NEEA’s largest emerging technology project, Heat Pump Water Heaters (HPWH), transitioned to full-scale market deployment after successful product and market tests. This milestone culminates four years of work to influence manufacturer and supply chain investment in HPWHs, and bring high-performance products for northern climates to the Northwest market. This achieves two-thirds of NEEA’s savings goal for technologies transitioning from the pipeline into full-scale market development.
