Abstract of the Disclosure: A conventional hot water heating system generally of the type for heating water in multiple units of hotels, motels, schools and the like and using any heating medium has a processor and control assembly which is operationally connected to at least a water temperature sensing means and a heating control means thereof. The processor and control assembly divides the time into exact time periods, say one-half hour, and the time periods are grouped into a group of consecutive time periods, say a week. Taking any individual time period, the time periods are checked around the time period which the present time period is a repeat and time periods directly preceding the present time period, and the operational water temperature for the present time period is chosen, as well as the amount of heat required to maintain the water at that temperature on a percentage basis of heating taken from one hundred percent. In addition, the assembly exactly records the various settings throughout that particular time period and when the time period comes up again one week from now, the new settings are calculated in the same manner but using the previous time period being repeated. Still further, and assuming that the hot water heating system is of a particular water storage type, at any time that it is determined that the temperature at the beginning of the storage tank is indicating that the hot water is flowing from the outlet of that tank, and the water sensor at that point is not dropping in temperature so as not activating the heating control means, and when the temperature reaches a given lower temperature at the tank beginning, the heating control means is activated to begin heating of the water and will continue regardless of activation of the water temperature sensor means at the outlet of the tank, to thereby eliminate needless delays in heating of water. By the heating of water in the manner described, therefore, the maximum water temperature can always be maintained at a minimum and there is still relative assurance of a hot water supply at all times.
