The Heat Pump Water Heater (HPWH) Subcommittee (formerly the HPWH Evaluation Subcommittee) was first formed in February 2012 as an advisory committee for regional HPWH evaluation. Since then the subcommittee has convened to discuss a variety of topics related to HPWHs, including baseline, HVAC interaction effects, and estimated savings. All meeting materials, including those from past meetings, are available below. Visit individual measure pages for more information on the RTF's current HPWH measures.
