摘要： The disclosed technology includes carryover burner systems and methods for use with water heating system. The water heating system can include a burner unit having an outer sleeve, and an inner sleeve. The water heating system can also include an ignitor. The outer sleeve can include a carryover region having a first plurality of apertures and a combustion region which can be adjacent to the carryover region, the combustion region including a second plurality of apertures. The inner sleeve can comprise a dispersion region having a third plurality of apertures. The inner sleeve can be located substantially within the outer sleeve.

摘要： Disclosed herein is a water heating system including a water heater having a tank, and a first temperature sensor disposed toward a top end of the tank to measure a first temperature and a second temperature sensor disposed toward a bottom end of the tank to measure a second temperature. The water heating system can further include a controller communicably coupled to the first temperature sensor and the second temperature sensor, where the controller determines an amount of heated water in the tank based on one or more algorithms and measurements made by the first and second temperature sensors.

摘要： A combustion tube assembly of a water heater includes a combustion tube having an open end, a closed end, and an outflow opening located between the open end and the closed end. A cavity of the combustion tube provides a chamber for a combustion of a water heater fuel that produces an exhaust gas that flows down toward the closed end. The combustion tube assembly further includes a diverter structure positioned inside the combustion tube to divert the exhaust gas such that the exhaust gas flows toward the closed end on a first side of the diverter structure and flows from the first side of the diverter structure to the second side of the diverter structure through a flow opening proximal to the closed end. The outflow opening provides an outlet for the exhaust gas that flows to the second side of the diverter structure to exit the combustion tube.

摘要： 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.

摘要： A tube disposed in the combustion chamber of a standing pilot type fuel-fired water heater is used to increase the overall efficiency of the water heater by improving the heat transfer from the pilot flame to the tank during standby periods by funneling the standing pilot flame upwardly through the tube in a manner concentrating the pilot flame heat against an underside portion of the bottom head of the water heater tank. To further increase water heater efficiency, the pilot burner is of a dual input type. Various pilot burner operational algorithm modes are disclosed for causing the pilot burner to operate at a high firing rate during main burner operation, and at a low firing rate during standby periods.

摘要： The disclosed technology includes a combustion system providing ease of access to components of the combustion system and optimal placement of a burner such that efficient combustion and heat transfer can occur. The combustion system can include an inner tube having a first end and a second end, the second end having a flange with a sensor port, and an outer tube having a first end and a second end. The inner tube can be disposed within the outer tube. The inner tube can have an outer diameter less than an inner diameter of the outer tube, creating a gap between the outer tube and inner tube. An ignitor assembly and a flame sensor assembly can extend through the sensor port and the gap and be positioned proximate a burner.

摘要： A conduit fitting for an exhaust duct includes a conduit and a condensate trap. The conduit fitting defines an interior space partitioned into an upper conduit and a lower condensate reservoir. The condensate reservoir can be configured to contain a neutralizing agent for neutralizing acidic condensate prior to it exiting the reservoir.
