The present invention relates to a heat medium supply facility provided with a control means for controlling the operation of the heat source machine.

Such a heat medium supply facility operates a heat source device and supplies a heated heat medium to a terminal device such as a floor heating device or a bathroom heating dryer through a heat medium circulation path.
In such a heat medium supply facility, air may enter the heat medium circulation path from a pipe member or a joint portion that forms the heat medium circulation path, and when the amount of air that has entered increases, Heat medium circulation failure that makes it impossible to circulate properly, or heat medium leakage that the heat medium flows out of the expansion tank that is open to the atmosphere in the heat medium circulation path for absorbing the heat medium expansion occurs.

That is, the air venting operation is executed by the control means in a preset time zone and every preset period.
And since the sound and vibration which generate | occur | produce with an air venting operation can be set as the said setting time slot | zone in a time zone (for example, midnight time zone) where it is difficult for a user to recognize, an air venting operation is performed. It is possible to suppress discomfort to the user due to the accompanying sound and vibration.
Accordingly, it is possible to provide a heat medium supply facility capable of performing an air vent operation while suppressing discomfort to the user.
