Boiler Water Treatment Part 2 Internal Treatment

Generally it is desirable to have a slightly high pH for boiler feed water. Ideally the feed water should be in the range of pH 8.5 9.5. This ensures that free carbon dioxide within the system becomes fixed. If copper fed lines or heaters are used, restrict the feed water pH to a maximum of 9.2.
