Furnace vs Boiler in Brown County, Wisconsin

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. It ties into the ducts you have and heats the whole house through them, and with 9 months of the year needing heat here, you want that system to be one your contractor already knows well. Most homes in this region are set up this way already.

When a boiler makes sense

If your home heats through radiators or in-floor pipes instead of ducts, a boiler is built for exactly that, and it runs about 5% cheaper here than a furnace. At 14°F on a winter night, that steady radiant heat holds its own. It makes the most sense in a house that was never set up for ductwork in the first place.
