Installing HPWHs in Small Spaces: Lessons from the Amazing Shrinking Room

Learn how installation conditions directly affect heat pump water heater (HPWH) performance. Drawing from real-world “shrinking room” lab experiments, this session explores space requirements, venting strategies, and the thermodynamics behind them. Participants will gain practical design tools and actionable guidance to improve efficiency in both new construction and retrofit installations.
