A hot water supply system includes a hot water supply device which can be connected to an external communication network via a communication repeater, and a server. The server obtains, in pairing processing of associating a mobile terminal device which can remotely control the hot water supply device with the hot water supply device, identification information of a communication repeater to which the mobile terminal device is connected, and stores the identification information along with pairing information. Besides, the server performs control to determine conditions of the remote control based on whether the identification information of the communication repeater stored in association with the hot water supply device being a remote operation destination matches identification information of the communication repeater received from the mobile terminal device in the communication, when the communication of the remote control is received from the mobile terminal device.
