2025 ACEEE Hot Water & Hot Air Forums

ACEEE’s Hot Air and Hot Water Forums are devoted to heating energy market transformation. Since their founding in 2008 (Hot Water) and 2023 (Hot Air), the Forums have brought together seasoned experts and new voices to reduce the two biggest uses of energy in buildings.

Join ACEEE in 2025 to exchange knowledge on efficiently producing, distributing, and using hot water and decarbonizing space heating in buildings of all kinds through heat pumps. Both Forums explore how these industries can reduce greenhouse gas emissions, improve grid resilience, and center equity.

Previous 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.
