This project is a controlled field study and lab test that assessed the demand response (DR) potential of split system and unitary heat pump water heaters (HPWHs) that use carbon dioxide (CO2) refrigerant. The researchers included Washington State University (WSU), Pacific Northwest National Laboratory (PNNL), Efficiency Solutions, and Ecotope working with Cascade Engineering Services.
