WEBINAR: CARD Air-to-Water Heat Pumps: A cold climate solution for high-efficiency cooling, space heating, and water heating


Air-to-water heat pump (AWHP) systems are a flexible type of air source heat pump that could extend heat pump savings to more customers and integrate hot water loads. However, with this flexibility comes complexity that may hinder adoption of this new technology. In response, Center for Energy and Environment shared research results in this webinar to fill knowledge gaps and provide context to AWHP systems for Minnesota consumers. System configurations for serving heating, cooling, and hot water loads in cold climate single-family homes will be clarified based on recent market research.

The strengths and weaknesses of commercially available AWHPs will be uncovered further by examining detailed field monitoring results of four AWHP retrofits in Minnesota. These field results provide real-world data on the cost-effectiveness and energy saving capabilities of AWHPs in cold climates.

This project was supported by a grant from the Minnesota Department of Commerce, Division of Energy Resources through the Conservation Applied Research and Development (CARD) program.
