Furnace vs Boiler in Penobscot County, Maine
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It heats the air directly and pushes it through the ducts you have, with nothing extra to add. With nine months of heating ahead of you and nights averaging 10°F, you want a system that matches what's already in your walls.
When a boiler makes sense
If your home is heated by radiators or in-floor pipes instead of ducts, a boiler is the one that fits without tearing anything open. It runs about 5% cheaper to operate here than a furnace, which adds up over nine months of heating a year. That saving is worth the most in a house built for it already, not one you'd have to convert.
