What is the main function of a low water cut-off on a hot water boiler?

To maintain the pressure in the boiler
To prevent low water conditions
To regulate the temperature of the steam
To shut down the burner in case of excess water

The correct answer is: To prevent low water conditions

The primary function of a low water cut-off on a hot water boiler is to prevent low water conditions. A low water cut-off device is essential for safety because it detects the water level within the boiler and shuts down the burner if the water level drops below a specified point. This action prevents the boiler from operating in a low water condition, which can lead to overheating, damage to the boiler components, and potential failure or explosive conditions. By ensuring that the boiler operates only when there is sufficient water present, the low water cut-off effectively protects the system and maintains safe operating conditions. Other options may describe different functions related to boiler operation but do not directly address the critical safety role of the low water cut-off.
