20080173259 - High efficiency water heater: A high efficiency water heater comprising a generally cone shaped tank; an surrounding and spaced from the tank defining a passageway for flue gases between an inner surface of the enclosure and the outer surface of the tank, said enclosure having an outlet for flue gases; a burner communicating with... Agent: Blake D. Frasure

20080173260 - Heat transfer from a source to a fluid to be heated using a heat driven loop: Oil in a storage tank is heated by providing one or more elongate conduits within the storage tank in the form of a loop extending from an inlet manifold across the tank and returning to an outlet manifold. The inlet manifold is connected to an evaporator section at a heat... Agent: Ade & Company Inc.

20080173261 - Reducing heat transfer surface area requirements of direct fired heaters without decreasing run length: This invention relates to the design of direct fired heaters which consist of vertically oriented refractory lined enclosures containing tubular heat transfer elements, the elements partially surrounding a cluster of burners. The burners fire gaseous fuel and generate high temperature combustion products which allow for the transfer of heat ,... Agent: Alan Cross

20080168954 - Gas water heater having nitric oxide detector: A gas water heater includes a piping disposed in a housing for receiving a fluid to be heated, a gas burner for receiving a gaseous fuel and for generating a heat to heat the fluid flowing through the piping, and a regulating device coupled to the gas burner for adjusting... Agent: Charles E. Baxley, Esq.

20080168955 - Gas water heater having carbon dioxide detector: A gas water heater includes a piping disposed in a housing for receiving a fluid to be heated, a gas burner for receiving a gaseous fuel and for generating a heat to heat the fluid flowing through the piping, and a regulating device coupled to the gas burner for adjusting... Agent: Charles E. Baxley, Esq.

20080163832 - Boiler apparatus: To suppress corrosion of heat transfer tubes of a boiler under an influence of water, there is provided a boiler apparatus equipped with a unit for gathering boiler water (3) in a boiler 2 and a unit for adding the gathered boiler water (4) to supply water that has not... Agent: Birch Stewart Kolasch & Birch

20080156281 - Heating control system: A temperature regulation system operatively associated with a boiler is provided, including: a temperature sensor sensing hot-water restoration temperature of a space to be heated; a flow controller controlling the amount of restored hot water in the space; a hot-water restoration-flow detector detecting the amount of restored hot water flowing...
