Boiler Information

All water contains dissolved minerals and these minerals, if allowed to reach high enough levels in the boiler water, will come out of solutions and form as a hard shell on the hot surfaces of the boiler. This hard shell is called "scale" and is often found on the outside of the fire tubes or the inside of water tubes. Scale insulates the
