What happens when a low limit temperature control is set too high in a hot water boiler?

The boiler operates efficiently
The system may overheat
The water remains cold
The boiler shuts down completely

The correct answer is: The system may overheat

When a low limit temperature control is set too high in a hot water boiler, the system may not operate within the intended range, leading to potential overheating. The low limit temperature control is designed to maintain a minimum water temperature to prevent issues such as corrosion or to ensure efficiency in the heating system. If this setting is too high, the boiler may continue to heat the water beyond safe operational limits, resulting in excessive temperature conditions. This can cause various complications, such as damage to boiler components, increased stress on the system, and potential safety hazards like overheating or pressure relief valve activation. Maintaining appropriate temperature settings is crucial for both the safety and efficiency of a hot water boiler system.
