System and method for control of heat system operation by changing a switching set point of operation
First Claim
1. A method for control of a heating system having a heat pump and supplemental heating, via a computer system, comprising:
- at least periodically receiving data relating to current prices of at least one of electricity prices and prices of a source of said supplemental heating, the source of said supplemental heating being oil or gas; and
automatically changing a switching set point in response to price changes in at least one of said electricity prices and prices of said source of said supplemental heating, wherein said switching set point is a temperature at which said heating system switches between operation of said heat pump and operation of said supplemental heating;
wherein said switching set point temperature is increased as said electricity prices increase relative to said prices of said source of said supplemental heating, and wherein said switching set point temperature is decreased as said electricity prices decrease relative to said prices of said source of said supplemental heating; and
switching between operation of said heat pump and operation of said supplemental heating based on said switching set point.

Abstract
There is provided a space heating system (100) that includes a heat pump (105), a supplemental gas heating system (110), and a controller (115) connected to the heating system (100). The controller (115) controls a switching set point, which in its simplest case is an ambient temperature at which the controller (115) switches between operation of the heat pump (105) and operation of the supplemental gas heating system (110). The controller (115) is connected to a real time source of information (195) providing at least one of current electricity prices and current prices of a source of heating such as gas, and changes the switching set point in response to changes in at least one of the electricity prices and the gas prices. There is also provided a method for control of the heating system (100).
