Abstract：In order to evaluate the municipal electric heating system more objectively and comprehensively,this paper constructs a comprehensive evaluation index system considering the three factors of technology,economy and environment at the same time,improves the gray correlation analysis,and puts forward a comprehensive evaluation model of gray correlation analysis based on analytic hierarchy process-entropy weight method.To comprehensively evaluate the electric heating system of municipal heating,and to explore the factors affecting the technical,economic,environmental and comprehensive benefits of the electric heating and heating system.Using this model,an office district in Beijing is taken as an example to determine the optimal scheme of electric heating.The results show that the comprehen-sive benefit of heat pump+phase change heat storage system is the best,but the environmental benefit needs to be further improved.In order to promote the pace of electric heating,the government should increase the subsidy of electric boiler tech-nology.At the same time,clean energy power supply enterprises should improve the trading mechanism of electric heating market and reduce the price of clean energy heating.
