A heating stove has a fire box composed of first and second pluralities of parallel aligned connected vertically oriented curved open-ended conduits lower extremities of the conduits of said first and second pluralities being aligned for contacting a common planar surface to support the stove, with the fire box further being formed by generally planar front and back plates, of substantially the same size and shape, with the front plate having an inlet port therethrough and the back plate having an exhaust port therein. The conduit central portions are largely within the stove fire box. A baffle within the fire box promotes three-pass flow of hot air across the conduit surfaces within the fire box. The first and second pluralities of curved conduits are opposed and in interdigitated engagement. Curved strips separate the curved conduits and thus facilitate stove construction with the conduits in interdigitated engagement. A closing mechanism for the stove door operates with caming action to assure that the door, when closed, is tightly fastened so that the hot coals cannot escape. In another embodiment, the fire box is cylindrical, formed by two curved side plates and two generally planar end plates, and the curved conduits pass through the fire box.
