The energy and exergy efficiencies of a Hybrid Ground-Coupled Heat Pump (HGCHP) system with Domestic Hot Water (DHW) supply are analysed based on experimental study. Comparisons between the HGCHP conventional DHW systems, i.e., Air Source (ASHP), Electric Heater (ElcH) Gas-Fired Boiler (GasB), made respect to efficiencies. results show that in highest efficiency, ranging from 6.7 2.1. In addition, possesses efficiency among four kinds heating systems.
