ABSTRACT:
A fireplace heat system to maximize heat transfer from a fireplace to the surrounding environment of the immediate area outside the fireplace to reduce the heat loss of the fire rising up the fireplace flue and chimney. Maximum heat transfer of the fire in the fireplace is obtained by utilization of thermodynamically short pipes, production of turbulence in the pipes, and pipe length to diameter ratio of less than fifty. The fireplace heat system consists of equal lengths of standard black iron malleable pipe forming U-shaped structures having legs on one side connected together to form U-shaped apparatus. The legs on the connected side of the U-shaped apparatus are positioned above and parallel to the fireplace floor. A forced air blower forces air through an air input manifold which connects the legs of the U-shaped structures. Air is forced through the pipes of the U-shaped apparatus and exits at the top of the opposing set of legs into the surrounding environment of the immediate area of the fireplace. The end pipes of the U-shaped apparatus opposite the end of forced air blower are partially closed to restrict, balance and equalize the air flow through all of the pipes. The components of the fireplace heat system are easily replaceable in the unlikely event of burn through of any of the pipes.
