<p>PURPOSE:To contrive to improve the electric power application efficiency by a method wherein the start of operation is controlled by calculating the starting time for energizing from the required energizing hour and the specified set time for hot water supply by means of an operating means. CONSTITUTION:The necessary heat quantity, the required energizing hour necessary for heating-up and the starting time for energizing proper for arranging load on the predetermined time zone are calculated by an operating means 15 from the temperature fed to a hot water storage tank 1 detected by a feed water temperature sensor 12, the temperature of residual hot water is the hot water storage tank 1 detected by a residual hot water temperature sensor 13, the amount of residual hot water and the like. When the starting time for energizing calculated by the operating means 15 is reached, the operating means 15 controls so as to stop the operations of a heating device 11 and a circulating pump 10. Due to the control as mentioned-above, no un-used hot water is left without being used for a long time, resulting in contriving to improve the electric power application efficiency.</p> |
