Over 40% of Midwest homes use delivered fuels or electricity as their primary heat source. Research continues to show that cold-climate air source heat pumps are ideal for these homes. Their capacity has improved over the last decade and they are capable of meeting a greater portion of the heating load. This presentation first discusses the ASHP research, including performance and capacity results, lessons learned, and experiences from over five years of detailed data monitoring from ASHP field installs. Based on the research, the presentation will also discuss quality installation, design optimization, and how to best integrate ASHPs into Midwestern homes. Finally, the presentation will highlight a few real-world installation examples in new construction. It will discuss the issues and benefits of ASHP system installs, an overview of mechanical systems and available performance metrics, and a discussion of ducted versus ductless use cases. It will also cover design and sizing considerations, key quality installation best practices, the ability to heat/cool different zones, plus overcoming market and technical barriers, first costs, and other considerations.

Learning Objectives:

Recognizing how critical quality installation is to ensuring ccASHP performance and learning quality installation best practices.
Learning ccASHP design optimization protocols.
Determining how to best integrate ccASHPs into existing homes’ heating and cooling systems.
Understanding the design and installation nuances of real-world new home applications of ccASHP.
