Regenerative electric boilers are different. Regenerative electric boilers use low-valley power to provide heat during periods. Due to the low cost of ancient electricity and the development of mobile phone websites, the heating cost can be effectively reduced. As usual, thermal storage electric boilers are divided into two categories, one is traditional water thermal storage, and electric boilers are used in conjunction with heat preservation water tanks. Heat the water in the heat preservation water tank during the valley power, and then use the water area in the water tank to drive the whole heating system. This method is widely used in heat storage heating projects, but it is difficult to meet the actual situation in some projects because the insulation water tank occupies a large space, and it has the limitation of response. The second type is solid heat storage electric boiler, which uses heat storage bricks to store heat, effectively reducing the space occupied by equipment and realizing many projects, but the initial investment cost is slightly higher.
