PROBLEM TO BE SOLVED: To provide a hot water storage type hot water supply system which suppresses total electric power consumed by a plurality of hot water storage type water heaters in a concentrated load time zone when loads concentrate, to suppress a boiling amount as a whole system and to improve energy saving.SOLUTION: A hot water storage type hot water supply system includes: a plurality of hot water storage type water heaters; and control means which limits power consumption or heating capacity when each hot water storage type water heater performs a boiling operation in a concentrated load time zone, based on an allowable total electric power value which is total electric power which the plurality of hot water storage type water heaters are allowed to consume in the preset concentrated load time zone, and an assumed number of units of simultaneous operation which is the number of units of the hot water storage type water heaters assumed to perform the boiling operation simultaneously in the concentrated load time zone. |
