The inherent design of many water heater thermostats has a built-in delay in responding to the water temperature in addition, intermittent short draws of a gallons or two of hot water by building occupants can cause cold water to be drawn into the bottom of a water heater causing the thermostat to cycle “on” and heat up the few gallons of cold water at the bottom of the tank.
