2025 Optional Air Source Heat Pump Pre-Approval Request

Please review CMLP's Heat Pump Rebates for Your Home webpage carefully to ensure that you understand the 2025 rebates and eligibility criteria.

If you have questions about this form, contact CMLP Energy Efficiency & Electrification Coordinator Jan Aceti, at jaceti@concordma.gov or 978-318-3151.

Is natural gas the building's primary heating fuel?*

YesNoNo - the building has gas as a supplemental heating fuel but not as the primary heating fuel

Customers of CMLP who heat their home primarily with natural gas are eligible for Mass Save's air-source heat pump rebates. CMLP does not offer rebates to these customers. Please refer to the Mass Save heat pump rebate webpage here, and assist your customer with applying for the applicable Mass Save rebate. The Mass Save program does not require a pre-install or post-install approval.

Existing heating fuel(s) and system(s) in the zone(s) the heat pumps will be conditioning:*

	Existing heating fuel	Existing heating system type
Existing primary system
Existing secondary system, if present. Otherwise, leave blank.
Other existing system, if present. Otherwise, leave blank.

Is this project a whole-home, partial-home, or outbuilding solution? (i.e. is your customer applying for CMLP's whole-home rebate, partial-home rebate, or outbuilding rebate?)*

Whole home (Heat Pump Only)Partial home (Dual-Fuel/Hybrid)Outbuilding

A Manual J heat load calculation is required for whole home systems. Please upload it here.*

Must include input summary page

Did you complete a Manual J to estimate the heating load?*

Upload of Manual J report*

Include input summary page

If this project uses supplemental electric heat (electric resistance units/baseboards, existing heat pumps and/or ETS) in rooms other than bathrooms, the project is eligible for a whole home rebate only if the supplemental electric heat provides no more than 10% of the home's total heat load.

Auxiliary electric resistance strips built into the heat pump itself or non-electric heating systems are allowed for emergency use but not supplemental heat in whole home heat pump projects. Emergencies are heat pump maintenance/repair downtime or if the heat pump is unable to heat the home during an extreme weather event.

Will supplemental electric heat such as electric resistance units/baseboards, existing heat pumps or ETS be used in any rooms other than bathrooms to meet the home's total heat load?*

YesNo

What type of supplemental electric heat will be used in each room? Enter the name of each room and select all electric heat sources that apply.*

	Name of Room	Existing Heat Pumps	Electric Resistance Units or Baseboards	ETS	Other
Room 1
Room 2
Room 3

Please use either Option 1 or Option 2 (not both) to provide CMLP with information that it can use to determine the percentage of the home's total heat load met by the supplemental electric heat.

OPTION 1: If existing heat pumps are the only source of supplemental electric heat, please enter the outdoor and indoor unit model numbers of the existing heat pumps.

	Outdoor Unit Model #	Indoor Unit Model #1	Indoor Unit Model #2	Indoor Unit Model #3
Existing Heat Pump 1
Existing Heat Pump 2
Existing Heat Pump 3

OPTION 2: If the supplemental electric heat is electric resistance only or a combination of electric resistance, existing heat pumps and/or ETS, provide the information called for in either Option 2.A or Option 2B, but not both.

Option 2.A. A room by room Manual J heat load calculation including all rooms in the home's living area was uploaded in the field above.

Yes

Option 2.B. A block load Manual J heat load calculation including all rooms in the home's living area was uploaded in the field above. A block load Manual J without the rooms heated by supplemental electric heat is uploaded here.

Must include input summary pages.

CMLP requires that all projects obtain an electrical permit and that the Town of Concord’s electrical inspector inspect and approve the installation. Please confirm that you understand this requirement.*

Yes, I understand.

Does this project have sheet metal duct work beyond minor repairs? Examples are installing new ducting, or replacing, changing, or significantly repairing existing ducting.*

CMLP requires that all projects involving sheet metal ducting work that goes beyond minor repairs obtain a sheet metal permit and that the Town of Concord’s inspector inspect and approve the installation. Please confirm that you understand this requirement.*

Yes, I understand.

More information about Town of Concord Building Department permits and inspections can be found in the Quality Assurance Section of CMLP's Heat Pump Rebates for Your Home page.

An energy assessment within the last three years or scheduled within six months after project completion is required by CMLP for projects involving homes built before 2008. A completed Energy Saver Home Loan Program decarbonization plan is an acceptable alternative. Outbuildings are exempted. Please confirm that you and your customer understand this requirement.*

CMLP requires that partial-home systems include integrated controls in most cases. The controls must be on the Mass Save HPQPL. Please confirm that if required, you will install integrated controls that are on the Mass Save HPQPL and list the integrated controls' model number on your Invoice.*

Yes, I will install integrated controls for this project.Integrated controls are not required because the supplemental heating system is electric resistance, existing heat pumps or ETS.Integrated controls will not be installed because there is no other heating system in the zone to integrate with.

If the supplemental heating fuel is oil, CMLP requires that the integrated control swap-over temperature must be 30°F or lower. If the supplemental heating fuel is propane, CMLP requires that the integrated control swap-over temperature must be 15°F or lower.*

The existing fuel is oil and the integrated controls will be staged with a swap-over temperature no higher than 30°F.The existing fuel is propane and the integrated controls will be staged with a swap-over temperature no higher than 15°F.N/A - the existing fuel is neither oil nor propane, or there is no other heating system in the zone to integrate with.

Does the system being installed include auxiliary electric resistance heat incorporated into the heat pump itself?*

At approximately what outdoor temperature will the auxiliary electric heat need to turn on?*

Is the system being installed a dual fuel heat pump?*

A dual-fuel heat pump includes a fossil fuel heat source, integrated controls and a switchover strategy

At approximately what outdoor temperature will the dual fuel heat pump need to switch to fossil fuel backup?*
