Further, the inner wall of the heat storage water tank 112 is made of 304 stainless steel, the outer wall of the heat storage water tank 112 is made of color steel plates, a polyurethane heat insulation layer is arranged between the outer wall of the heat storage water tank 112 and the inner wall of the heat storage water tank, and the thickness of the polyurethane layer is 60 mm.
Furthermore, the pipe type electric heater 150 and the built-in ceramic electric heating pipe 111 both adopt ceramic heaters, the ceramic heaters are efficient and distributed heaters with uniform distribution, the heat conductivity is excellent, the temperature of a hot surface can be ensured to be uniform, hot spots and cold spots of equipment are eliminated, and the ceramic heaters have the advantages of long service life, good heat insulation performance, strong mechanical performance, corrosion resistance, magnetic field resistance and the like.
Further, the terminal heating equipment used in the room is not limited to the radiator 160, and a fan coil may be used.
Further, the data transmission is not limited to the GPRS wireless transmission module 310, and Wi-Fi and broadband networks of residents may be used.
Further, the number of the pipe-type electric heaters 150 is 1, and the heating power is 3 kw; the number of the built-in ceramic electric heating tubes 111 is 2, and the heating power is 1.5 kw. The pipeline type electric heater 150 and the built-in ceramic electric heating pipe cannot be started at the same time, and work in different periods, so that the impact on the power grid is effectively reduced, the original power grid does not need to be improved, and the initial investment cost is reduced.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
