| Abstract | One of the conditions for rationalisation of geothermal water use is to enable the most efficient heat transfer between geothermal water and municipal water. In district heating networks utilising geothermal heat it is important to bring the return water temperature from the heat installations of recipients to the lowest level, so that it could determine the temperature of pumped geothermal water. In order to fulfil that condition it is advised to implement predominantly low-temperature heat receivers or at least combination of recipients having high temperature installations with recipients having low-temperature installations, which enables effective cooling of municipal water. In this paper has been presented the method of assessment the possibility of extraction and utilisation of geothermal energy for selected district heating networks at combination of two groups of heat receivers with application of geothermal water heat exchangers. |
