Heat pump water heaters (HPWHs) are undoubtedly a promising pathway to sustainable, efficient hot water solutions. However, walking this path isn’t always easy, particularly for low-income housing communities.
Join us in this pre-HPWH Day panel of experts from the field of affordable housing providers. These leaders will be sharing their real-world insights on how to ensure not only a clean energy transition, but also a ‘just’ one. This session will focus on Central HPWH systems (CHPWHs) and cover experiences and learnings in implementing projects that switch from fossil-fueled water heaters to HPWHs, navigating installation and maintenance, securing diverse funding sources, and fostering stakeholder engagement at various levels, making HPWHs a part of a healthy, sustainable community life.

Central HPWHs typically store energy in large, insulated storage tanks full of hot water. While effective, storing hundreds of gallons of water takes up quite a bit of space. New innovations in phase change materials (PCMs), like glycol, allow HPWHs to conserve space and store even more energy. PCMs also enable higher temperature storage, providing additional hot water and improved load shifting capabilities.
