A fireplace comprises a firebox which has a flue and front, bottom, top, rear and side panels. An outer casing is spaced from and surrounds the firebox. A combustion air plenum is positioned at a point above the bottom of the firebox and is connected to a conduit that communicates with a source external to the room in which the fireplace is situated for supplying combustion air to the fireplace. The firebox has a combustion air entry port in at least one of side panels of the firebox near the bottom of the firebox for supplying combustion air to the interior of the firebox. The combustion air port communicates with the combustion air plenum through a first passage. The flue passes upwardly through the firebox and is adapted to be connected to a second conduit that is in communication with a source external to the room which the fireplace is situated for exhausting the combustion gasses from the fireplace. A second passage is provided between the outer casing and the firebox for circulation of air to be heated along the firebox.
