Water heating device and faucet

The utility model relates to the technical field of continuous flow heaters. The water heating device and the faucet comprise a first pipe body, an electromagnetic coil, an iron heating body and a rust-proof heat conductor, the electromagnetic coil, the iron heating body and the rust-proof heat conductor are all arranged on the first pipe body, the iron heating body senses a magnetic field generated by the electromagnetic coil, and the rust-proof heat conductor isolates the iron heating body from an inner cavity of the first pipe body. Due to the fact that electromagnetic heating is fast, water in the inner cavity of the pipe body is heated in an electromagnetic heating mode, the purpose of instant heating can be achieved, and when the water pipe head is used, the water pipe head is installed at a water outlet of a faucet, and water flowing out of the faucet can be heated in real time. Besides, the iron heating body is isolated from the inner cavity of the first pipe body by adopting the rust-proof heat condu
