The heat exchanger comprises a lower header fed by a blower drawing in room air and delivering this air to a plurality of C-shaped tubes in the fireplace capable of supporting logs. These tubes deliver the air to an upper header, from which the air is fed downwardly by a central C-shaped tube to a room delivery chamber below the lower header. The delivery chamber is part of a lower support on which a glass or other fireplace screen may be placed. The air is heated during both its upward and downward travel and is delivered at floor level.
