Northern Climate Heat Pump Water Heater Specification

This specification provides guidance to manufacturers who are interested in developing products that not only meet ENERGY STAR criteria but are able to provide high levels of consumer satisfaction and energy performance in cooler, northern climates. The objective of this effort is to successfully accelerate the innovation and adoption of Heat Pump Water Heater (HPWH) products, with the end goal of HPWHs becoming the standard product for the electric water heating market.
