What to do if your boiler loses pressure - British Gas
Alkalinity. The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover. A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided. Values higher than this can lead to embrittlement of the steel. Phosphates. Phosphates are used to react with calcium hardness in the boiler water.
The position set when the boiler was installed is sometimes shown by a red indicator needle. On most digital gauges, youll see a flashing pressure reading, if theres a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, its possible that
Boiler Making Noise? Heres What To Do
Consequently, a low boiler alkalinity risks increasing corrosion and also allowing hardness salts to precipitate. The low alkalinity can be increased by the addition of an alkaline salt such as sodium hydroxide. Steam boiler high boiler alkalinity. High boiler alkalinity increases the pH and therefore can contribute towards foaming in the boiler.

The pressure for hot water boilers will vary from the boiler system to the boiler system. Most boilers operate with a pressure of 12 PSI. Again, that pressure will differ from one boiler to boiler. Additionally, within the loop, the pressures will vary. As noted above, the expansion tank has a lot to do with the proper pressure
Testing Alkalinity In Boiler Water. Alkalinity is a key control parameter for boilers (outside of the prescribed operating range, it can lead to corrosion, caustic metal embrittlement, and carryover) and cooling water systems (where it has a significant effect on
