borehole heat exchanger for the heating load. The designed heating system for the student residences in the AGH University Student Campus using a deep borehole heat exchanger - is sufficient to cover the base heat demand for five four-storey dormitories. During the writing of the paper, the main problem was the low availability of articles on deep borehole heat exchangers. This is due to the continuous development and testing of new engineering ideas. Deep borehole heat exchangers can be use as new boreholes or wells prepared for liquidation. Also use of closed boreholes sometimes is possible, depending on project of liquidation. The future districy heating will use low-temperature heat carrier for heating and cooling. Use borehole fields as rockmass use for heat and/or cool ,storage will be common.
