Heating Solutions

High-Efficiency 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 a list of participating distributors.

Variable Refrigerant Flow Systems

Variable refrigerant flow systems can simultaneously heat and cool different parts of the building. These systems can be very efficient because they can take waste heat captured in one part of the building (e.g., a server room, or the face of the building exposed to the sun) and deliver it to spaces requiring heat. Because they rely on a different distribution network than is present in most existing buildings, variable refrigerant flow systems are most often installed in new buildings or as part of large renovation projects.

Ductless Mini-Split Heat Pumps

Mini-split heat pump units are highly efficient systems that can save energy and reduce heating and cooling costs. 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.

Infrared heaters

Infrared heaters warm spaces by providing radiant heat similar to the sun’s rays. They can maintain ambient temperatures with minimal heat loss even when large volumes of cold air are introduced. There heats can be a good solution for maintenance garages, firehouses, loading docks, and warehouses. Look for low-intensity systems in order to qualify for Efficiency Maine incentives.

Warm-air heaters

Warm-air heaters are generally used where heat distribution is localized to a single specific area. Warm-air heaters work like large furnace systems but without the duct work. They are most frequently installed overhead in warehouses and garages. High-efficiency, warm-air heaters fueled by natural gas or propane are eligible for incentives. Look for systems with a thermal efficiency of 93% or higher. Click here for more information.
