Field and Lab Testing of Mitsubishi’s Prototype Ductless Heat Pump (DHP) plus H₂O Product for NEEA

Energy 350 was selected by the Northwest Energy Efficiency Alliance (NEEA) to conduct lab and field tests of Mitsubishi’s prototype Ductless Heat Pump (DHP) plus H₂O product. This product combines a ductless heat pump with a heat pump water heater into a single, integrated product. Energy 350 oversaw lab testing as well as conducted 13 months of field testing on 3 homes in Oregon; SW Portland, Gresham, and Bend.

Based on findings from the testing, a number of product improvements have already been implemented and additional product enhancements are underway.
