Status and Prospects of Geothermal Heating in China

As an important kind of clean energy, the application of geothermal resources is becoming more and more widely in China, especially in the case of heating. Using geothermal resources to heating can reduce the pollution and help to change the energy structure. Most areas in China mainly use of fossil fuels for heating, but the pollution is serious and the heating situation is grim. But, the geothermal heating is the most direct using ways of geothermal resources.The history of using geothermal heating is more than 30 years in China, and the using of geothermal heating has begun to take shape in Tianjin and Xianyang. But it is limited by technical and cost constraints, the geothermal heating accounts for China's total heating area is still small. And the waste is serious in the process of using, so there is big development space for the using of geothermal heating in ourcountry. At present, the geothermal fluid heating(hot water heating) is the main heating way in China, the heating method of using ground-source heat pump is becoming popular. Although the hot dry rock heating is still in experimental stage, but it has a great spread future. After analyzing the history, current situation and prospects of geothermal fluid heating, ground-source heat pump method and hot dry rock heating, the suggestions for the future using of geothermal heating is proposed.
