Ductless Heat Pumps

Measures include DHP for homes with zonal electric heat or electric forced air furnace as their primary system. These measures are available for existing single family and manufactured homes. Qualifying applications include the following:

1. Single-family residences with zonal electric heat, including zonal electric hydronic systems. For electric hydronic upgrades, claim as zonal if heat distribution is through in-floor radiant or wall radiators, and claim as Existing Forced Air Furnace if distribution is through a duct system.
2. Single-family residences with electric forced air furnaces, with or without air conditioning.
3. Manufactured homes with zonal electric heat.
4. Manufactured homes with electric forced air furnaces, with or without air conditioning.
5. Ductless heat pumps must be a split system heat pump employing inverter driven outdoor compressor, with inverter-driven or variable-speed indoor blowers, rated with a minimum of 9.0 HSPF (for single head systems) and listed on BPA’s DHP Qualified Product List.
6. Ductless heat pumps must be installed on a dedicated electrical circuit, according to manufacturers’ specifications and the Best Practices for Installing Ductless Heat Pumps Guide, by a HVAC company who attended a Northwest Ductless Orientation.
7. Ducted indoor DHP units do not qualify for Payment as a Ductless Heat Pump (DHP) but may be claimed as a PTCS Variable Speed Heat Pump provided the installation meets all PTCS requirements.
8. Mini-Splits include both ductless mini-split head(s) as well as ducted mini-split(s). A ductless mini-split head has an indoor wall-mounted inverter driven unit (air handler) that is not connected to ductwork. A ducted mini-split (also referred to as short-run ducted or a ducted ductless) has an indoor inverter-driven (variable speed) unit (air handler) that is connected to ductwork.
