Abstract
An improved fireplace heat exchanger apparatus having one or more generally first hollow members, wherein each first member has an internally disposed second hollow member thereby creating an annular space between the interior surface of the first hollow member and the exterior surface of the second hollow member. Ducting is provided to direct air/gas flow through the heat exchanger in a controlled, counter-flow manner. The interior portion of the second hollow member is configured to accept a flow of a heat transfer medium for transferring heat energy to a desired location while the annular space is configured to accept a flow of hot combustion gasses from the combustion chamber and direct it toward a chimney. A nozzle disc located in the annular passageway proximate the inlet of hot combustion gasses causes the gasses to circulate within the annular passageway to enhance heat transfer to the second hollow member.
