What is the primary purpose of a low water cut out in a boiler system?

The primary purpose of a low water cut out in a boiler system is to shut off the burner. This safety device is designed to prevent the boiler from operating when the water level falls below a certain threshold. When the water level drops too low, it poses a significant risk of overheating or damage to the boiler, as the heater elements could become exposed and result in catastrophic failure. By shutting off the burner when low water conditions are detected, the low water cut out helps to ensure safe operation and prevents accidents that can arise from running a boiler without adequate water levels.

This is a crucial safety feature in high-pressure boilers, as maintaining the correct water level is vital for efficient operation and longevity of the system.
