Many articles on the evaluation of heating methods have different evaluation angles, so the conclusions obtained cannot fully meet people''s different needs. To this end, this paper combines the AHP and the TOPSIS method to construct an evaluation index system to evaluate the comprehensive benefits of the "electric heating" project, and then obtain a comprehensive evaluation model, which demonstrates from the aspects of economy, comfort, reliability, and local policies. Analyze and evaluate the four commonly used electric heating methods to obtain an evaluation model of the optimal heating method in different regions, different climates, and different environmental conditions. Finally, take a city as an example to obtain the optimal heating for a city, and to get a general model for users to choose for reference.
