  • Patent number: 4091794
    Abstract: A fireplace heat extractor comprising an air-shield, such as a glass screen, to be mounted across the fireplace opening with manually controlled, limited capacity openings therethrough that admit just enough air into the fireplace to support combustion. Baffle means prevent such air from bypassing the fire. A blower directs air through a horizontal header extending through the air-shield into place, and then through an array of tubular air ducts which extend downwardly and rearwardly from the header to function also as a fire basket. The ducts extend up along the back of the fireplace and then forwardly to open back through the air-shield into the room. Replaceable fill bars are positioned between the fire basket portion of the ducts to improve coal-supporting characteristics.
