This paper studied methods of reclaiming and using the urban sewage heat energy, established the economic analysis model of the reutilization urban sewage heat energy based on the annual expenditures method, and presented the economic analysis of sewage source heat pump heating water system and other heating water system. It is shows that sewage source heat pump system with reclaiming the urban sewage heat energy has obvious effects of saving energy, economic and environment protection. It also points out that there is tremendous heat energy in the urban sewage, and the application prospect of the sewage source heat pump system are fine in China.
