Furnace vs Boiler in Forsyth County, North Carolina
When a furnace makes sense
If your home already has ductwork, a furnace is the straightforward choice, since that's how it delivers heat. Just over half of homes in this region heat with a furnace, and winter nights here only average about 30°F, so it isn't working against extreme cold the way furnaces further north have to.
When a boiler makes sense
A boiler makes sense if your home heats through radiators or pipes in the floor, since that's how it delivers heat rather than through ducts. It runs about 5% cheaper than a furnace at North Carolina gas prices, which can add up over the 7 months a year your home needs heat. Only about 2% of homes in this region use one, so it's worth confirming your house has the radiators or in-floor piping before counting on that saving.
