PROBLEM TO BE SOLVED: To provide a hot water supply system preventing lowering of hot water temperature within a hot water storage tank even when a hot water use rate by a user is low. SOLUTION: A hot water supply system 1 for taking out hot water from a hot water storage tank 7 to which hot water is supplied from a water heater 2 for use by a user via a first going pipe 13a, includes a first hot water storage tank return pipe 14c, a reheating means 9 and a first control means 110. The first hot water storage tank return pipe 14c returns hot water delivered to the first going pipe 13a to the hot water storage tank 7. The reheating means 9 is interposed in the first hot water storage tank return pipe 14c. The first control means 110 controls operation/stop of the reheating means 9, based on at least one of hot water storage tank interior hot water temperature within the hot water storage tank 7, remaining hot water amount within the hot water storage tank 7, hot water supply amount of the water heater 2, hot water amount within the first going pipe 13a and hot water amount within the first hot water storage tank return pipe 14c.
