In actual application, the water inlet pipe 21 of the circulation pump is first connected to the bathtub, and then the peristaltic pump 3 works first to suck the water in the bathtub and enters the heater 5 through the water outlet pipe 22 of the circulation pump for heating. When the circulation pump 2 is filled with water, that is, the air in the circulation pump 2 and its water inlet pipe is discharged, and the working conditions of the circulation pump 2 are met at this time. Then the circulation pump 2 is started to work and the peristaltic pump 3 is stopped. Then the water in the bathtub passes through the water inlet pipe 21 of the circulation pump, the water outlet pipe 22 of the circulation pump, the one-way valve 4, the heater 5, the one-way valve 4 and the heater 5 in sequence. The water inlet pipe 51 of the heater and the water outlet pipe 52 of the heater enable the water in the bathtub to be continuously circulated and heated, so that the user's bathing time is not restricted; by setting the above-mentioned structure, the utility model, on the one hand, replaces the self-priming pump with a peristaltic pump 3 to improve the life of the pump body itself, and on the other hand, optimizes the internal structure design of the electric water heater, arranges the circulating pump 2, the peristaltic pump 3 and the one-way valve 4 in the first installation space 12, and arranges the heater 5 in the second installation space 13, so that the circulating pump 2, the peristaltic pump 3 and the one-way valve 4 are not directly affected by the higher temperature of the heater 5, which can improve the service life of the circulating pump 2, the peristaltic pump 3 and the one-way valve 4, thereby increasing the service life of the electric water heater.
