Furnace vs Boiler in Multnomah County, Oregon
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It uses that ductwork to move heat through the house, and with nine months of heating ahead of you and nights averaging 34°F, you want a system that's already set up to work. No ducts to add, just a furnace tied into what's there.
When a boiler makes sense
If your home is heated by radiators or in-floor pipes instead of ducts, a boiler is what fits, since it heats through that piping rather than pushing air. It also runs about 5% cheaper here than a furnace, which adds up over nine months of heating a year. If you don't have ducts and don't want to add them, this is the machine built for that.
