Furnace vs Boiler in Washington County, Oregon
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It uses those ducts to heat the whole house, and just over half the homes in this region are set up the same way. With nine months of heating ahead of you each year, matching what's already in your walls is worth more than a small edge in running cost.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler fits that setup without any changes. It also runs about 5% cheaper than a furnace at Oregon gas prices, which adds up over nine months of heating and nights that average 34°F. It's the right call for a house built around that kind of heat, not one that would need ducts added just to run a furnace instead.
