HOT WATER STORAGE TYPE EXHAUST HEAT RECOVERY SYSTEM

PROBLEM TO BE SOLVED: To provide a hot water storage type exhaust heat recovery system exercising superior heat efficiency by maintaining a temperature of hot water stored in a hot water storage tank in a full state at maximum. SOLUTION: The hot water storage tank 14 is provided for storing hot water heated by a heating means 11 in a form of forming thermal stratification, a supply intermitting means 18 is provided for intermitting supply of the hot water from the heating means 11 to the hot water storage tank 14, and a supply state control means 22 is provided for controlling operation of the supply intermitting means 18 such that hot water wherein a supply hot water temperature of the hot water supplied from the heating means 11 to the hot water storage tank 14 is a target hot water storage temperature or more is supplied to the hot water storage tank 14 when the hot water storage tank 14 is a non-full state. It is composed such that when the hot water storage tank 14 is a full state, the supply state control means 22 controls operation of the supply intermitting means 18 such that hot water wherein the supply hot water temperature becomes a stored hot water temperature or more of the hot water stored in the hot water storage tank 14 is supplied to the hot water storage tank 14.
