An integrated valve and flow sensor for a water heater can have a valve body that includes a valve and a flow sensor for measuring the flow of water through the valve. The integrated valve and flow sensor can be disposed within a fitting that can be attached to a water heater. An actuator for opening and closing the valve can be attached to the fitting. A diffuser can also be attached to the fitting.

A water heater includes a leak detection system that is integrated with the water heater. The leak detection system includes a channel that extends circumferentially around the water heater. In one example, the channel is built into the water heater. In another example, the channel is formed by a sensor bracket that is coupled to the water heater. Further, the leak detection system includes a sensor assembly that is configured to detect water that leaks from the water heater. The sensor assembly includes a leak sensor and/or a wicking tube. The wicking tube is disposed around at least a portion of the leak sensor. Further, the wicking tube is disposed in the continuous channel and extends circumferentially along the water heater to create a circumferential area of leak detection around the water heater.

A motor/damper assembly installable on the top end of a fuel-fired water heater includes a support plate structure upon which a flue collar with a pivotally supported flue damper, a drive motor, and a drive shaft interconnecting the motor damper are mounted. The assembly is installed by placing the collar over the upper end of the water heater flue, securing the support plate structure to the top end of the water heater, and positioning a top cover housing on the support plate structure. Using the assembly provides improved support rigidity and alignment for the motor and shaft relative to the damper, improved repeatable precise manufacturing placement of the motor and shaft, improved construction aesthetics, with the cover also protecting the shaft from shipping and handling damages.

An electric water heating apparatus includes a first electric water heater having a first tank adapted to hold a quantity of water and a first electric heating structure disposed within the first tank. The electric water heating apparatus further includes a second electric water heater having a second tank adapted to hold a quantity of water; and a second electric heating structure disposed within the second tank. The electric water heating apparatus further includes a control unit that is in electrical communication with the first electric heating structure and second electric heating structure, the control unit configured to prevent both the first electric heating structure and the second electric heating structure from being simultaneously operable.

Stackable water heater apparatus

Water heater apparatus is provided with features that allow for a horizontally compact water heater installation comprising upper and lower vertically stacked electric individual water heaters served by a single electrical branch circuit. Each of the upper and lower water heaters has a water storage capacity not exceeding 55 gallons, and the combined water storage capacity of the upper and lower water heaters is greater than 55 gallons. The electric heating elements of the two water heaters are non-simultaneously controlled so that at no time do the two water heaters heat water at the same time.

A gas burner cap for a cooking appliance includes a top side and a bottom side. The bottom side of the cap is configured to face a corresponding burner body. One or more flame-stabilization chambers are located on the bottom side of the cap.

Burner cap flame stabilization chamber

A burner assembly for a gas powered cooking appliance is provided. The burner assembly may include a burner body including a central region and a plurality of radiating extensions extending radially outward from the central region. The burner assembly may include a burner cap with a central region and a plurality of radiating extensions extending radially outward from the central region. The burner cap is positioned on top of the burner body when the burner is assembled. The burner cap may include at least one overhang positioned on the outer perimeter of the central region and between an adjacent pair of radiating extensions. The at least one overhang forms a gap between the exterior wall of the burner body and the interior wall of the overhang. This gap, or flame stabilization chamber, provides for collection of gases and flame that aid in maintaining the flame during low temperature operation.

A fuel-fired water heater is provided with a combustion chamber assembly, representatively a sealed combustion chamber assembly, operative to create from combustion air delivered thereto via a circumferentially limited vertical side portion thereof a flow of primary combustion air to the underside of a centrally disposed fuel burner within the assembly via a first location underlying the burner, a first flow of secondary combustion air delivered to the burner via the first location, and a second flow of secondary combustion air delivered to the burner via a second location outwardly circumscribing the first location.

Portion of a burner assembly

A radiant burner within the combustion chamber of a fuel-fired water heater is supplied with primary and secondary combustion air from outside the combustion chamber. A flame-holding mesh section of the burner is protected from becoming unacceptably clogged by particulate matter in the primary combustion air by causing the incoming secondary combustion air to flow sequentially through a finer mesh section and a tapered duct which increases the velocity of the secondary combustion air before causing it to impinge upon and cool a temperature sensor connected to a controller. Clogging of the finer mesh section decreases the cooling of the temperature sensor, thereby causing the controller to terminate operation of the burner before it becomes unacceptably clogged.
