Furnace vs Boiler in Ottawa County, Michigan
When a furnace makes sense
If your house already has ductwork, a furnace uses what's there instead of adding a second way to move heat through the house. Winter nights here average 20°F, and with heat needed about 8 months a year, that ductwork earns its keep most of the year. A furnace heating through ducts you already have is the simpler path.
When a boiler makes sense
If your home heats through radiators or in-floor pipes instead of ducts, a boiler is built for that, and switching to forced air would mean adding ductwork you don't have. Boiler heat runs about 5% cheaper here at current gas prices, which matters over an 8-month heating season. It's the right call for a house already plumbed for it, not a reason to tear out ducts that work.
