Protecting your hydronic heating system from damage caused by low-water conditions is achieved with the Lochinvar 100208665. Designed as a safety-critical control, this 100208665 low water cutoff automatically monitors water levels to prevent dry-firing, effectively safeguarding the heat exchanger from thermal stress.
This component utilizes a high-sensitivity sensor and an integrated pressure-based mechanism. When the system water level drops below the designated safe operating threshold, the unit interrupts the boiler circuit; once the water supply is restored to the correct operating pressure, the device triggers an automatic reset to resume normal heating cycles.
Key System Performance Baselines:
- Automatic Reset: Self-restoring functionality ensures continuous operation after water levels normalize.
- Thermal Protection: Prevents dry-firing and potential heat exchanger damage due to system leaks or low fill pressure.
- OEM Compatibility: Engineered specifically for compatibility with Lochinvar and A.O. Smith boiler configurations.
⚠️ Application Profile: Primarily utilized in commercial and residential hydronic heating systems, boilers requiring automated low-water level monitoring, and integrated safety circuits for space heating and domestic hot water generation.
