<p><P>PROBLEM TO BE SOLVED: To provide an operation plan generating device for a storage type electric water heater capable of preventing the occurrence of hot water shortage in the daytime and improving COP. <P>SOLUTION: This operation plan preparing device comprises a heat consumption predicting means for computing predicted heat consumption of each unit time zone of a planned time zone based on the result value of heat consumption of each time zone in the past stored in a heat consumption storage means; a heat storage amount detecting means for measuring an initial heat storage amount; and a heat supply time zone determining means for determining a heat supply time zone based on the initial heat storage amount and the predicted heat consumption of each unit time zone. The heat supply time zone determining means determines a heat supply time zone so that the heat storage amount of a hot water storage tank is not less than a minimum heat storage amount in the planned time zone and that the start time of the heat supply time zone is the latest. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
