Businesses can save money, increase equipment reliability, and create more comfortable and productive workplaces by making energy-efficient choices when installing, renovating, or replacing heating equipment. Incentives are currently available for:
- Central heating systems (including high-efficiency boilers and furnaces);
- Supplemental or space heating systems (including heat pumps); and
- Controls (including programmable thermostats).
Systems can be fueled by natural gas, oil, and propane and can include ductless heat pumps and variable refrigerant flow systems.

Central Heating Systems
Commercial Boilers and Furnaces
Many businesses are heated with either a boiler or furnace. Energy-efficient models are available for all heating fuels. If you’re thinking about replacing your system, consider a new high-efficiency boiler or furnace. Click here for a full list of incentivized boilers and furnaces.
Some high-efficiency models are already discounted at participating Maine distributors for installation at Maine businesses — with no contractor paperwork required. Click here for more information.
Biomass Boilers and Furnaces
Biomass boilers and furnaces are heating systems that are powered by local, renewable fuels. These systems burn pellets or cordwood and distribute heat through a heating distribution system. Click for more information. Click here for more information.
Supplemental or Space Heating Systems
Businesses may be able to offset the load of their primary heating system or meet additional heating needs with a high-efficiency supplemental heating system.
High-Performance Heat Pumps
High-performance heat pumps can be used as a heating system. These heat pumps can be installed in areas of your business that have temperature control issues often time because of heat distribution challenges. Units must meet the minimum HSPF (Heating Season Performance Factor) requirements in order to qualify for incentives from Efficiency Maine. Learn more about available incentives here.

Variable-Frequency Drive (VFD) Systems
Variable-frequency drives are retrofit systems used to help heat buildings in a more efficiency manner. A VFD system controls an electric motor through changes in frequency and voltage, allowing the heating systems in a building to run more efficiently.

Forced hot water (“hydronic”) heating systems use circulator pumps to move heated water from boilers to radiators and back. These pumps run whenever a thermostat calls for heat.
ECM Circulator Pumps
Traditional circulator pumps run at one fixed speed and use some electricity to magnetize their rotor. Electronically commutated motor (ECM) circulator pumps can modulate their speed and use permanent magnet motors that don’t require any electricity to have magnetic properties. ECM circulator pumps provide a number of advantages. Learn more about available incentives here. Click here to learn more about circulator pumps.
Businesses can improve heating system efficiency by adding controls to existing systems. Efficiency Maine incentivizes burner controls, boiler economizers, boiler resets, oxygen-trim controls, programmable thermostats, and more. Click here to learn more about incentives for heating controls.
