Abstract
A water heater performs short-range wireless communication with an external device such as a mobile communication terminal in a manner that automatically authenticates the external device to be connected in response to establishment of communication connection. The transmission output of short-range wireless communication from the water heater is set to first output before establishment of communication connection with the external device, and is increased from the first output to second output when communication connection with the external device is established. Further, the transmission output of short-range wireless communication from the water heater is maintained at the second output and stands by for reconnection with the external device until a reference time lapses when communication connection with the external device once communicatively connected is disconnected, and is decreased from the second output to the first output when the reconnection is not established even after the reference time elapses.
