Disclosed is a heat exchanger having an economizer configured as a ring of tubes in a periphery of the heat exchanger. The heat exchanger includes a cylindrical flue collector and a manifold at either end of the cylindrical flue collector. The manifold has a plurality of chambers. The manifold can be made of steel or plastic and governs fluid flow rate and direction within a ring of tubes. At least two rings of heat exchanging tubes, an outer ring and an inner ring, are within the cylindrical flue collector. The rings of tubes are concentric with respect to each other.
