Bryan Steam has long printed a brochure that has a Boiler Longevitiy Chart showing Watertube at 40 years, Cast Iron at 35 years and Firetube at 25 years. They reference no study or report for these claims. Does anyone know of an ABMA, ASME, ASHRAE or other study on the comparative longevity of these three boiler type?
