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.
