Furnace vs Boiler in Durham County, North Carolina
When a furnace makes sense
If your home already has ductwork, a furnace is the straightforward choice. Just under half of homes in this region heat with a furnace, so ducts are common, though not a given. Seven months of heating a year is a moderate load, and a furnace handles that without trouble.
When a boiler makes sense
If your home heats through radiators or pipes in the floor instead of ducts, a boiler is the machine that matches it. Boiler heat runs about 5% cheaper here than a furnace, which adds up over seven months of use. It suits a house built around that kind of heat, not one that would need radiators or in-floor pipes installed to use it.
