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 sized to be capable of being the sole source of heating in the home. However, the project may include backup or supplemental heat from non-fossil fuel sources, such as a wood or pellet stove or electric baseboard (resistance) heat, including in spaces that are difficult to serve with air-source heat pumps, like bathrooms or small basement utility rooms.
- 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.
- 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 heat pumps they already had is eligible for a partial home heat pump rebate, but not a whole home heat pump rebate.
- 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 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.
