Utilities, energy efficiency organizations and market partners developed the Advanced Water Heating Specification to advance higher performing electric and gas heat pump water heaters. While this specification is rooted in ensuring performance in cooler northern climates, its applicability and benefits extend well beyond the Northwest. The specification also enhances the end goals of NEEA's water heating programs - to influence the passage of federal standards requiring heat pump levels of performance for both gas and electric storage water heaters.
The latest version posted below is the AWHS 8.0 and is a draft that includes a new specification section for Commercial Heat Pump Water heaters. Additionally, NEEA is starting to have conversations about adding Industrial Heat Pump Specification in the next version (9.0) of the AWHS.
The document has been slightly reorganized, however, the Residential (Section 1 of the new specification) is unchanged. Version 8.0 of the AWHS is planned to go live 1/1/2022. Please reach out to Geoff Wickes at NEEA to provide suggestions and insights if you have any concerns (503.688.5456).
