The Economic Evaluation Research of Multi-Class Electric-Based Heating Mode in Non-Municipal Area

In order to promote the application range of electric-based heating, electric-based heating market can be applied to non-municipal areas, that is the area outside of heating coverage. The heating principle of several types of electric-based heating is briefly described, and the advantages and disadvantages of the single heating mode and the mixed heating system are analyzed. Through the investigation and calculation of the economic parameters such as the initial investment, operating cost and maintenance cost of each heating mode, and economic evaluation method such as net present value, dynamic investment payback period and net present value ratio is selected as the economic index, and then The Evaluation Index System of Heating Economy is established. Finally, combined with the example of electric-based heating pilot project, it is concluded that the mixed heating system has higher economic efficiency in the life cycle, which provides the theoretical support for the investment choice of the non - municipal heating mode.
