FINAL REPORT: Optimized Installations of Air Source Heat Pumps for Single-Family Homes

This study installed a sample of all major types of cold climate air source heat pump (ASHP) systems in homes, developing interim protocols for system selection, configuration, sizing, control, and integration with backup heat, then implemented, refined, and validated those protocols. Field data was collected and analyzed to assess heating performance, comfort, and customer acceptance, and to provide reliable real-world savings data from cold climate ASHPs.
