Furnace vs Boiler in Ketchikan Gateway Borough, Alaska
When a furnace makes sense
A furnace makes sense if your house already has ductwork, and just over half of homes in this region do. With heat needed close to 12 months a year here, that ductwork earns its keep well beyond a short winter. If you ever want central air added later, the ducts are already there for it.
When a boiler makes sense
A boiler is worth a look if your house heats through radiators or in-floor pipes rather than ducts, since that's the only way it delivers heat. It runs about 5% cheaper than a furnace here, and with nights averaging 33°F from December through February and heat needed nearly all year, that difference keeps paying off. It won't move air for cooling, so it fits a house that's never had ducts and isn't planning to add them.
