    “A. O. Smith is once again proud to be a Platinum sponsor of the 2021 Hot Water Forum, which is the signature event for stakeholders in the water heating industry as well as those setting policy, regulations, and technological trends.” – Joshua C. Greene, Esq. Corporate Vice President – Government and Industry Affairs | A. O. Smith Corporation


    ACEEE hosted its 13th Hot Water Forum virtually with over 230 attendees, the preeminent annual conference on water heating. The event featured more than 60 speakers with a wide range of perspectives as well as plenaries, 16 break-out sessions, and networking opportunities throughout each day. In addition, we explored the impacts of the pandemic, the growing push toward grid decarbonization, and the electrification of homes and apartment buildings. Attendees also learned about the latest "quantum leap" technologies that are emerging across the industry, including heat pump water heater systems that use alternative refrigerants, are geothermal-enabled, and can function as batteries for energy storage.

    ACEEE thanks our sponsors and attendees for their support and encouragement in making our second virtual forum a great success. We also wish to thank the Hot Water Forum Steering Committee and the 60+ presenters and moderators whose commitment in time and preparation were greatly appreciated.

    The forum brought together a diverse group of 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, and consultants.

    Plenary Panels

    Efficient Hot Water Systems: Perspectives from Around the World - Wednesday, March 10

    This plenary discussed the potential impacts of incorporating water efficiency policies into codes and standards in India and South Africa that could result in a combined reduction of almost 90 million metric tons of carbon dioxide emissions each year. It also provided an update on the International Organization for Standards (ISO) working group, which is creating a worldwide standard on water efficiency products that will help developing countries reduce energy use and emissions. 



    Carrots and Sticks in Hot Water: The Heat Pump Water Heater Policy and Program - Wednesday, March 17

    This plenary explored the need for flexible loads on the grid, decarbonization policies at the city and state level, incentive HPWH programs in leading states (CA, WA) and nationally, and NBI's experience in leading the Advanced Water Heating Initiative (AWHI).
