Furnace vs Boiler in Black Hawk County, Iowa
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Most homes in this region are set up this way, and a furnace can also carry central air through the same ducts later on. With eight months of heating ahead and nights averaging 13°F, you want equipment that matches what your home is already built for.
When a boiler makes sense
If your home heats through radiators or in-floor pipes instead of ducts, a boiler is the machine built for that. It runs about 5% cheaper to operate here than a furnace, which adds up over eight months of heating season. It will not deliver air conditioning, so if you want central air down the road, you would need a separate system for that.
