Furnace vs Boiler in Marion County, Oregon
When a furnace makes sense
If your house already has ducts, a furnace is the straightforward choice. It heats air and a blower pushes it through the house, and with heat needed about 10 months a year here, you want a system that matches what's already in the walls. Just over half the homes in this region are set up this way, so there's a good chance yours is too.
When a boiler makes sense
A boiler makes sense if your home heats through radiators or in-floor pipes instead of ducts. It runs about 5% cheaper than a furnace here, and with heat needed most of the year and winter nights averaging 33°F, that lower cost adds up. It only works if those radiators or floor pipes are already in place, since a boiler has no way to move warm air through ductwork.
