A fireplace and chimney assembly is provided which includes a two wall chimney construction and a termination shield for reducing the amount of cold air which can radiate into a living area. The termination shield encompasses the base of the chimney construction while providing sufficient open area for cooling air to be drawn into the annular space within the two wall chimney construction. A false ceiling is installed above the shield. A firestop is provided therein for receiving the top end of the shield. The assembly prevents cold air from dropping into the chase cavity around the fireplace when the fireplace is not in use.

A heat exchanger having an ambient air entrant opening and a heated air discharge opening which is adapted for use with, or is provided as an integral assembly for a fireplace is disclosed. The heat exchanger is in the form of a duct and includes a primary heat transfer surface for mounting in surrounding relation with the combustion chamber of the fireplace and at least one secondary heat transfer surface mounted in the duct so that the heat is transferred from the primary heat transfer surface by direct radiation to the at least one secondary heat transfer surface and from the at least one secondary heat transfer surface to the wall surface of the duct opposite the primary heat transfer surface whereby the heat transfer capacity of the heat exchanger is increased in direct proportion to the surface areas of the primary and the at least one secondary heat transfer surfaces.
