  • Guidance on Safe Operation of Hot Water Boilers

    Replacing Your Furnace or Boiler. Although older furnace and boiler systems had efficiencies in the range of 56% to 70%, modern conventional heating systems can achieve efficiencies as high as 98.5%, converting nearly all the fuel to useful heat for your home.Learn More

  • Boiler Water Treatment Guidelines; Columbia Boiler Co

    Use proper water treatment to prevent the buildup of scale on the boiler. After scale has built up on the walls of the boiler it is almost impossible to remove it from the boiler. The introduction of acids in the pressure vessel is thoroughly discouraged, since virtually any solution that will chemically attack the scale will also attack the boiler metal.Learn More

  • Boiler Safety

    Carryover occurs when a high boiler water level causes water particles to be carried into steam lines. 7- is a condition resulting from water pumped that becomes too hot and turns to steam. The feedwater pump is designed to pump liquids, but does not work with air or steam. Standards for eye protection are specified in ANSI Z87.1-1989,Learn More
