Furnace vs Boiler in Franklin County, Vermont
When a furnace makes sense
If your house already has ductwork, a furnace makes sense here. It heats the air directly and pushes it through the ducts already in place, nothing new to add. With nine months of heating a year and winter nights averaging 11°F, that's a furnace running hard and often through ducts that are already there.
When a boiler makes sense
If your home is heated by radiators or in-floor pipes rather than ducts, a boiler is built for that. It runs about 5% cheaper to operate than a furnace at Vermont prices, and with nine months of heating a year here, that difference adds up.
