An improved heater and method of controlling the same is provided. The water heater has the combination of a tank for holding water, a heater for heating the water, a controller having logic to regulate the heater, and first and second sensors. Each of the sensors detects the water temperature at different areas within the water heater. The sensors also provide the controller with signals corresponding to the detected water temperature. In response to these signals, the controller regulates the heater when at least one of the signals of the first and second sensors satisfies at least one predetermined state condition.
