Furnace vs Boiler in Oxford County, Maine
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It ties into what is already there, and it can double as central air later since the same ducts carry cooled air too. With nine months of heating a year and nights averaging 10°F, you want a system that can push hard, and a furnace does that well through a duct system already built for it.
When a boiler makes sense
If your home is heated by radiators or in-floor pipes rather than ductwork, a boiler is the natural fit, since converting to ducts is a much bigger job than staying with the pipes you have. Boiler heat costs about 5% less to run here than a furnace at Maine prices, which adds up over nine months of heating. Radiant heat also holds up well through the coldest nights, when outdoor temperatures average 10°F from December through February.
