Furnace vs Boiler in Bonner County, Idaho
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 ductwork can also carry cooling later if you ever add central air. With ten months of heating a year and nights averaging 22°F, you want a system that's already matched to your home rather than one that needs new infrastructure.
When a boiler makes sense
A boiler makes sense if your home is already plumbed for radiators or in-floor heat, or if you'd rather not deal with ducts at all. It runs about 5% cheaper than a furnace here, which adds up over a heating season that stretches ten months. Heat from radiators or floor pipes tends to feel steadier through those long 22°F nights, since it doesn't cycle on and off the way forced air does.
