Furnace vs Boiler in Nez Perce 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 same ductwork can carry cooling later if you ever add central air. With nights averaging 26°F from December through February and heat needed about ten months a year, you want a system built for that kind of run time.
When a boiler makes sense
A boiler makes sense if your home heats through radiators or in-floor pipes rather than ducts. It runs about 5% cheaper than a furnace at local gas prices, which adds up over a heating season that stretches close to ten months. It only heats, so it fits a home with no plans to add central air through ducts.
