The utility model discloses a quick electromagnetic induction water heater, which comprises a casing body (13), wherein the inner part of the casing body is provided with a water pipe (3), and the water pipe is connected with a spiral heating pipe (9). The lower part of the heating pipe (9) is connected with a hot water outlet (16), the outer part of the spiral heating pipe (9) is provided with a heat insulation layer (8) and an induction coil (7) which is connected with a power supply through a frequency conversion induction power supply (SB), and the upper part of the water pipe is provided with double filtering devices. The utility model is a heating device with the advantages of high thermal efficiency, fast temperature rising and obvious power saving efficiency. By utilizing the electromagnetic induction principle, tap water enters a metal heating device of a heating section after filtered by the double filters, and after frequency conversion induction, the power supply heats the spiral heating pipe of the heating device to form a vortex in order to quickly heat flowing water in a water channel so that hot drinking water and cool drinking water can be supplied to people.
