There are a great number of ground source heat pumps (GSHPs) have applied in China in the last decade with the help of academic study and governmental policy promotion. With a lot of large scale GSHPs applied without effective supervising, the market competition is in mess, and now they are facing a lot of complicated scientific problems and technological challenges. The practices show that the GSHP systems application should according to the terrain feature and season feature. This paper discussed the problems in the development and application of borehole ground source heat pumps and ground water heat pumps so that the GSHPs can develop effectively and healthily in China.
