Water Heater Demand Response: Comparing Full Replacement and After-Market Controllers

Posted November 14, 2022 By Eileen Hannigan Shannon Kahl Pace Goodman

In this whitepaper presented at IEPEC in 2022, ILLUME shares the results from Phase 1 (of 2) for a water heater demand response (DR) pilot. During Phase 1, the pilot evaluated full-unit water heater replacements and found measurable impacts between the summer and winter demand response events. Read the paper to learn more about the impact of load shift events, customer experience, and how Phase 1 informed the design of Phase 2 which installed after-market controllers on water heaters.
