Does anyone have experience with the newer double walled Brad White combi cores? I'm considering replacing one of the old ones (with the single wall heat exchanger). I'd rather go for something entirely different but I'm somewhat locked into a particular space, flue vent and piping design.

    How are the new double walled coils constructed?

    Early attempts had a steel coil inside a steel coil. Glass outer coating. Condensation between the two steel surfaces caused them to rust thru from the inside, out.
