2023 Hot Water Forum & Hot Air Forum

March 7 – 9, 2023

    DoubleTree by Hilton San Diego | San Diego, CA

    The 2023 Hot Water Forum (HWF) comes at a critical—and promising—time. The emergence of new water-heating technologies combined with the investments in building decarbonization and workforce development made by the Infrastructure Investment and Jobs Act and the Inflation Reduction Act creates the opportunity for significant market transformation. This is a pivotal moment for the hot water industry to reduce greenhouse gas emissions, improve grid resilience, and center equity.

    In addition, ACEEE presents the inaugural Hot Air Forum (HAF), which will focus on decarbonizing space heating given the monumental federal funding opportunities. This forum will precede the HWF and include a day to discuss the crossover between space and water heating.

    Likely participants: Equipment and component manufacturers; water, gas, and electric utility professionals; local, state, and federal agency personnel; energy efficiency program planners, operators, and evaluators; plumbers and installers; policymakers; NGOs; engineers; consultants; and other experts.

    Registration and lodging information will be available mid-December.
