Wood burning stove heat exchanger

A wood or coal burning stove comprising:

• walls defining a fire chamber, with a flue disposed in one of said walls;
• a door in one of said walls providing access to said fire chamber;
• means for circulating liquid through said fire chamber to heat the liquid when a fire is burning in said fire chamber, said means comprising:
• a manifold;
• a plurality of fuel supporting pipes physically and fluidly connected to said manifold;
• means for operatively connecting said manifold and pipes to a hydronic system for space heating of areas remote from said stove;
• and
• a heat exchanger comprising a finned pipe including an inlet and an outlet, said heat exchanger mounted so that it is substantially concentric with, and extends a substantial length within, said manifold, said inlet to and outlet from said heat exchanger adapted to be operatively connected to a water tank of a domestic hot water supply.

• and a plurality of fuel supporting pipes physically and fluidly connected to said manifold;
• means for operatively connecting said manifold and pipes to a hydronic system for space heating of areas remote from said stove;
• means for mounting said manifold so that it extends generally horizontally, said means comprising a metal plate defining the wall of said fire chamber opposite said wall having said door therein;
• and
• said means for operatively connecting said manifold to a hydronic system including a container having a cross-sectional area significantly greater than the cross-sectional area of said manifold, said container physically connected to said metal plate and in fluid communication with said manifold.

A wood or coal burning stove comprising:

• a plurality of walls defining a fire chamber, with a flue disposed in one of said walls;
• a door in a first wall, of one of said walls, providing access to said fire chamber;
• two of said walls, second and third walls, on opposite sides on said first wall, comprising side walls, said second wall having a slanted bottom portion;
• means for circulating liquid through said fire chamber to heat the liquid when a fire is burning in said fire chamber, said means including:
• a first manifold;
• a second manifold, means for supporting said first and second manifolds so that they are generally horizontally extending, and vertically spaced from each other, said first manifold above said second manifold;
• a plurality of fuel supporting pipes physically and fluidly interconnecting said first and second manifolds;
• a liquid inlet means to said second manifold;
• and a liquid outlet means from said first manifold;
• and
• a fan mounted to said second wall slanted portion, and positioned for effecting forced air circulation from the exterior of said stove to the volume surrounding said fire chamber to support combustion, the air flowing in a path from below said fuel supporting pipes through the volume between said pipes.
