Abstract
An energy savings water heater is described. The water heater is controlled by an energy savings algorithm that uses one or more of a variable setpoint differential, a variable setback threshold, additional setback thresholds, and an adjustable minimal setpoint to improve the operation of an energy efficient water heater. Additionally or alternatively, a different setback control algorithm may be used that obtains additional data to adjust the setpoint. As a result, the operating cost of the water heater is reduced, while minimizing user complaints of cold water.
