Furnace vs Boiler in Monroe County, Indiana
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 that same ductwork carries cooling later if you add central air. It also gives you faster recovery on the cold nights here, when temperatures average 24°F from December through February.
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. Running cost is about 5% lower here than a furnace at Indiana prices, which adds up over the 7 months a year you need heat. It won't help with cooling, so it makes the most sense in a home that has no ductwork to begin with.
