To provide a technology capable of informing a user about a recycling situation of exhaust heat without providing a temperature detecting means and a flow rate detecting means in an exhaust heat source and an exhaust heat recovering passage in an exhaust heat recycling system.
This exhaust heat recycling system includes a derivation determining device for determining derivation of heat used in heat load, and a display device for displaying a result of the determination by the derivation determining device. The derivation determining device determines the derivation of heat consumed by the heat load, to be an auxiliary heat source when an integrated value of heat supply amount in the auxiliary heat source is more than an integrated value of heat consumption amount in the heat load, and determines the derivation of the heat consumed by the heat load to be the exhaust heat source, when the integrated value of the heat supply amount in the auxiliary heat source is less than the integrated value of the heat consumption amount in the heat load. The derivation determining device starts integration of the heat supply amount from the auxiliary heat source and the heat consumption amount in the heat load from a time when the auxiliary heat source starts heating for securing a heat medium temperature necessary for the heat load.
