Abstract
A water heater including a storage tank including a water inlet and a water outlet, a pump, an upper temperature sensor, a lower temperature sensor, and an electronic processor. The electronic processor is configured to receive an upper temperature signal and a lower temperature signal, compare the upper temperature signal to a sum of a setpoint temperature threshold minus a temperature differential, and compare the lower temperature signal to a high limit temperature threshold. The electronic processor is further configured to activate the pump in response to the first upper temperature signal being less than the sum of the setpoint temperature threshold minus the temperature differential and the first lower temperature signal being less than the predetermined high limit temperature threshold.
