Efficiency Maine offers rebates and financing for homeowners installing qualified high-efficiency heating equipment. Click on the links below to find out more about high-efficiency systems, rebates, and how much you might save with an energy upgrade.
Central Heating Systems
If you have high energy costs or a heating system that is older than twenty years old, it may be time to consider upgrading your boiler or furnace to a new system. Find out more about high-efficiency options below:
Biomass Boilers and Furnaces
: Central wood pellet and cord wood boilers and furnaces are high-efficiency systems that use a local, renewable fuel resource. Find out more about biomass heating systems here
(also called ground source heat, ground source heat pumps, or geothermal heat pumps) take advantage of the constant temperature of the ground below the frost line to heat in the winter and cool in the summer. Efficiency Maine offers incentives up to $3,000 for geothermal systems through the Home Energy Savings Program
Supplemental or Space Heating Systems
Offset the load of your primary heating system or meet additional heating needs with a high-efficiency supplemental heating system. Many Maine homeowners use these systems as a primary heating source in the parts of their homes that they use the most.
: Ductless heat pumps (or “mini-split” heat pumps) distribute heat and cooling directly to the spaces where they are installed, rather than through a ducted system. Ductless heat pumps have an outdoor unit connected to an indoor unit via small, copper refrigerant lines. Find out more about how Mainers are saving with this new technology here
Pellet and Wood Stoves
: Advances in stove design have dramatically increased output efficiency and convenience, while reducing particulate emissions, compared to older pellet and wood stoves. High-efficiency and low-particulate wood and pellet stoves can be a renewable and cost-effective way to heat your home. Click here to find out more
