Consortium for Energy Efficiency: Controls for a Heat Pump with Secondary Heating (for Contractors)

Audience: Contractors

Prioritizing heat pumps in a residence that uses two heating systems can minimize the use of fossil fuels to reduce the carbon footprint of a home, while maximizing savings and comfort. Learn how two-system controls can reduce callbacks for contractors and make operation easier for homeowners who use more than two heating types. Other topics include when two-system controls should be installed, how to configure them, control strategies, how to determine switchover temperatures using different types of fuels, and balance points.
