Furnace vs Boiler in Rockingham County, New Hampshire
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It heats air and pushes it through the house with a blower, and it only runs on gas here, nothing to add. With eight months of heating ahead of you and winter nights averaging 18°F, that ductwork is already doing the work a furnace needs.
When a boiler makes sense
If your home already has radiators or in-floor pipes, a boiler makes sense to keep using them. It heats water instead of air, and running one costs about 5% less than running a furnace at New Hampshire prices. Over eight months of heating, with nights averaging 18°F, that difference adds up.
