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.
