What does a low water condition in a boiler result in?

A low water condition in a boiler can lead to overheating because the water serves as a coolant for the boiler’s heating surfaces. When there is insufficient water in the boiler, the heat generated by the burner cannot be effectively absorbed, leading to localized areas becoming excessively hot. This overheating can damage the boiler components, potentially causing metal failure and other serious issues.

The relationship between water levels and temperature management is critical in boiler operation. Adequate water levels ensure proper heat distribution, while low water levels compromise this balance, making overheating a significant risk. Understanding this concept is essential for maintaining boiler safety and efficiency.
