Abstract

PURPOSE:To lower the peak load of concentrated demands caused immediately after supply of midnight electricity is started, by calculating the total necessary time length required for obtaining a required quantity of heat, allotting it dividedly in the time range when midnight electricity is available, and utilizing the midnight electricity in accordance with the above allotment. CONSTITUTION:When the midnight electricity available time comes in the state that operation switch 12 is closed, operation circuit 14 is set into operation and calculates the amount of remianing hot water on the basis of temperature signals supplied from temperature sensors 7a-7d to operation circuit 14 via A/D converter 15. The operation circuit 12 calculates the total necessary time length and allotting it to a plurality of time regions obtained by dividing the midnight electricity available time, so that current is supplied to heater 2 via relay 16 consisting of coil 16a and contacts 16b in respective time regions allotted by an incorporated timer. In the above arrangement, a leak breaker 11 is provided between midnight power source 10 and relay 16 and a low-voltage power circuit 13 is provided between the power source 10 and operation circuit 14.
