HOT-WATER SUPPLY CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress low a meter-rate charge required for a boiling operation of a heat pump hot-water heater to be boiled while suppressing low daily maximum demand power in a hot-water supply control system for controlling a plurality of heat pump hot-water heaters.SOLUTION: Total power consumption for each time zone of any other electrical appliances than a plurality of heat pump hot-water heaters within a predetermined target area is predicted. A boiling operation of the heat pump hot-water heater to be boiled is preferentially executed in a time zone of a low meter-rate charge unit price within such a range that a sum of the predicted total power consumption for each time zone and power consumption for each time zone required for boiling the plurality of heat pump hot-water heaters becomes equal to or less than an upper limit power amount.
