Abstract

The present invention provides a method of preventing the occurrence of heating an empty electric water heater. When the temperature of a heat storage tank is detected to be lower than a pre-set low temperature, the heater performs heating for a pre-specified period of time and then stops heating. The variations of electric current during this period of time are compared with the variations of electric current during normal heating. If the differences are within a range of tolerance, the heater performs a normal heating procedure; whereas, if the electric current increases abnormally and falls outside the range of tolerance of normal heating electric current, the heater will not perform normal heating procedure, meanwhile, the heater displays abnormal codes or produces sound alarm to warn users. As a result, the safety of use of the electric water heater can be greatly increased to prevent the heater from being burned out. Furthermore, the detection of electric current is accurate and prompt without delay. Thus, the electric power to the heater is cut off before the temperature of the water heater has reached a specified value to protect the water heater and the safety of the whole electric water heater.
