What is a common sign of a malfunctioning boiler?

A common sign of a malfunctioning boiler is unusual noises or pressure drops. When a boiler operates normally, it should run quietly and maintain a stable pressure within its system. If you start to hear knocking, banging, whistling, or any other unusual sounds, it could indicate problems such as sediment buildup, a failing pump, or issues with valves. Additionally, pressure drops can signal leaks, blockages, or other serious malfunctions that could compromise the boiler's efficiency and safety. Recognizing these signs is crucial for timely maintenance and repairs, ensuring that the boiler operates safely and efficiently.

On the other hand, a consistent green light indicator typically denotes that the boiler is functioning correctly. Increased steam output might suggest operational efficiency under specific conditions but isn't necessarily a sign of malfunction unless accompanied by other symptoms. Regular temperature readings should also align with the expected performance parameters of the boiler, so they don't inherently indicate a fault unless they deviate from normal operating conditions.
