What is a common cause of overheating in a boiler?

Low water levels in a boiler can lead to overheating because boilers rely on water to absorb and carry away heat generated during operation. When the water level is low, there is insufficient coolant in the system, and the heat from the burners cannot be effectively absorbed. This results in the boiler components, particularly the heating surfaces, reaching temperatures well above their designed limits, which can lead to severe damage or even a catastrophic failure.

In a boiler system, maintaining the appropriate water level is crucial for safe and efficient operation. Automatic water level controls and regular monitoring are typically implemented to prevent low water conditions. If low water levels are not addressed, it can cause the boiler to overheat, potentially resulting in equipment damage and safety hazards.
