Abstract
A water heater including a water reservoir container having a cold water inlet and a hot water outlet, a combustion chamber adjacent the water container, a burner associated with the container; a temperature probe associated with the container that detects a water temperature in an upper portion of the container, and a controller that activates the burner, the controller establishing an initial water temperature set point, comparing detected water temperature with the set point when the burner is activated, reducing the set point by a first selected amount when the water temperature decreases by less than a selected amount while the burner is activated or increasing the set point by a second selected amount when the water decreases by a selected amount of more while the burner is activated.
