    A: The system will overheat, risking immediate damage or catastrophic failure.

    Most modern boilers have a low-water cutoff that automatically shuts off the burner at a specific level, typically around 1-2 inches below the recommended operating line, to prevent damage. Insider Tip: Regularly check the sight glass or water gauge; a monthly check is a standard maintenance practice to prevent low-water incidents.
