Air-to-Water Heat Pumps for Heating and Hot Water 101

Course overview:

This introductory session explores how air-to-water heat pumps can provide both space heating and domestic hot water using a single, integrated system. Participants will learn how these systems work, including the basics of hydronic heat distribution and high-temperature operation for compatibility with existing homes. The session will highlight where this approach fits best, including retrofit applications where maintaining radiators or baseboards is desirable. Through a lab-based demonstration with a real functional system on display, attendees will see key components, system layouts, and installation considerations. Builders will leave with a clearer understanding of opportunities, limitations, and what to look for when evaluating or specifying these systems.

Key learning outcomes:

• Describe in simple terms how an air-to-water heat pump can provide both space heating and domestic hot water.
• Recognize the basic components and layout of a typical system. Understand how these systems can work with existing radiators or baseboards in homes.
• Identify common situations where this type of system may be a good fit, especially in retrofits.
• Recall a few key considerations when encountering or discussing these systems on a project.

Key takeaways:

• This session will help builders better understand how integrated air-to-water heat pump systems work and where they make sense in real projects.
• It will strengthen their ability to identify opportunities, ask the right questions, and make more informed decisions when planning or evaluating heating and hot water systems.
