This study focuses on the economy of two renewable systems supplying the same demand of domestic hot water (DHW) and space heating (SH) for a city household located in Beijing of China. The systems are the solar thermal system and air source heat pump system. Both the two systems are considered for meeting the energy demand of SH and DHW. Optimized simulations are carried out to recognize the most economical configurations. The results show that, for a 15-year running time, the air source heat pump system comprising a 10 kW air source heat pump is the best configuration and has the minimum cost.
