Furnace vs Boiler in Chugach Census Area, Alaska
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It heats the air and pushes it through the ducts you already have, with nothing extra to install. With heat needed close to year round here, and nights averaging 23°F in the depths of winter, you want a system that keeps up without surprises, and a furnace running on natural gas does that.
When a boiler makes sense
If your home is set up with radiators or in-floor pipes instead of ducts, a boiler fits without tearing into your walls to add ductwork. Boiler heat costs about 5% less to run than a furnace at Alaska's prices, which adds up over twelve months of heating a year. It won't cool your home in summer, but at 23°F on a winter night, that's not what you're asking it to do anyway.
