New York Low Pressure Boiler COF Practice

At what point should a low water cutoff device activate?

1. When water level is at 25%

2. When water level drops too low

3. At the end of the heating cycle

4. When the pressure exceeds maximum

The correct answer is: When water level drops too low

The low water cutoff device is a critical safety feature in low pressure boilers. It is designed to activate when the water level drops too low to ensure that the boiler does not operate without sufficient water. If the water level falls below a certain threshold, the device shuts down the boiler to prevent damage, overheating, and potential boiler explosions. This safety mechanism is particularly important because a lack of water can lead to overheating of the boiler's components, risking severe damage and safety hazards. By responding precisely when the water level falls to an unsafe level, the low water cutoff helps maintain safe operating conditions within the boiler system.
