With the deep development of clean heating in the north of China, distributed heat storage boiler is widely concerned as an important way of clean heating, which plays an important role in eliminating renewable energy and meeting the demand of residents' heating. It is a systematic project to eliminate and discard the light and wind from the distributed heat storage boiler, which involves many main bodies, such as power grid enterprises, heating enterprises, terminal users, renewable energy producers, etc., but the participation of all parties in the economic cost affects the promotion and effect of the spread of distributed heat storage boilers. Therefore, it is necessary to carry out the participation based on multi-party participation. The distributed thermal storage electric boiler is used to absorb the abandoned wind and discard light economy. In this paper, we summarize the typical business operating models, set up the economic cost analysis model of multi parties and take the method of combining qualitative and quantitative analysis to analyze the economy of the main participants, and finally give a typical example to analyze and evaluate the economy of all parties, which can provide references for clean heating price policy. 1
