Ductless heat pumps are split system, air-source heat pumps with variable cooling and heating capacity. High part-load efficiencies, flexible zoning and no duct losses mean ductless heat pumps could be a cost-effective way to save on heating and cooling in commercial buildings. The 2015 ductless heat pump pilot is being updated to accommodate multi-head unit systems as well.
Energy Trust is conducting this pilot to learn more about ductless heat pumps in commercial buildings and is offering a cash incentive of $800 per outdoor unit for qualifying projects that meet the following criteria:
- Ductless heat pumps with an inverter drive
- HSPF of 9.0 or greater
- SEER of 14.5 or greater
- 2.5 tons of capacity or less
- Commercial space of 10,000 square feet or less
- Commercial space with electric resistance heat
Participation in the pilot is limited and all sites must be pre-qualified for participation. Restaurants and server rooms are excluded from this offer. Sites may be contacted by a third-party engaged by Energy Trust to install monitoring equipment. Participation in this pilot indicates a willingness to participate in pilot evaluation activities. Additional requirements apply.
