Electric boilers have been used in China for less than a decade. As a kind of home heating method, electric boiler has been widely used in North China, Northeast China and Northwest China in recent years. At present, the electric heating area of Beijing has exceeded 10 million square meters, and the Beijing Power Bureau has announced some preferential policies for the electricity price of electric boilers, that is, the use of peak and valley electricity prices, and the valley price is halved to only 0.20 yuan/KWH. Other regions such as Liaoning, Heilongjiang, Inner Mongolia, Shaanxi, Xinjiang, Shandong and other provinces have also introduced relevant preferential policies to try out differential electricity prices for users using vacuum boiler efficiency electric boilers, so that users using electric boilers can get benefits, and reduce the burden on users through preferential electricity price policies.
The heating cost of electric boilers is roughly the same or slightly lower than that of central heating, and from the point of view of economic use, all imported electrode boiler users accept the price of electric heating. The vacuum boiler standard is to further improve the thermal efficiency, reduce the power and equipment costs of the unit, improve the operational flexibility and automation level of the boiler unit, develop more varieties to adapt to different regions, and improve the operational reliability of the boiler unit and its auxiliary equipment. It can control environmental pollution, energy saving and emission reduction will be the most powerful development highlights of electric boilers.
