Radiant Wood Burning Fireplaces heat air by utilizing infra-red radiation. The fire heats the fireplace, which then emits infra-red radiation, effectively heating you and your room. Because heat is radiated from the walls of the fireplace, you can create a smooth, flush appearance between your cabinet/surround and the fireplace. Generally, Radiant Wood Burning Fireplaces are very heat efficient because there is an airtight combustion chamber (glass doors must remain shut) and less room to heat inside the fireplace.
