The Lennox® Heat Exchanger is a heat exchanger consisting of energy saving tubes that are individually replaceable. Each tube is connected to a water pipe or solvent line, and in areas where multiple heat exchangers are used, the tubes can be piped together using branch kits for easy removal and replacement, and keeping them in place while installed.
