• What pressure do most hot water boilers operate at?

    The ideal boiler pressure should be between 1 to 1.5 bars on your pressure gauge when your heating is switched off. Around 2 bars is a normal pressure level when your boiler is active/heating up. Anything below 0.5 is too low and must be replaced. Also to know is, How long should my boiler take to heat water? between 30 and 40 minutes 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
