What is a common consequence of failing to treat water in a boiler system?

• A. Decreased water hardness
• B. Improved heat output
• C. Increased risk of scaling and corrosion
• D. Lower energy costs

Answer: (C)

Failing to treat water in a boiler system can lead to an increased risk of scaling and corrosion. Water that isn’t properly treated may contain impurities such as minerals, oxygen, and other contaminants. When hot water is heated in the boiler, these impurities can precipitate and form scale on the boiler tubes and heat exchangers. This scaling reduces heat transfer efficiency, which can lead to overheating and damage to the boiler components over time.

Additionally, untreated water can also lead to corrosion. The presence of oxygen and other corrosive elements can lead to the deterioration of metal surfaces, causing leaks and even catastrophic failures. Therefore, proper water treatment is crucial to maintain the integrity and efficiency of a boiler system.
