Rural No. 1 project has been steadily advancing, and a series of reform and innovation countermeasures such as coal-to-electricity, coal-to-electricity, coal-to-electricity, coal-to-electricity, and the use of new energy technologies have been vigorously developed, and all parts of the country are actively promoting the "Coal-to-electricity" project, so that a large number of rural people can enjoy the benefits of "Coal-to-electricity". The effectiveness of the "coal-to-electricity" project has been realized by a large number of rural people. Since China's gradual implementation of the current policy of banning coal, the use of which heating equipment into the focus of attention. The air energy heat pump can be used for heating, but also can be used to boil water, one machine for two purposes, energy saving and environmental protection. Once introduced, it quickly became a hot market for air energy heat pump circuit remodeling, and became the first choice for today's hot-selling renewal and remodeling. Now let's take a look at why air energy heat pump will become the first choice for coal to electricity conversion? For the uniqueness of the basic principle of the air energy heat pump heating system, I summarize the advantages of the air energy heat pump for you, so that you can grasp why the air heat pump water heater can become the first choice of heating equipment for "coal to electricity".
