2026 Hot Water & Hot Air Forums

Keeping homes and other buildings warm in winter and providing hot water represents more than half of U.S. buildings’ energy use. ACEEE’s Hot Water and Hot Air Forums showcase how efficiency reduces this energy use, and corresponding utility bills and peak electric loads. The Forums bring together equipment manufacturers, utility program managers, implementers, and researchers in an engaging, collaborative space to discuss strategies that work.

By attending, you will learn about the latest technologies, their performance in the lab and under real-world conditions, and ways that utilities and policymakers are speeding their adoption. As heating air and water requires so much energy and is so intertwined with daily life, driving down costs and ensuring households have a positive experience with these technologies is crucial.

We will highlight customer concerns as well as the voices of those who work directly with customers, such as installers. Attendees will benefit from opportunities to hear from industry leaders, connect with the whole community at multiple breaks and receptions, and see products and speak to manufacturers in person.
