Abstract: A hot water temperature sensing cut-off system and method for use with electric water heaters to preclude the flow of unsafe water from the water heater into the hot water distribution conduit to prevent the risk of bacteria transfer in the hot water distribution conduit. One simple solution is to mount a temperature responsive shut-off valve between the hot water supply outlet conduit of the tank of the water heater and the hot water distribution conduit and wherein the valve will shut-off water flow upon detection of an unsafe water temperature below 125 degrees Fahrenheit. Another solution is to use a controller to operate a shut-off valve. A temperature sensor is located to sense the water temperature at the intake of the hot water conduit and feeds a signal to the controller to operate a closure component of the valve to shut-off the hot water supply upon detecting a predetermined low water temperature fed to an inlet end of the control shut-off valve. When the water heats up to a predetermined safe temperature, the controller opens the valve and continues supplying hot water.

Abstract: 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.

Abstract: A method and an apparatus is described for preventing bacteria proliferation in a bottom end of a water holding tank of an electric water heater. Different water convection devices are described for convecting heated water from inside the tank and into the bottom end of the tank to raise the temperature at the bottom end sufficiently high to prevent bacteria growth and particularly at a temperature of at least 46 degrees C. where the Legionella bacteria can not survive. The temperature at the bottom end of the tank is monitored and the convection devices controlled to maintain the desired hot water temperature. An added benefit of the invention is that it also prevents sediment deposits and water temperature stratification in the tank bottom end section.

Abstract: An electrical water heater adapted for energy management and a method of controlling the consumption of electrical power from the power supply grid of a utility is described. The bottom resistive heating element of the water heater is a dual element resistive heating element which has a high power rated resistive heating element to heat water and a further low power rated resistive heating element. The power rating of the low power resistive heating element is calculated to be lower than the supply grid diversified mean load. A controller has a communication link with a utility which manages the power supply grid. The utility can control the resistive heating elements of the dual element in such a way, and depending on conditions of the grid, to conserve energy and regulate its frequency thereby resulting in a cost saving to the consumer and the utility. The low power rated resistive heating element is also connectable to an alternative power source.

Abstract: A fluid conduit dielectric nipple for securement to a tank wall of a fluid holding tank, such as a steel tank of a water heater is described. The fluid conduit dielectric nipple has a tank securement end and a cylindrical conduit connecting end specifically configured for receiving a push-fit quick connector to secure to a water supply line and a hot water return line. The fluid conduit dielectric nipple is fabricated from inexpensive metal, such as plated steel, and has a plastics liner to protect parts thereof intended to be exposed to water to prevent corrosion while providing a leak-proof connection. Accordingly, there is provided an inexpensive dielectric nipple which provides quick connection and disconnection.

Abstract: A water holding tank for electric water heaters is described and particularly an improvement to the bottom end construction of the tank to prevent bacteria proliferation and the elimination of the cavitated circumferential area where sediments deposit to form a culture bed for bacteria to proliferate. Instead of modifying the shape of the bottom wall the improvement is a simple solution in that a filler material is set in at least a lowermost portion, and preferably a major portion, of the cavitated circumferential area to isolate that area from the interior of the water holding tank and form smooth flat surface areas which are planar to cause sediments to disperse and not form beds for bacteria to proliferate.
