In addition to the requirements for all heat pump projects, the following are requirements for CMLP's whole home heat pump rebate:
- Heat pumps must be new and sized to be capable of being the sole source of heating in the home (i.e. sized to meet 90 - 120% of the total heating load at the outdoor design temperature, per ACCA Manual J Design Conditions, throughout 100% of the conditioned space. Conditioned space is defined as the space designated as living area in the Assessor’s database.). Homes may maintain back up heat from a wood or pellet stove or supplemental heat from existing electric resistance heating, ETS or heat pumps.
- Project must either include the removal or disconnection of the pre-existing heating system, or the homeowner must not use the pre-existing heating system unless there is an emergency or unless the pre-existing heating system is the source of hot water for domestic uses. An emergency is defined as heat pump maintenance down-time or if the heat pump is not able to heat the home during an extreme weather event.
- A customer and their installer must sign the whole home heat pump verification form and submit it with the heat pump rebate application.
- The installer must submit a Manual J heat load calculation with the online post-installation quality assurance (QA) form to Abode Energy Management for heat pump projects. Click for the air-source heat pump QA form or for the ground-source heat pump QA form.
- Because the heat pump system for which the rebate is being sought must be sized to be capable of being the sole source of heat in the home:
- a customer installing more heat pumps to supplement existing heat pumps is eligible for a partial home heat pump rebate, not a whole home heat pump rebate, if the new heat pumps are sized to meet less than 90% of the heating load.
- a heat pump sized for whole home AC but inadequate for whole home heating is eligible for a partial home heat pump rebate but not for a whole home heat pump rebate.
- A customer installing a new heat pump system to replace existing heat pumps is eligible for a whole home heat pump rebate if the new heat pump system is sized to be capable of being the sole source of heating in the home, as defined above.
- Heat pump rebates are available to each condominium owner for a heat pump solely serving his/her living unit, if the living unit has its own service address. Eligibility for whole home or partial home rebates depends on the number of units in the condo complex and when the heat pump project planning began. If heat pump project planning had not begun by January 1, 2023, equipment installed in individual units in residential 5+ unit complexes, including 1-4 unit buildings that are part of larger complexes, are not eligible for whole-home rebates but are eligible for the partial-home rebate amounts of $1,250/ton for air-source heat pumps and $2,000/ton for ground-source heat pumps. Project planning had begun if the condo owner had requested heating/cooling coaching services or if the condo owner's installer had received a heat pump project pre-approval from Abode Energy Management before January 1, 2023. The annual cap per service address and other rebate policies apply.
- A heat pump installed in an outbuilding on a customer’s property is not eligible for a whole home heat pump rebate, even if the heat pump is the sole source of heating in the outbuilding. An outbuilding is shown in the Outbuilding section of a property record in the Town of Concord’s online assessment database. Outbuildings are eligible for a rebate of $1,250/ton of cooling capacity up to $2,500 per outbuilding.
