Furnace vs Boiler in Richland County, South Carolina
When a furnace makes sense
If your home already has ductwork, a furnace is the straightforward choice. Winters here are mild, with nights averaging 36°F and only about five months of heating needed, so you don't need to pay for the extra it costs to run a boiler to get comfortable air through the house.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler is the right fit, and it costs about 5% less to run here than a furnace. It makes the most sense when that piping is already in place, since it won't move air through a duct system that isn't there.
