Ductless Heat Pumps in Manufactured Homes, Multifamily, Single Family, Forced Air Furnace homes, and Small Commercial

The project is designed to test the ductless heat pump (DHP) in different applications. Fifty-one sites were installed to test different applications including single family, multifamily, manufactured homes , and small commercial across different climate zones. As part of the study, one year of data was collected through sub metering; and pre- and post-billing data were completed and analyzed for each site. Preliminary results have been promising for manufactured homes and single family homes with forced air furnace applications. The study was completed during the spring of 2013. Based on the findings of the study, Single Family and Manufactured Home applications provided sufficient energy savings to warrant presentation to the Regional Technical Forum as new measures in 2015. Both were given a provisional UES (deemed) measure status. DHPs in Manufactured Homes with zonal heat were given a Small Saver measure status.
