Pilot project in Seattle shows central heat pump water heaters can act as massive hot water batteries that help reduce carbon emissions
Central heat pump water heaters (CHPWHs) present a tremendous opportunity to reduce the substantial energy used for water heating and can act as giant thermal batteries. They do this by using energy to heat water during times of low grid demand and storing it for later use, enabling them to limit their energy use during peak times on the electricity grid. Leading organizations in the Advanced Water Heating Initiative (AWHI)’s Commercial Working Group are showing the grid asset implications in the first of its kind Bayview Tower pilot project in Seattle.
The CHPWH system was installed in 2021 and proved its ability to work well while saving energy. Then the team moved into phase two of the project, which proved that the CHPWH can provide significant load shifting capacity.
As more wind and solar energy comes online and as our communities, regions, and states electrify buildings and transportation, the times we use electricity become increasingly important. Using less electricity during peak times, storing energy, and shifting energy usage over time are key strategies – and smart heat pump water heaters can do all of them. Read blog post here
TECH Clean California is co-presenting with the ENERGY STAR HPWH Manufacturer Action Council (ESMAC) in upcoming Heat Pump Water Heater Education webinars
These are free and open to anyone interested in learning about HPWHs. Each session is a live two hour webinar focused on HPWH technology features and benefits, appropriate applications, energy efficiency compared to other water heater types, installation techniques and best practices, service support and warranty, proper maintenance, troubleshooting, and selling strategies. The ESMAC team will transition to training contractors participating in the California Self-Generation Incentive Program (SGIP) launching in June. This training will include additional emphasis on connectivity and demand response readiness. Learn more here
