NBI installed 120-volt HPWHs for 32 customers in most climate zones across California (CA). The units were monitored for water and ambient temperature, flow rate, power consumption, and the customers and contractors were surveyed on their usage and satisfaction with the water heaters. Once the fundamental features and the water heater capability to provide hot water were successfully validated, three of the 32 sites were selected to test the water heater demand response readiness and load shifting features to confirm whether they were able to follow schedules, preheat water, and store water. This effort is part of the Advanced Water Heating Initiative (AWHI), a national market transformation effort to decarbonize water heating in buildings. This study was made possible with funding from Pacific Gas and Electric, Southern California Edison, Sacramento Municipal Utility District, TECH Clean California, and Pacific Northwest National Laboratory.
