Monitoring boiler water chemistry regularly is essential primarily to prevent corrosion and scaling within the system. Proper water chemistry helps to maintain the integrity of the boiler and its components. Corrosion occurs when the metal surfaces come into contact with corrosive substances in the water, which can lead to leaks, structural failures, and reduced lifespan of the boiler. Scaling, on the other hand, is typically caused by hard water that contains minerals like calcium and magnesium. When the water is heated, these minerals can precipitate out and form solid deposits. If allowed to accumulate, scale can insulate heating surfaces, reduce efficiency, and potentially cause overheating and damage.

By regularly monitoring and adjusting the water chemistry, operators can ensure that the pH levels are correct and that the levels of dissolved solids, oxygen, and other corrosive agents are within acceptable limits. This proactive approach significantly minimizes the risk of costly repairs and downtime due to boiler failure, leading to a safer and more efficient operation.
