In this paper, a modeling approach for comparing two heat-transfer-stations (HTS) is presented. By comparing a usual HTS with a modified HTS, where the return temperature on primary side of the district heating network (DHN) is used for heating the domestic warm water (DWW), it can be shown that utilizing the return flow of the heating positively contributes to a reduction of temperatures within a DHN and in this way saves exergy. The simulation model is implemented in Modelica.
