Find the most recent electric and natural gas Advanced Water Heating Specifications and all supporting documentation, including the Qualified Products List.
This System Requirements and Recommendations Summary provides manufacturers, designers and installers of very high efficiency DOAS systems with performance requirements and guidance for application in the Pacific Northwest climate zones. Additionally, the document provides design guidelines for added insight into the performance specification parameters and methods, and approaches for meeting corresponding requirements.
Pacific Northwest National Laboratory (PNNL) has teamed up with Bonneville Power Administration, Portland General Electric and other Northwest utilities to study the load shifting and #energyefficiency potential of heat pump water heaters. The results demonstrate that 90% of evening peak load power can be reduced by switching from uncontrolled electric resistance water heaters to connected heat pump water heaters, while reducing risks for utilities as well as costs to consumers.
This study considered small horsepower energy-efficient pumps, or “smart pumps": packaged systems consisting of a pump, variable speed drive and integrated controls. The report discusses how the alliance can continue to shape the market through activities such as documenting smart pump performance, providing targeted training to supply chain actors, and supporting increased communication among and between supply chain actors.
