An object of this invention is to provide a hot water supply apparatus capable of surely detecting human bodies in the bathroom. When a setting of a remote controller for kitchen is prior to a setting of a remote controller for bathroom, when a predetermined time for assigning the priority to the setting of the remote controller for bathroom comes, and when a loudness which is larger than a predetermined loudness is detected by a microphone of the remote controller for bathroom, the setting of the remote controller for bathroom becomes prior to the setting of the remote controller for kitchen. By this, the use of the bathroom is surely detected without a human body detector, such as infrared human body detector, provided in the bathroom. It is possible to avoid incorrect detections of the use of the bathroom. |
