Furnace vs Boiler in Spokane County, Washington
When a furnace makes sense
If your home 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 to get heat into every room. With ten months of heating ahead of you each year, that simplicity matters more than a small difference in running cost.
When a boiler makes sense
If your home heats through radiators or pipes in the floor instead of ducts, a boiler is the machine built for that. It runs about 5% cheaper to operate here than a furnace, which adds up over ten months of heating a year and nights that average 24°F. It will not do anything for you in the summer, since a boiler only heats, but neither does a furnace.
