Furnace vs Boiler in Kenai Peninsula Borough, Alaska
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It ties into what's there, and the same ducts carry cooling later if you ever add central air. With nights averaging 9°F and heat needed nearly year round, you want a system that can keep up, and a furnace pushing warm air through your existing ducts does that without any structural change to the house.
When a boiler makes sense
If your home is already set up with radiators or in-floor pipes instead of ducts, a boiler is the natural fit rather than something to work around. Running cost favors the boiler here too, about 5% less than a furnace at local gas prices, which adds up over a heating need that stretches through the whole year. The heat is steady and even, which matters when winter nights sit near 9°F for months at a stretch.
