Furnace vs Boiler in Clay County, Missouri
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Those same ducts can carry cooling later, which a boiler never will. Seven months of heating a year, with nights averaging 22°F, calls for equipment built to push hard, and a furnace does that through the vents you already have.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler is the one built for that. It runs about 5% cheaper to operate here than a furnace, which adds up over seven months of cold nights near 22°F. If that kind of system is already in your house, there is little reason to switch it out for ductwork.
