Hot Water Forum Overview

ACEEE’s Hot Water Forum is the only technical conference about efficiently making, distributing, and using hot water, regardless of its source. Since 2008, the Hot Water Forum has brought together experts and novices from manufacturing, distribution (plumbing), electricity, gas and water utilities, government, and the research community to learn from each other and build momentum for market transformation. The Forum features two full days of sessions presented by experts in the field on cutting-edge development in these areas.

At this year's forum, over 250 participants had the opportunity to meet, share ideas, and learn from each other's latest efforts on research, new water heating technologies, structured plumbing approaches, new demand-reduction devices (e.g., fixtures and water-efficient appliances), and programs for stimulating market uptake of new approaches. 

Participants Included: Equipment and component manufacturers; water, gas, and electric utilities; local, state, and federal agency personnel; energy efficiency program planners, operators, and evaluators; plumbers and installers; policymakers; NGOs; and consultants.

Program

 

2018 Program Highlights
