Wind-magnetism pyrogenic water heater

The invention relates to a wind-magnetism pyrogenic water heater which comprises a vertical shaft-type S-shaped wind turbine and a pyrogenic device, wherein the upper cover and lower cover of the wind turbine are divided into two layers by a layering plate, and each layer is equipped with two semi-cylindrical blades; the openings of the two semi-cylindrical blades of each layer are opposite to form an S shaped, and a part of overlapping area is arranged on a rotating center; a water-storing tank and an accelerator are installed on a pyrogenic device support, and the input end of the accelerator is connected with the transmission shaft of the fan; and an output shaft passes through the bottom of the water-storing tank, a turntable provided with a permanent magnet is installed on the output shaft, and the bottom of the water-storing tank is connected with a heating plate. The water heater provided by the invention has the advantages that the wind energy conversion efficiency is high, the windward area is large, no requirements on the wind direction exists, and the eddy current pyrogenic efficiency of the pyrogenic device is high.
