Abstract
A method for determining whether hot water is used during heating of an air handler system which uses a water heater as a heat source and supplies hot air through a duct for heating is disclosed. The method includes: (a) detecting a flow rate change of tap water supplied to the water heater; (b) detecting a temperature change of the tap water supplied to the water heater; and (c) determining that hot water is used during heating when the flow rate change of the tap water in step (a) and the temperature change of the tap water in step (b) are detected at the same time.
