Furnaces & Boilers

Heating with propane furnaces, boilers, and space heaters can improve the efficiency, performance and comfort of homes and buildings.

Propane provides more versatility, affordability, and comfort than any other heating choice — it's that simple. Propane heating systems can be configured as central or zone, forced air or radiant. Best of all, propane systems can help buildings and homeowner slash energy costs and greenhouse gas emissions — up to 68 percent, in fact. Here are a few considerations for your project.

Propane Furnaces. Propane furnaces offer great flexibility in both the type and capacity of the equipment, which makes them a good fit for many different types of homes and buildings. High efficiency propane furnaces — generally those with efficiency levels above 90 percent AFUE — capture additional heat from the combustion gasses and use this to increase the heat transfer of the furnace for greater efficiency. Many high efficiency propane furnaces are two-stage or variable speed units, so the furnace heats the home or building steadily and comfortably. And the heated air leaving the furnace is significantly warmer than temperatures offered by electric heat pumps.

Propane Boilers. Propane boilers can serve a home or building’s space heating and hot water needs with high efficiency levels, reliable systems, and versatile designs. They can be categorized as either condensing or non-condensing types, with condensing units having higher efficiency ratings. In space heating applications, these boilers can work in conjunction with a number of heating delivery systems, including hydronic baseboard systems, in-floor hydronic systems, or even forced-air systems where the hot water from the boiler (instead of a furnace) acts as the heat source.

Radiant Floor Heating. A propane water heater or boiler heats water that is pumped through a floor tubing system. By delivering more-even heat, and more heat closer to the floor, these systems can be far more energy efficient than a conventional furnace-and-duct system.

Hybrid Heating. A hybrid heating system is the combination of an air source heat pump (ASHP) or ground source heat pump (GSHP) with a propane or natural gas furnace. Also known as dual-fuel systems, they improve ASHP and GSHP performance by using a propane furnace — typically a high-efficiency unit — in colder, outdoor temperatures, rather than the heat pump's inefficient electric resistance secondary heat.

Space Heaters. Propane space heaters can be freestanding or wall-mounted, can include thermostats and blowers, and typically work even in an electrical outage. They also produce fewer greenhouse gases than space heaters using fuel oil.

Many of these propane appliances are available in Energy Star-qualified models — more than electric appliances in many categories.
