description PROBLEM TO BE SOLVED: To provide a hot water supply system capable of preventing hot water containing much contamination from being supplied from a hot-water storage tank, even if the hot water in the hot-water storage tank is not set to be periodically boiled. SOLUTION: A tank controller 50 performs sterilization processing by heating the hot water in the hot-water storage tank 31 by a heat pump unit 60, when a state that detected temperature of a hot-water storage thermistor 42 is the same as reheating determination temperature or lower continues longer than a reheating determination time. The tank controller 50 executes only heating temperature conditioning control while maintaining a hot-water amount variable valve 34 in a valve closing state, when a state that the detected temperature of the hot-water storage thermistor 42 is the same as stored hot water usage prohibition determination temperature or lower continues longer than a stored hot water usage prohibition determination time.
