Lochinvar L100275528 Flow Sensor

Product Description

The LOCHINVAR L100275528 is a flow sensor designed for use in hydronic heating and hot water systems. Flow sensors monitor water movement through a system and send a signal to the control board to confirm adequate flow before allowing burner operation. This part is a direct OEM-style replacement intended for installation by licensed plumbers, HVAC technicians, or hydronic heating specialists familiar with LOCHINVAR equipment. Proper flow sensing protects heat exchangers from dry-fire conditions and helps maintain safe system operation.

The L100275528 is suited for residential and light commercial hydronic applications where reliable flow detection is required. It is typically installed in the supply or return piping of a boiler or water heater where flow confirmation is part of the burner control logic. LOCHINVAR equipment used in combination heating and domestic hot water systems commonly relies on this type of sensor to coordinate system sequencing.

Key Features

• OEM LOCHINVAR flow sensor for hydronic heating systems
• Signals the control board to confirm water flow before burner ignition
• Protects heat exchangers by preventing operation without adequate flow
• Direct replacement minimizes setup time during service calls

Compatibility

Designed as an OEM-style replacement flow sensor for LOCHINVAR boilers and water heaters. Consult the equipment service manual or LOCHINVAR technical support to confirm fitment for your specific model before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or hydronic heating specialist. Shut down the boiler or water heater and close the appropriate water supply valves before removing the existing sensor. Follow all applicable local plumbing and mechanical codes during installation. Verify all connections are leak-free and confirm proper sensor signal operation before returning the system to service.
