Furnace vs Boiler in Washington County, Wisconsin
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It's what most homes in this region are set up for, and that same ductwork can carry central air later if you ever want it. With winter nights averaging 14°F and heat needed about eight months of the year, you want a system that matches what your house is already built around.
When a boiler makes sense
If your home heats through radiators or in-floor pipes instead of ducts, a boiler is the machine that fits what's already there. It runs about 5% cheaper than a furnace at Wisconsin gas prices, which adds up over an eight-month heating season. It makes the most sense for a house that was never set up for ductwork in the first place.
