Advanced Water Heater Specification 

Utilities, energy efficiency organizations and market partners developed the Northern Climate Specification seven years ago to advance higher performing heat pump water heaters. An updated version of the specification has been released, and is renamed the Advanced Water Heater Specification.  

While this specification is rooted in ensuring performance in cooler northern climates, its applicability and benefits extend well beyond the Northwest. The updated specification also enhances the end goal of NEEA's HPWH program - to influence the passage of a 2025 federal standard requiring HPWHs for all electric storage tanks greater than 45 gallons in size. 


Lab Test Reports

These lab test reports inform the Qualified Products List for Heat Pump Water Heaters.
*Note: NEEA has tested numerous products for compliance, but does not claim to have tested all HPWH products that may be on the market. NEEA makes a determination regarding compliance to the specification based on available test results and product assessments. We encourage manufacturers to contact us with questions, and to report compliance testing via the Product Assessment Worksheet.
