    Water-tube or fire-tube condensing - Hot Water Boilers

    The feature that makes water-tube boilers so much safer is the volume of water contained. In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn’t melt and create problems. When fire tube boilers run low on water, the metal in the boilers …
