ABSTRACT:
A steam-type fireplace heat-extraction apparatus, including an enclosure for utilizing the heat generated in a fireplace, comprising an isobaric or atmospheric, superheated steam system combined with a unique enclosure, said enclosure comprising a fireplace frame having vertical side members and horizontal top and bottom members, with two novel door structures which are hingedly carried by the fireplace frame. Each door structure comprises double panes of tempered glass disposed in spaced, parallel relation, held by a door frame which extends around the peripheral portions of the panes and confines the same. The door frames have special ventilating holes located adjacent the top and bottom members of the fireplace frame, which enable air from the room to be drawn into the space between the panes and then discharged, to not only provide heat to the room but also at the same time hold the temperature of the glass to a lower value. Several arrangements of atmospheric, superheated thermal exchangers-radiators are also disclosed, for use in conjunction with the double glass panes, to provide an exceptionally high heating efficiency with surprising simplicity as well as safety, when used with a conventional fireplace construction.
