Analysis for Marketization Development Prospect of Large-scale Solar Heating Combisystems in China

In recent years large-scale solar heating combisystems developed very faster in Europe and got better economical efficiency. In some countries such as in Denmark it seems that the solar district heating can have a clear future for marketing developing. However in China although development for solar water heating systems is to depend on the market requirement totally, but the case of solar heating combisystems is different with it. As more investment and longer pay-back years, the economical efficiency of solar heating combisystems is not very well now in China.In this paper it is given the background of development for large-scale solar heating combisystems in China, comparison of the different cases between Denmark and China and analysis for economical efficiency of large-scale solar heating combisystems in China. According to analysis and evaluation results China's marketing developing prospect of large-scale solar heating combisystems is given in the paper.
