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 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: A dual energy gas water heater is described and wherein a square flange, curved resistor style resistive heating element, is secured in a bottom portion of the tank of the water heater spaced above a top wall of the combustion chamber. A gas burner is secured in the combustion chamber and connected to a gas supply line through a gas valve. The curved resistive heating element is a low density, long life, element having a density in the range of about 20 to 80 watts/sq. inches. A switch is secured between the thermostat of the resistive heating element and the voltage supply line. A controller selectively operates the switch and the gas valve to disconnect the voltage supply line from the thermostat and/or shut-off the gas valve secured to the gas supply line depending on the desired source of energy. The controller is adapted to be optionally controlled by a utility/provider through a communication link. Renewable energy source may also be secured to an additional resistive heating element to improve the efficiency thereof.
