Heat exchange type electric water heater and water temperature control method of heat exchange type electric water heater

By setting up an instant heater and a water mixing valve in the heat exchange electric water heater, the cold water is initially heated and mixed with the cold water, and the heat exchange box absorbs voltage fluctuations, the temperature instability caused by the heating module is solved by the susceptibility to voltage fluctuations. The problem has achieved a stable supply of effluent temperature and improved the user experience.
