The Building America Partnership for Improved Residential Construction, led by the Florida Solar Energy Center, investigated the effect of ducted and interior-located heat pump water heaters (HPWHs) on space-conditioning energy use and water-heating energy use in a study conducted in Brevard County, Florida during 2013-2015. A growing volume of research shows that HPWHs have the potential to save significantly more site and source energy than other electric-storage water-heating options, but little research has been done to meter potential positive / negative impact on space conditioning energy.
