    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 hot water pulsating alarm system and method for electric or gas-fired water heaters is described. A sensor senses the water temperature in an upper region of the water tank of the water heater and feeds temperature signals to a controller. The controller operates an electromechanical valve connected to the pressurized cold water supply line of the water tank. Upon detecting a low temperature value stored in the memory of the controller, the controller causes a shut-off electro-mechanical valve to close and open in a predetermined sequence and during a predetermined time period. This causes interruptions of hot water being drawn from the upper region of the water tank to feed a hot water supply conduit and creating a pulsating water temperature change in hot water being discharged through fixtures connected to the hot water supply conduit. The pulsating temperature change is detected by a user person having a body part in contact with water dispensed from fixtures secured to the hot water supply conduit and indicating to the user person that the water heater will be shut-off.

    Abstract: A passage is provided in a water heater and mounted against the outer surface of the water tank side wall to removably mount thermistors secured to a support at distinct locations along the tank side wall to provide temperature value signal representative of the water temperature in the tank adjacent the thermistors. The passage may be formed by a metal tube held next to the side wall of the tank or a U-shaped channel held against the outer surface of the tank wall with the through thereof facing the tank side wall outer surface. The thermistors are mounted spaced-apart on a support inserted in the passage. The method is also described.

    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.
