Heat Circulating Wood Burning Fireplaces heat air and use panels, spaced out from the firebox, to help with circulation. To actually allow circulation of hot air from the fireplace to the rest of the room, a Heat-Circulating Fireplace has louvers at the top and bottom, along with a fan to move the air. A fireplace that is classified as “Heat Circulating” will have cooler surfaces, decreasing the risk of a burn, and may require less clearance space. If you aren’t sure which type of fireplace will be right for your home, take a look at our Radiant vs. Heat-Circulating information page, Wood Burning Fireplace page, or call us at (877)669-4669 to speak with a knowledgeable FireplacesNow.com sales representative.
