JPS58130938A - Control device for hot-water reserving type water heater - Google Patents

Abstract

PURPOSE:To improve power transmission efficiency and reduce heat dissipating loss by a method wherein the proper necessary operating times of heating bodies, operated from the conditions of remaining water in respective hot-water reserving tanks, are distributed uniformly into the operating time bands thereof. CONSTITUTION:Respective hot-water reserving type water heaters 1, 1' are provided with amount of remaining water detecting meanses 2, 2', remaining water remperature detecting meanses 3, 3', operating means 4, 4', operating the amount of heat in the remaining water from the detected amount of remaining water and the remaining water termperature, operating meanses 5, 5', operating the amount of the heat to be applied from the amount of heat in the remaining water, operating meanses 6, 6', operating the necessary operating time of the heating body from said amount of heat, transmitting meanses 7, 7' for transmitting said necessary time to a central control unit 11 as a signal, and conduction control meanses 9, 9', while the unit 11 is provided with a receiver means 12, a time distribution control means 13 and a central transmitting means 14. The signals of the necessary operating times of respective heaters, which are being sent therefrom, are received by the means 12, all of the necessary operating times are integrated and the operating times of respective heaters are distributed properly by the means 13, thereby instructing the operating times from the means 14.
