Boiler vs. Furnace: What’s the Difference?

Both boilers and furnaces burn fuel to help heat your home, but they do so quite differently. Furnaces - also called forced air furnaces - directly heat the air, which is then pushed throughout your home. Boilers heat water, which is sent as steam through a radiator system.
