摘要： A method of operating a tankless water heater for heating a continuous supply of water. The method includes detecting a water flow condition within a heating chamber of the tankless water heater and regulating electrical current to first and second heating elements in response thereto. Both the first and second heating elements are located in the heating chamber, and respectively have first and second wattages, where second wattage is different than the first wattage. The regulating step further includes providing electrical current to the first heating element and not to the second heating element when a first flow condition is detected, and providing electrical current to the second heating element and not the first heating element when a second flow condition is detected, and providing electrical current to both of the heating elements when a third flow condition is detected.

摘要： A temperature sensor securing system and method is described for securing two or more temperature sensors against an outer surface of a side wall of a tank of an electric water heater. The temperature sensors are secured spaced apart on an elongated support such as a circuit board which is held in position against the tank outer surface by support means. An expandable liquid foam causes the temperature sensors to be biased against the outer surface of the tank side wall to sense the temperature of the side wall at the location of the sensors and to generate actual temperature signals to a controller which is programmed to communicate with a subscriber and/or energy provider to control the water temperature inside the tank.

摘要： A hot water circulation system comprises a water heater having a cold-water inlet and a hot water outlet. A water pump circulates water through the water heater to produce hot water. The hot water is circulated to a thermal bypass valve, which is configured to close when hot water contacts a heat activated seal. A bypass circuit is coupled between the hot water outlet and the cold water inlet of the water heater. The bypass circuit prevents hot water from circulating from the hot water outlet to the cold-water inlet when the thermal bypass valve is open and promotes circulating hot water from the hot water outlet to the cold water inlet when the thermal bypass valve is closed. Upon a temperature sensor sensing hot water entering the cold-water inlet, the water heater turns of the water pump.
