This research project will assess air-to-water heat pump (AWHP) retrofits in existing and new construction residential single family and multifamily buildings in Wisconsin. The first phase of the project will consist of identifying buildings, sourcing bids on system design, and modeling energy savings. The second phase of the project will consist of installation and monitoring of the AWHP systems which will be used to develop a workpaper for future offerings. Comprehensive findings from the research will be shared in a final report.

An air-to-water heat pump is an electric heating system that pulls heat from the outside air and transfers it to the water pipes that deliver heat to radiators and in-floor radiant systems, doing the work of a boiler or geothermal system. They can operate at up to 500% efficiency and can work in tandem with a backup boiler, saving substantial amounts of energy and potentially reducing energy costs. Air-to-water heat pump systems have been used in Europe for years and are already gaining traction in the Northeast of the U.S.
This research is currently in the outreach phase and looking for owners of single-family homes or multifamily properties in Wisconsin to participate in our study of this next-generation air-to-water heat pump technology, ready to perform in cold Midwest winters.
Take the opportunity to heat your home with one of the first air-to-water heat pump systems deployed in Wisconsin, paid for in full by Focus on Energy. You will play a crucial role in this field study by giving feedback on your satisfaction with the system and allowing Focus on Energy to monitor the system as it heats your home. By participating, you contribute to advancing the understanding of air-to-water heat pump technology and its applications in Wisconsin’s colder climates.
