Answer: Do I Need a Low Water Alarm on My Boiler?

A low water alarm (low water cutoff) is required on steam boilers and recommended on hot water boilers. It shuts down the boiler if water level drops below safe minimums. For residential hot water boilers, low water alarms are less common because the system is closed and pressurized. However, they provide valuable protection against dry-firing damage.
