Abstract: A water heater appliance for a recreational vehicle is provided. The water heater appliance includes a cabinet, a heat exchanger positioned within the cabinet, and a combustion chamber positioned within the cabinet. The combustion chamber is in thermal communication with the heat exchanger. The water heater appliance also includes an exhaust tube fluidly coupled to the combustion chamber, and an exhaust box fluidly coupled to the exhaust tube. The exhaust box includes a first divider positioned in line with the exhaust tube, a second divider at least partially positioned below the exhaust tube, and an exhaust outlet positioned below the exhaust tube.

Abstract: A water heater for a recreation vehicle and method for control are provided. The water heater includes a tank including a plenum configured to hold water within the tank. A flue forms a flowpath including an inlet opening and an outlet opening. A flow control device is positioned to selectively allow flow through the outlet opening from the flowpath. The flow control device forms a closed position and an open position. A motor is operably coupled to the flow control device and configured to articulate the flow control device to the closed position and the open position.

Abstract: The gas fueled water heater appliance may include a tank, a chamber wall, a gas burner, a chamber sensor, and a controller. The chamber sensor may be configured to detect temperature within the combustion chamber. The controller may be mounted to the gas fueled water heater appliance in operable communication with the gas burner and the chamber sensor. The controller may be configured to direct a water heating operation. The water heating operation may include detecting an ambient temperature (AT) value during a contemporaneous cycle of the gas burner, selecting, based on the detected AT value, a set temperature threshold from a plurality of temperature thresholds, detecting a combustion chamber temperature (CCT) value at the chamber sensor during the contemporaneous cycle, comparing the detected CCT value to the set temperature threshold, and directing heating at the gas burner based on comparing the detected CCT value to the set temperature threshold.

Abstract: A water heater appliance may include a housing, a tank, a heating element, one or more temperature sensors, and a controller. The tank may be attached to the housing. The tank may define an interior volume. The heating element may be configured to heat water in the tank. The one or more temperature sensors may be attached to the housing. The controller may be mounted to the housing in operable communication with the heating element and the one or more temperature sensors. The controller may be configured to direct a water heating operation. The water heating operation may include directing a programmed diagnostic heating cycle, detecting an appliance temperature during the programmed diagnostic heating cycle, selecting an appliance model based on the detected appliance temperature, applying a predetermined model setting based on the selected appliance model, and directing a functional heating cycle according to the predetermined model setting.

Abstract: A water heater appliance for a recreational vehicle includes a tank and a flue disposed within the tank. The flue forms a U-shape that extends to and from an external side of the tank. A gas supply is in fluid communication with the flue. A burner assembly is disposed at an inlet of the flue. A baffle disposed within the flue. The baffle includes a plurality of restrictors configured to the baffle and the flue, and a flue collar mounted to the flue. The flue collar is configured to secure the baffle to the flue.

Abstract: A gas fueled water heater appliance may include a tank, a chamber wall, a gas burner, a chamber sensor, and a controller. The gas burner may be positioned adjacent to the tank and within a combustion chamber to heat water in the tank. The chamber sensor may be attached to the chamber wall. The chamber sensor may be configured to detect a temperature within the combustion chamber. The controller may be configured to direct a water heating operation that includes detecting a combustion chamber temperature (CCT) value during a contemporaneous cycle of the gas burner, determining a contemporary temperature-change rate based on the detected CCT value, comparing the determined contemporary temperature-change rate to a set rate, and directing heating at the gas burner based on comparing the determined contemporary temperature-change rate to the set rate.

Abstract: A water heater assembly for a recreation vehicle is provided. The water heater the assembly includes a tank including an interior configured to hold water within the tank. The tank includes an inlet opening configured to receive a first flow of fluid from an input conduit fluidly connecting a bypass valve to the tank. The tank includes an outlet opening configured to egress the first flow of fluid to a junction. A one-way valve is positioned fluidly between the outlet opening and the junction. A bypass conduit fluidly connects the bypass valve to the junction.
