Furnace vs Boiler in Dakota County, Minnesota
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It heats through those ducts, so you are not paying to add a delivery system a boiler would need instead. With eight months of heat needed here and nights averaging 10°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 rather than ducts, a boiler is the right fit, and it runs about 5% cheaper here at Minnesota prices. That saving matters over an eight month heating season with nights this cold. It makes less sense to install if your house has ducts already in place, since you would be paying to add radiators or in-floor piping a furnace does not need.
