Abstract
A water heater includes a storage tank, a sensor configured to measure a temperature of water in the storage tank, a burner configured to heat the water in the storage tank, and a controller communicatively coupled to the sensor and the burner. The controller is configured to initiate a call for heat when the measured temperature reaches a trigger temperature, wherein the trigger temperature is a differential amount less than a set-point temperature, calculate a reduced activation time when the call for heat results in a predetermined number of calls for heat occurring within a predetermined time period, and control the burner based on the reduced activation time.
