Ideally it should be between 8.5 and 9.5. If the pH is lower than that, the boiler water will start eating the pipes and attacks the boiler equipments as well. If it's higher than that, the boiler water won't corrode metal, but it may begin to foam. Also too high pH may result in attack on copper containing parts.

May 04, 2016 · pH – Boiler and Condensate. pH is a measure of the acidity or basicity (alkalinity) of water on a scale running from 0 to 14. The neutral point on this scale is pH 7; values below 7 indicate increasing acidity and those from 7 to 14 indicate increasing basicity. Since the pH scale is logarithmic, each change in pH value by a whole unit
