ABSTRACT:
This circulating fireplace system preferably includes a fireplace comprising three metallic shells having air spaces between them for cooling purposes, together with a thermosiphonic chimney having three concentric tubular members coupled to the respective shells of the fireplace. Means is provided for impelling cooling air downward between the outer tubular members of the thermosiphonic chimney in addition to the air which would flow there by virtue of the thermosiphonic effect. Part of the air impelled down the chimney is used to cool the fireplace and then flows upward through the chimney to supplement the flue-cooling effect of the thermosiphonic air flow. The remainder of the impelled air is released from the fireplace either directly to the room or through ductwork in order to heat the room where the fireplace is located, or other rooms of the same structure.
