HIGH FREQUENCY INDUCTION HEATING INSTANTANEOUS TANKLESS WATER HEATERS

摘要

A tankless water heater comprising a pipe, at least one coil around the pipe, at least one heating element located within the pipe and responsive to an electromagnetic field generated by the coil, and a controller to apply an alternating current (AC) signal to the at least one coil, the AC signal applied at a predetermined frequency and magnitude to cause the heating element to heat water flowing in die pipe to a predetermined temperature through induction heating.
