Provided is a fluid circulation system in which it is possible to reliably minimize any increase in room temperature unintended by a user and reliably minimize damage to heating devices due to the ingress of a high-temperature fluid. The fluid circulation system is provided with a heat storage circuit in which a fluid circulates between a fluid heater and a heat storage tank, a heating circuit in which a fluid circulates between the fluid heater and a heating facility, a valve for switching between the heat storage circuit and the heating circuit, an outflow temperature sensor for sensing the temperature of the fluid flowing out from the fluid heater, and a control device for controlling the switching between the heat storage circuit and the heating circuit. When a demand arises for switching from the heat storage circuit to the heating circuit during a heat storage operation in which the heat storage circuit is operated, the control device sets, as a criterion for switching from the heat storage circuit to the heating circuit, the temperature of the fluid flowing out from the fluid heater being lower than a reference value. |
