This paper highlights a study for examining the viability and performance of a solar-assisted ground-coupled heat pump (SAGCHP) to meet domestic hot water and heating needs of a typical low-energy residential building covering a total floor area of 100 m 2 under Batna, Algeria, weather conditions. In this study, four different solar-assisted ground source heat pump combinations have been developed and will be simulated numerically using the simulation program TRNSYS. It turned out that a geothermal heat pump system of 7.7 kW, combined with flat solar thermal collectors, is an alternative promoter to achieve the objective of this study. The extreme annual average values of the heat pump coefficient of performance (COP) obtained are 3.48 and 4.55. In the system, with recharging the borehole, the net energy extracted from the ground is decreased by 30.4% compared to the reference case (GSHP). This can reduce the ground thermal imbalance problem.
