Why is maintaining proper water levels in a boiler critical?

Maintaining proper water levels in a boiler is essential primarily to prevent overheating and possible damage to the boiler. Boilers operate based on a specific balance between water and steam. When water levels drop too low, the heating surfaces can become exposed, leading to overheating. This can potentially cause serious damage to the boiler, such as warping or rupturing of the metal components.

In addition to protecting the boiler's structural integrity, proper water levels also ensure that steam production remains efficient, allowing the system to function effectively without undue stress on its components. It assists in regulating temperature and pressure within safe parameters, further contributing to the longevity and operational efficiency of the system.
