Your home likely already has either a furnace or a boiler as the heating system. It is important to know the difference. A furnace heats air—usually using electricity, fuel oil, or natural gas. That heated air is then moved throughout your home via ducts.Boilers heat water or create steam. No matter if heated water or steam is used, it is transported throughout your home using pipes. Boilers also use different fuel types to heat the water, including oil, propane, and natural gas. Typically people do not go from a boiler to a furnace or vice versa, as that would require the complete removal of your current heating system.
