Project Title
CHPWH Unpressurized Storage Design Optimization
Project Number ET23SWE0059 Organization SWE (Statewide Electric ETP) End-use Water Heating/DHW/HPWH Sector Commercial Project Year(s) 2023 - 2024Project Results
Central heat pump water heaters for multifamily and non-residential buildings have become a high-priority technology for energy-efficiency and decarbonization programs in recent years. There are many completed and in-progress projects aimed at understanding, development, adoption, and program opportunities for this important measure. Manufacturers, researchers, end users, and program administrators are all eager to find paths towards increased cost-effectiveness and adoption of these systems. One such opportunity is to reduce the first cost of the products through simplification of the thermal energy storage volume of these systems. To that end, unpressurized storage has been proposed as a way to reduce first costs and expand market options.
