What should the pH level of boiler water be?

The appropriate pH level for boiler water is crucial because it influences the overall operation and longevity of the boiler system. A pH level of around 11 is typically considered ideal for boiler water. This slightly alkaline environment helps to prevent corrosion and scaling within the boiler system.

When the water is too acidic (low pH), it can cause corrosion of the metal components of the boiler, leading to potential leaks and failures. Conversely, if the pH is too high (significantly above 11), it may contribute to the formation of deposits, which can also interfere with proper heat transfer and boiler efficiency. Maintaining a pH around 11 strikes a balance that minimizes the risks associated with both acidity and alkalinity, thereby ensuring the effective functioning of the boiler and extending its lifespan.
