The report describes laboratory testing and modeling exercises performed to assess potential heat pump water heater (HPWH) energy savings in the Pacific Northwest. Three integrated HPWH models, pairing two electric resistance elements with a tank-mound heat pump, were thoroughly investigated: the AO Smith Voltex, the GE GeoSpring, and the Rheem EcoSense.
