Abstract
A corrosion resistant condensing heat exchanger is formed from a flat sheet of engineering metal with a layer of polypropylene sheet material laminated thereto. Each condensing heat exchanger has a condensing flow passage of serpentine shape formed in the laminated flat sheet of engineering metal such that the polypropylene layer will be exposed to the flue gas/condensate environment to provide corrosion resistance to the metal.
