Publication number: 20030075118Abstract: The present invention is directed to a water heater that sustains energy during the standby mode so that it can power energy saving devices while e minimizing energy loss and controlling the stored water temperature. The present invention may include an outer casing, an insulated tank containing flue tubes, a combustion chamber, a burner rack containing a pilot and thermopile assembly a flue collector, a damper and a draft diverter. These components are preferably arranged to enable heat from the main burners to be transferred in an efficient manner to the water when needed and heat loss from the water to be minimized when the main burners are not fired. This may be accomplished without the use of external electric power, and the energy producing and heat transferring components of the water heater are optimally balanced, resulting in a sustained energy level that minimizes heat loss, prevents unwanted increases in water temperature, and enables the use of a damper without external electrical power.Type: ApplicationFiled: October 24, 2001Publication date: April 24, 2003Inventors: Eric M. Lannes, Garrett Doss

Publication number: 20030000484Abstract: A gas-fired water heater has a combustion chamber with a bottom wall defined by a perforated flame arrestor plate forming a portion of a flow path through which combustion air may be supplied to a burner structure within the combustion chamber. During firing of the water heater a combustion air shutoff system having a heat-frangible temperature sensing structure disposed within the combustion chamber senses an undesirable temperature increase in the combustion chamber, caused by for example a partial blockage of the flow path, and responsively terminates further air flow into the combustion chamber, thereby shutting down the burner, prior to the creation in the combustion chamber of a predetermined elevated concentration of carbon monoxide.Type: ApplicationFiled: July 22, 2002Publication date: January 2, 2003Inventors: Gordon W. Stretch, Bruce A. Hotton, John H. Scanlon, Gary A. Elder, James T. Campbell, Larry D. Kidd, Eric M. Lannes, James M. Martin, James W. Mears, Thomas E. Archibald

Patent number: 6422178Abstract: A fuel-fired heating appliance, representatively a gas-fired water heater, has a combustion chamber with an outer wall portion defined by a perforated flame arrestor plate having specially configured louvered combustion air intake openings through which combustion air is flowed into the combustion chamber. The louvered openings function to cause the entering combustion air to undergo directional changes as it inwardly traverses the openings and impart turbulence to the air entering the combustion chamber in a manner substantially inhibiting foreign matter blockage of the plate openings, providing an even combustion air inflow across the perforated plate area, and providing the plate with improved operational temperature uniformity along its sides.Type: GrantFiled: July 12, 2001Date of Patent: July 23, 2002Assignee: The Water Heater Industry Joint Research and Development ConsortiumInventors: Eric M.

Patent number: 6142216Abstract: An apparatus for heating a domestic water supply including a glass-lined storage tank for the domestic water supply and having a domestic water inlet port, a domestic water outlet port, and a heat-exchanging coil mounted therein. A heating tube is connected to the heat-exchanging coil to contain a recirculating fluid supply. The heat-exchanging coil within the glass-lined storage tank has a double-wall construction with a non-metallic outer wall in contact with a metallic inner wall. The double-wall prevents mixing of the domestic water supply with the recirculating fluid supply. The apparatus also includes a recirculating fluid heater positioned externally of the glass-lined storage tank to heat recirculating fluid to a temperature sufficient to heat the domestic water supply by heat transfer from the recirculating fluid in the heat-exchanging coil to the domestic water supply in the glass-lined storage tank.Type: GrantFiled: October 15, 1997Date of Patent: November 7, 2000Assignee: Bradford White CorporationInventor: Eric M.

Patent number: 5954492Abstract: The gas burner of the present invention includes a mated burner body and a burner lid. A plurality of gas ports in a substantially circular and planar arrangement are interposed between the mated body and lid and are directed radially from the body and lid. An air shield member is coformed to and extends radially from the burner body or burner lid. Extending radially from the air shield member in substantial radial alignment with the gas ports is a plurality of flame partitions equal in number to the gas ports. Each flame partition has two attached tabs which are substantially perpendicular to each other when the flame partition is observed in cross-section.Type: GrantFiled: February 20, 1998Date of Patent: September 21, 1999Assignee: Bradford White CorporationInventors: Eric M.
