Abstract: An electric water heater having a water holding tank defined by a cylindrical side wall, a top wall and a dome-shaped bottom wall. A cold water inlet is disposed for releasing water under pressure in a lower portion of the tank. Two or more resistive heating elements heat water in an upper and lower region of the tank. The lower portion of the cylindrical side wall and the outer circumferential portion of the dome-shape bottom wall form a circumferential cavitated area inside the tank in which sediments deposit forming a bed in which bacteria can proliferate. A conduit is secured about at least a substantial circumferential portion of an outer surface of the cylindrical side wall adjacent the cavitated area. A resistive heating wire is disposed in the conduit and has connection leads extending out of a free open end of the conduit to an access area to provide connection to power terminals and a control for controlling the supply of power to the resistive heating wire.

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: 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: An electric water heater is described and wherein the bottom portion of the water holding tank is provided with various forms of electric heating elements to heat the water in the lowermost region of the tank adjacent the dome-shaped bottom wall to a temperature sufficient to prevent the proliferation of bacteria growth such as the Legionella bacteria in such lowermost region. The insulating foam support base of the water heater also provides a thermal barrier to the heating elements while biasing the heating element on the dome-shaped bottom wall in a region to insure excellent heat transfer to the cavitated zone surrounding the dome-shaped bottom wall where sedimentary deposits occur to create a culture medium for bacteria growth. In one embodiment a heating wire transfers heat to the lowermost region from the lower end of the surrounding side wall of the tank and access to the heating wire is provided for connection and removal thereof.

Abstract: A dielectrically insulated secondary tubular flue for mounting inside a water holding tank of a gas-fired water heater is provided to increase the efficiency of the water heater. The secondary tubular flue has opposed tubular end sections and an helical tubular section integrally formed therewith. The tubular end sections each have connecting end sections adapted to form a part of a dielectric connector for securing the secondary tubular flue inside of the water holding tank by the dielectric connectors.

Abstract: A double glass coated steel tank for a high temperature water heater and its method of fabrication is described. The tank is constructed of steel welded parts and fittings are secured to the tank without the presence of sharp edges being formed on the inner surface of the tank not to form any weakness in the composite glass coating to be applied. A first water resistant base coat of cobalt glass enriched with ZIRCON (trademark) is applied to the inner surface and the tank is heat fired at a high temperature in the order of about 1600 degrees F. A second high temperature water resistant glass coat, having a fine gas bubble size not exceeding 10 microns, is applied over the first coat and the tank is heat fired a second time. The composite glass coating thus formed is highly water and corrosion resistant in a water environment of up to at least 190 degrees F.
