CONTROL DEVICE OF HOT-WATER STORAGE TYPE ELECTRIC HOT-WATER HEATER

摘要

PURPOSE:To contrive to supply every day the amount of hot-water responding the actual requirement of an user by a method wherein a memory device stores the up-to- date data of the amount of heat for the amount of hot-water as the past actual consumption results, and an electric power to be supplied for a heating body is determined based on said data. CONSTITUTION:A time switch 8 is made ON (4), the control is started simultaneously with the energizing, at first, the maximum value KGmax is called (5) from among the up-to-date data by a memory device 12, a necessary amount of heat presetting device 13 presets (6) the necessary amount of heat KS after mutiplying the KGmaz by the constant C including the margin. A heating temperature presetting device 14 measures (7) the hot-water supply temperature Ti in a hot-water storage tank 1 with a temperature sensor 9, presets (8) the heating up temperature To based on the capacity Vt of the hot-water storage tank. Therefore, the presetting heating temperature preset for each hot-water heater is inputted into a central control device, which outputs the energizing start signal to each heater for levelling of load through the entire time zone of the midnight electric power supply service time zone based on the required heating up temperature of hot- water. Thus, the energizing for the heating body 5 is started after receiving of each energizing start signal.
