When the external water supply is insufficient, the lower water tank supplies water to the upper water tank for a period of time, and then gradually closes the electric heating electrode or waits for the external water supply to recover. This solves the problem that ordinary steam boilers cannot disconnect the electric heating device in the boiler in time when the water supply is insufficient, which can easily cause the water volume in the steam boiler to decrease rapidly and cause the electric heating electrode to burn out when the water supply is insufficient due to unexpected circumstances.
