2024 Hot Water Forum & Hot Air Forum

March 12 - 14, 2024

    Hilton Atlanta | Atlanta, GA

    The 2024 Hot Water Forum (HWF) is the premier technical conference dedicated to efficiently producing, distributing, using, and reusing hot water. Since its inception in 2008, this two-day conference has brought together seasoned experts and newcomers to exchange knowledge, foster innovation, and help drive market transformation.

    In addition, ACEEE presents the second Hot Air Forum (HAF), focusing on decarbonizing space heating in buildings of all kinds through heat pumps. Both conferences will explore how these industries can reduce greenhouse gas emissions, improve grid resilience, and center equity.

    The HAF will kick off the event in Atlanta, Georgia, from March 12 to 13, then transition to the HWF, March 13 to 14. The events will overlap on the 13th, a full day of collaborative sessions covering the intersections between space and water heating. 

    Previous HWF/HAF gatherings have attracted diverse attendees, including equipment and component manufacturers; water, gas, and electric utility professionals; and local, state, and federal agency representatives. Energy efficiency program planners, operators, evaluators, electricians, plumbers, installers, policymakers, representatives from NGOs, engineers, consultants, and other experts have found value in the sessions and great networking at the events.

    These two conferences have separate sponsorships, with a 50% discount on the second sponsorship for companies supporting both events. Please get in touch with Alan Raymond for more information. 

    Join us in shaping the future of hot water and space-heating efficiency at the 2024 HWF and HAF conferences.
