AB - In order to contribute to widespread use of renewable energy sources in  Turkey, a solar-assisted ground source heat pump (SAGSHP) system was modeled  using TRNSYS software and simulated for heating and supplying daily hot  water to meet the needs of a restaurant in five sample provinces having  different climatic conditions. During the simulation, the dining room  temperature of the restaurant was kept constant at 22°C during the winter  season and a total of 300 L/h of water (55°C) was used for 15 min four  times a day. According to the simulation results, power consumption rates in  the SAGSHP system were determined as about 60% for the heat pump, 16% for  heaters, 14% for the ground pump and 8% for fans and other pumps. The  highest power consumption, as expected, was obtained for Hakkari Province  (6723 kW) in the Eastern Anatolia region, which has a cold climate, while  the lowest power consumption was obtained for İzmir Province (2822 kW) in  the Aegean region, which has mild climatic conditions. The lowest seasonal  performance factor (SPF) and solar factor (SF) values were calculated as  2.27 and 32% for Hakkari and the highest as 2.71 and 56% for İzmir,  respectively.
