Scheduled hot water heating based on automatically periodically adjusted

Abstract

A conventional hot water heating system generally of the type for heating water in multiple units of hotels, motels and the like and using any heating medium has a processor and control assembly operationally connected to at least a heating control means, a water temperature sensing means and a water flow sensing 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, a directly preceding time period is checked with the same time period in the preceding group of time periods and if the two match within a given degree, the assembly adopts all of its settings from its particular time period a week ago. In addition, the assembly exactly records the various settings throughout that particular time period and when that time period comes up again one week from now, those are the new settings by the processor and control assembly to be used. Still further, at any time in a time period that high hot water flow from the water tank is detected by the water flow sensing means and the heating control means has not yet begun to begin heating more hot water, the water flow will immediately turn on the heating control means to thereby eliminate needless delays in the 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.
