Advanced Water Heater Specification

Advancing the market for HPWHs

Utilities, energy efficiency organizations and market partners developed the Advanced Water Heater Specification to advance higher performing 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 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.
