The commercial and industrial HVAC boiler systems use this low water cut-off as a standard safety feature to protect boilers from overheating events. The float block system operates reliably without requiring electrical elements. The system provides three main advantages: enhanced safety and decreased maintenance requirements along with longer equipment lifetime because of its water level monitoring capabilities.
