Water heater with power consumption reporting

摘要

A hot water heater and method that includes power consumption reporting to enable consumers to better understand and control the energy usage and/or efficiency of the hot water heater. Monitoring energy consumption of an electric hot water heater having at least one electrical load that is selectively activated by a controller of the hot water heater includes sensing the amount of time the at least one electrical load is activated multiplying the amount of time by a known value corresponding to a power rating of the electrical load to determine energy consumed, and displaying on a display device an indicator corresponding to the energy consumed. 10 COLD HOT WATER WATER INLET OUTLET SENSOR UNIT 16 MEMORY SENSOR CONTROLLER Fig.I
