The objective of the research is to forecast baseline heat pump water heater sales in the Northwest -- Idaho, Montana, Oregon, and Washington. Specifically, we estimated the unit sales and installations of heat pump water heaters meeting the Tier 1 and Tier 2 Northern Climate Specification, above and below 55 gallons, in absence of utility incentive programs.
