Ground-source heat pump systems have developed rapidly recently in China. This paper studies the feasibility of the Groundwater-source heat pump system used as heating system on the basis of an intended application on a university campus in Northeast China. The technical problems are discussed and it is found that all the technical matters can be solved. But the heating cost of heat pump system is doubled with comparison to the traditional heating system, i.e. district boiler plus radiators. Therefore, We believe groundwater-source heat pump system is not economical when it is used only or mainly for heating in Northeast China.
