ABSTRACT:
A network of air-heating ducts is inserted between the fire bricks of a stove or fire-place to increase the thermal efficiency of the heating apparatus. Cool air from the room is supplied by an electric fan and a manifold to a first series of U-shaped ducts extending between the fire bricks of the floor and rear wall of the heating apparatus and extending forwardly along the top wall to open within the room at the front of the heating apparatus. When fuel is burning inside the fire-box, hot air exits directly into the room. Another series of air ducts extends from the same manifold between the bricks of the side walls of the heating apparatus and connects with an L-shaped chamber mounted adjacent the rear wall of the apparatus. This chamber feeds hot air to other rooms of the house by an additional electric fan connected across the legs of the L-shaped chamber.
