20060150925 - Water heater with pressurized combustion: A water heater includes a sealed combustion chamber and one or more fans for raising pressure in the combustion chamber to increase efficiency of the water heater. The pressure permits a more restrictive baffle to be used in the flue compared to baffles used in atmospheric water heaters. The water...

20060150926 - Flammable vapor sensing control for a water heater: A method of controlling a gas-fired water heater. A resistance input is received from a sensor configured to sense flammable vapor near the heater tank. The resistance input is compared to one or more previously received inputs from the sensor. Based on the comparing, one or more functions of the...

20060150927 - Dual function high efficiency water heater: This gas-fired water heater has a shell sealed at opposite ends within an insulated storage tank, defining a water-tight chamber with inlet and outlet water connections thereto. The shell preferably is a one-piece casting of aluminum alloy, with a circular array of impervious passages between its opposite ends. Each passage...

20060144346 - Insulation kit for use with a water heater: An insulation kit for use with a water heater is provided. The kit includes an insulating cover configured to be wrapped about an exterior surface of the water heater. The insulating cover includes a substantially rectangular body with opposed edges configured to overlap or abut one another when the insulating...

20060144347 - Heat exchanger suitable for a boiler, and a boiler including such a heat exchanger: A heat exchanger comprising: gas flow path means for defining a flow path for flue gases from a boiler; liquid flow path means for defining a flow path for a liquid through the heat exchanger; and heat transfer means for transferring heat from the gas in the gas flow path...

20060144348 - Heat recovery steam generator: In accordance with one embodiment of the present invention, a first vessel for holding a mixture of steam and water is disclosed. At least one first manifold is in fluid communication with the first vessel, the at least one first manifold is for receiving water from the first vessel. At...
