| Zusammenfassung: | The invention relates to a power saving control method and device for electric water heater that adds two power saving mode of high temperature and low temperature holding temperature to water heater. It detects the water temperature in water storage tank and judges which mode would be executed. By observing the declining speed of water temperature, the first power saving mode or the second power saving mode would be judged. The invention could determine heat time for electric water heater to achieve power saving effect. |
