Fireplace insert
This patent describes a prefabricated fireplace apparatus for heating a room, comprising a combustion chamber defined and enclosed by heat conducting side walls, a back wall, a floor and top. The top has an opening to communicate with a flue to exhaust products of combustion in the chamber. The combustion chamber has a front access opening and doors mounted thereon to cover the opening so that when the doors are closed air will not be admitted to the chamber through the opening; an outer wall circumscribing the combustion chamber walls, floor and top to define therebetween an air heating chamber. The air heating chamber is provided with interior walls extending between the air heating chamber walls to define a continuous air passageway through the air heating chamber over the major portion of the area of the walls, floor and top of the combustion chamber from the floor of the combustion chamber to its top; an outlet at the top of the air heating chamber to permit passage of heated air from the air heating chamber to the room; and an inlet at the bottom of the air heating chamber to permit entry of unheated air to the air heating chamber.
