    Water Maintenance Essential to Prevent Boiler Scaling

    When untreated boiler water is heated, this calcium and magnesium will precipitate from the solution to form hard scale on the tube surfaces. In addition to the overheating and eventual failure of the boiler tubes due to scale, efficiency is also decreased in the short-term because of the scale's insulating effect on the heat transfer surfaces.
