Radiant:
A radiant fireplace is also known as a flush face fireplace. The facing (stone, tile, brick, etc.) can cover above and below the fireplace opening to give you a masonry fireplace look.
Circulating:
A heat-circulating fireplace has louvers at the top and bottom so that a fan can be installed in the unit and circulate heat around the firebox and into the room.
High Energy Efficient:
Energy efficient fireplaces are EPA-approved units that offer a balance of elegance and energy efficiency
