PROBLEM TO BE SOLVED: To provide a waste heat collecting system capable of collecting and using a collectable amount of heat generated in a heat source more than before. SOLUTION: When the heat amount collectable from the heat source surpasses the usable heat amount of a waste heat boiler 16 when steam is generated by collecting waste heat from an engine 10 used as a heat source in the waste heat boiler 16, the system is switched from a water supply tank side preheat circulation system for waste heat boiler to a water supply tank side preheat circulation system, water is passed therethrough, and excess heat is collected on the water supply tank 34 side. As a result, a heat amount surpassing the usable heat amount in the waste heat boiler 16 among the heat amount collectable from the heat source can be collected on the water supply tank 34 side for effective use.
