20100269345 | MEMBRANE SEAL FOR WATER HEATER TANK SPUDS - A method of manufacturing a water heater includes the steps of providing a water heater tank having an interior and an exterior, the tank also including a first aperture communicating between the interior and exterior, providing a spud having an internally threaded aperture and placing a membrane between the spud and the tank such that the membrane covers the first aperture. Thereafter, the method also includes the steps of welding the spud and the membrane to the tank, and thereafter forming a second aperture in the membrane so that the threaded aperture of the spud communicates with the interior of the tank via the first and second apertures. | 10-28-2010 |
20100077969 | METHOD OF WATER HEATING AND DISTRIBUTION - A method of storing water at two temperatures, the method comprising: providing a tank divided into first and second chambers; storing water in the first chamber at a first temperature; storing water in the second chamber at a second temperature; heating water in the second chamber when the second temperature is below a predetermined second value; pumping water from the second chamber to the first chamber when the first temperature is below a predetermined first value, the first values being less than the second value; and permitting water flow from the first chamber to the second chamber while pumping water from the second chamber to the first chamber. | 04-01-2010 |
20090241858 | WATER HEATER WITH HIGH EFFICIENCY BAFFLES - A water heater for exchanging heat between hot gasses and water within the water heater. The water heater includes a water tank, a conduit for allowing flow of the gasses therethrough, the conduit extending through the tank and promoting heat exchange between the gasses and water in the tank, and a baffle extending within the conduit for affecting the flow of the gasses. The baffle includes a sheet bent in a zig-zag manner and having a number of plate sections. Each plate section has a through-flow portion allowing the gasses to flow therethrough. The sheet also has a number of first bends and a number of second bends, the first bends alternating with the second bends such that each plate section is defined between one first bend and one second bend. | 10-01-2009 |
20090179025 | RESISTOR ANODE ASSEMBLY - A sacrificial anode assembly. The sacrificial anode assembly includes a sacrificial anode, an insulator positioned around an end of the anode, an electric coupler positioned around the insulator and extending beyond the end of the anode, the electric coupler electrically isolated from the anode, a resistor having a first lead and a second lead, the first lead electrically connected to the anode and the second lead electrically connected to the electric coupler, and a cap positioned around the electric coupler, the cap electrically connected to the electric coupler and electrically isolated from the anode. The cap complete encapsulates the resistor, the first lead, and the second lead. | 07-16-2009 |
20080232977 | Pump Control - A pump control system for controlling a fluid pump powered by an AC signal. The pump control system includes a signal phase detector coupled to the fluid pump to detect the AC signal supplied to the fluid pump and to generate phase signals indicating a phase parameter of the AC signal. The pump control system also includes a micro-controller to receive the phase signals and to generate a rectified output signal based on the phase signals, and a relay to control the power supplied to the fluid pump based on the output signal of the micro-controller. | 09-25-2008 |
