The thermoelectric boiler is a kind of heating appli⁃cation equipment which can converse electrical energy into heat ener⁃gy storage, used to supply heat to the users or other heat energy appli⁃cations. Its structure is simple, but the thermal efficiency can reach about 95%. Peak load shifting through heat storage can reduce thermal power load of thermal power unit, improve the utilization rate of wind power to a large extent, and solve a large scale energy loss caused by the wind farm "waste wind" electricity. The article introduces the working principle of solid energy storage heating unit, analyzes its eco⁃nomical efficiency and stability. By comparing with gas, the paper ex⁃pounds the characteristics of the energy storage heating unit product.%蓄热电锅炉是一种能够将电能转化为热能储存，用于向热用户采暖或作为其他热能应用的设备，其结构较为简单，热效率却能达到95%左右。通过蓄热调峰可以减轻火电机组采暖负荷，提高风力发电利用率，在很大程度上解决了由于风电场“弃风”限电导致的大规模能源损失问题。介绍固体蓄能供热装置的工作原理，分析其经济性及稳定性。通过与天然气对比，阐述蓄热装置生产的特点。
