Already primed for heat pumps
The milder climate of the south means it is already well-primed for heat pump adoption. Encouraging greater heat pump adoption in the south will create the economies of scale for the heat pump industry to drive advancement in heat pump technology.
The figure below shows the projected heat pump adoption in the southern part of the region. On the left in the figure, the business-as-usual projection shows greater uptake of heat pumps in the milder climate of the southern region, with a corresponding decrease in natural gas appliances. In the milder climate of the southern region, the model also projects that advances in heat pump technology and linear heat pump performance in colder temperatures will substantially increase heat pump adoption in the southern region.
