Our Cerona wraps arched elegance around robust heat and high efficiency. With your choice of a 36" or 42" viewing area, this is the best efficiency you'll get in a Heat & Glo fireplace. Patented FireBrick® material, crafted with cantilevered corners, looks just like a masonry hearth and provides better radiant heat. And as a whole hearth system, it's got a great selection of mantels, surrounds, fronts and finishes to suit any interior design. High heat, high efficiency and high style.
