Furnace vs Boiler in Coos County, New Hampshire
When a furnace makes sense
If your home already has ductwork, a furnace is the straightforward choice. It heats the air directly and sends it through the ducts you already have. You're heating for about 10 months a year here, and nights averaging 8°F through the winter don't ask anything unusual of a furnace sized for this county.
When a boiler makes sense
If your home heats through radiators or pipes in the floor, a boiler fits what's already there. It runs about 5% cheaper than a furnace at New Hampshire prices, and that difference adds up over a heating season that runs close to 10 months. A boiler heats water rather than air, so it holds the same steady output on an 8°F night as any other.
