Central Heat Pump Water Heaters for Multifamily Supply Side Assessment Study

Report / January 10, 2023 / Building Innovation

The Northwest Energy Efficiency Alliance (NEEA) contracted with New Buildings Institute (NBI) in January 2021 to conduct research and outreach to better understand the current landscape of central heat pump water heater (HPWH) adoption in multifamily buildings. Research objectives included 1) Identifying all primary barriers to central HPWH adoption, 2) Increasing understanding of the value propositions (i.e., drivers) for each market actor in the central HPWH supply chain, and 3) Gathering market actor feedback to understand the most effective pathways to increased market adoption of central HPWHs. Research activities included fielding an online survey targeting specifiers and installers and conducting a series of interviews across the supply chain.
