摘要： 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.

摘要： 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.

摘要： A domestic gas-fired water heater condensing flue system wherein in one embodiment a blower is secured at the outlet end of the flue pipe to direct the hot flue gases through an external heat exchange flue conduit. The external heat exchange flue conduit has a sealed water channel surrounding a narrow flue gas internal passage. Water from the bottom end of the tank is circulated in the external heat exchange flue conduit and release in the top part of the tank. In a further embodiment, an inverted U-shaped flue pipe is supported vertically in the water tank and the domestic water supply for the tank is disposed in a downward section of the flue pipe to pre-heat the water supply to the tank and cool the flue gases before being released to atmosphere. The water in the tank is heated by the upward and downward sections of the U-shaped flue pie.

摘要： A pressure clamp adapter for mounting a thermistor on an existing thermostat control support bracket secured to a hot water tank spud is described. It comprises a thermistor bracket having a rear wall with opposed transverse projecting connecting arm formations extending from an outer surface of the rear wall. A cavity is formed from the rear surface of the rear wall to form a housing shaped to receive a thermistor therein. A passage communicates with the cavity. Each of the connecting arm formations is adapted for removable attachment to a pair of upwardly projecting legs of the thermostat control support bracket.

摘要： 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.

摘要： 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.

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.
