The total flow rate of the hot water flowing to a first heater core and a second heater core is controlled by a total flow rate control valve, and then the flow rate of the hot water to each of the heater cores is distributed by a distribution valve. According to this configuration, the flow rate of the hot water flowing through each of the heater cores is linearly controlled. Therefore, the heating of the driver's seat space by the first heater core and the heating of the air conditioning of the passenger's seat space by the second heater core can be linearly controlled.
