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 gas water heater appliance includes a tank for storage of water for heating, a combustion chamber wall positioned below the tank and defining a combustion chamber and a pilot air inlet, a gas burner positioned within the combustion chamber to heat the water in the tank, and an arrestor assembly mounted to the combustion chamber wall above the pilot air inlet and below the gas burner. The arrestor assembly includes a flame arrestor and a restrictor plate positioned adjacent the flame arrestor, the restrictor plate defining a bottom of the combustion chamber and comprising one or more apertures that provide fluid communication between the pilot air inlet and the combustion chamber.

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 may include a housing, a tank, a refrigeration system, and a controller. The tank may be attached to the housing. The tank may define an interior volume. The refrigeration system may include a sealed refrigerant loop in thermal communication with the tank to heat the interior volume. The controller may be operably coupled to the refrigeration system. The controller may be configured to direct a heater operation. The heater operation may include determining a voltage input for the water heater appliance, selecting, based on the determined voltage input, an operational mode from a plurality of predetermined mode options that include a high-voltage mode and a low-voltage mode, and directing the refrigeration system according to the selected operational mode.

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.
