Weather forecast and prediction based temperature control
First Claim
1. A domestic water heating control system having at least one hot fluid delivery point disposed at a location, said domestic water heating control system comprising:
- (a) a controller adapted to control said domestic water heating control system to a setpoint temperature of the at least one hot fluid delivery point;
(b) a means for obtaining a forecasted outdoor air temperature at a future time at the location of said domestic water heating control system; and
(c) a means for obtaining a current outdoor air temperature at a current time at the location of said domestic water heating control system,whereby the setpoint temperature of said at least one hot fluid delivery point is configured to be adjusted by an adjustment amount if the difference between the forecasted outdoor air temperature at the future time at the location of said domestic water heating control system and the current outdoor air temperature at the current time at the location of said domestic water heating control system exceeds a pre-determined threshold.

Abstract
A weather forecast-based fluid heating control system having at least one hot fluid delivery point, the control system including a controller adapted to control a fluid supply to a setpoint temperature, a means for obtaining the forecasted air temperature at a future time of the location of the control system and a means for obtaining the current air temperature at a current time of the location of the control system. The setpoint temperature of the fluid supply is adjusted by an adjustment amount if the difference between the forecasted air temperature of the location of the control system and the current temperature at the current time of the location of the control system exceeds a pre-determined threshold.

7. A domestic water heating control system having at least one hot fluid delivery point disposed at a location, comprising:
-
(a) a controller adapted to control said domestic water heating control system to a setpoint temperature of the at least one hot fluid delivery point; (b) a means for obtaining and comparing forecasted outdoor air temperature at a future time at the location of said domestic water heating control system and a current outdoor air temperature at a current time at the location of said domestic water heating control system to result in a first difference; (c) a means for obtaining and comparing a forecasted wind chill factor at a future time at the location of said domestic water heating control system and a current wind chill factor at a current time at the location of said domestic water heating control system to result in a second difference; and (d) a means for obtaining and comparing a forecasted heat index at a future time at the location of said domestic water heating control system and a current heat index at a current time at the location of said domestic water heating control system to result in a third difference, wherein a sum of said first difference, said second difference and said third difference is configured to be calculated and whereby, if said sum exceeds a pre-determined threshold, the setpoint temperature of said at least one hot fluid delivery point is configured to be adjusted by an adjustment amount. - View Dependent Claims (8, 9, 10, 11)

- 12. A heating control method of a domestic water heating system disposed at a location, said method comprising a step of comparing a forecasted outdoor air temperature at a future time at the location and a current outdoor air temperature at a current time at the location, whereby if the difference between the forecasted outdoor air temperature at the future time at the location and the current outdoor air temperature at the current time at the location exceeds a pre-determined threshold, the setpoint temperature of the domestic water heating system is configured to be adjusted by an adjustment amount.
