What is an indicator of proper boiler operation?

Consistent pressure readings are a key indicator of proper boiler operation because they signify that the boiler is functioning within its designed parameters. When a boiler maintains stable pressure, it indicates that the system is effectively regulating steam or water for heating without significant leaks or faults. Stable pressure conditions promote the efficient transfer of heat and ensure safe operation, as fluctuations can lead to stress on components, increased wear, or safety hazards. Thus, a boiler achieving and maintaining consistent pressure supports overall efficiency and optimal performance, making it a vital aspect of proper operation.
