What is one of the main functions of a low-water cutoff in a boiler system?

To monitor steam pressure
To prevent overheating of the boiler
To ensure adequate fuel supply
To maintain proper water levels

The correct answer is: To maintain proper water levels

One of the main functions of a low-water cutoff in a boiler system is to maintain proper water levels. This device is critical for the safe operation of a boiler, as it detects the water level within the boiler and ensures that it does not drop below a safe threshold. If the water level gets too low, the low-water cutoff will automatically shut off the boiler to prevent the risk of overheating and potentially damaging the boiler. Proper water levels are essential not only for the efficient operation of the boiler but also for safety. If water levels are inadequate, there may not be enough water to absorb the heat generated, which can lead to overheating of the boiler components. By maintaining the correct water levels, the low-water cutoff plays a vital role in safeguarding the boiler system from hazardous conditions.
