ADAPTIVE HEATING CONTROL SYSTEM FOR A WATER HEATER
First Claim
1. A water heating control system for automatically reducing delay in delivering a volume of water at a flowrate, the volume of water is heated from a first temperature to a target temperature during a time interval of a day, said water heating control system comprising:
- (a) a device for aiding in heating the volume of water at said flowrate from said first temperature to said target temperature;
(b) a historical flow demand corresponding to the time interval of a day;
(c) a current flow demand corresponding to the time interval of a day; and
(d) a controller configured for calculating a new flow demand based on said historical flow demand and said current flow demand,wherein if said new flow demand exceeds a threshold, said device is configured to be activated during the time interval of a day and said new flow demand is configured to be set as said historical flow demand for the time interval of a day.

Abstract
A water heating control system for automatically reducing delay in delivering a volume of water at a flowrate, the volume of water is heated from a first temperature to a target temperature during a time interval of a day, the water heating system includes a device for aiding in heating the volume of water from the first temperature to the target temperature, a historical flow demand corresponding to the time interval of a day, a current flow demand corresponding to the time interval of a day and a controller configured for calculating a new flow demand from the historical flow demand and the current flow demand. The new flow demand is set as the historical flow demand for the time interval of a day and if the new flow demand exceeds a threshold, the device is configured to be activated during the time interval of a day.

10. A water heating control system for automatically reducing delay in delivering a volume of water at a flowrate, the volume of water is heated from a first temperature to a target temperature during a time interval of a day, said water heating control system comprising:
-
(a) a device for aiding in heating the volume of water at said flowrate from said first temperature to said target temperature; (b) a historical flow demand corresponding to the time interval of a day; (c) a current flow demand corresponding to the time interval of a day; and (d) a controller configured for calculating a new flow demand based on said historical flow demand and said current flow demand, wherein said new flow demand is configured to be calculated by applying a first weighting factor to said historical flow demand to result in a first intermediate result and a second weighting factor to said current flow demand to result in a second intermediate result, wherein said second weighting factor is a complementary percentage of said first weighting factor, wherein if said new flow demand exceeds a threshold, said device is configured to be activated during the time interval of a day and said new flow demand is configured to be set as said historical flow demand for the time interval of a day. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
