Furnace vs Boiler in Woodbury County, Iowa
When a furnace makes sense
A furnace makes sense if your house already has ductwork in place, since that is what it needs to run. Most homes in this region heat this way, and with winter nights averaging 14°F from December through February, it will bring the house up to temperature quickly. The same ducts can carry central air if you add cooling later.
When a boiler makes sense
A boiler makes sense if your home is already set up with radiators or in-floor pipes instead of ducts. It runs about 5% cheaper to operate here than a furnace, which adds up over the 8 months a year you're heating. The heat is steady and even, without the bursts of air a furnace puts out.
