This paper investigates the seasonal performance of a combined solar, heat pump and ice storage system for residential dwellings. A simulation study is performed for seven different heat loads, i.e. building types, ranging from low-energy buildings to non-renovated existing buildings. Four reference buildings suitable for this heat generation system are presented and discussed in this paper. In addition, the solar ice system is applied to the three reference buildings defined in IEA HPP Annex 38/SHC Task 44 "Solar and heat pump systems". The simulation results show that the solar ice storage system generates heat efficiently for a large variety of heat loads and consistently reaches a seasonal performance factor comparable to heat pump systems with borehole heat exchangers, i.e. SPF ～ 4.
