Description
Laars Heating Systems R2008400 Flow Switch
The Laars Heating Systems R2008400 Flow Switch is an OEM replacement component engineered to safeguard your Laars boiler or water heater by verifying adequate water flow before allowing the burner to fire. By confirming proper circulation is present, the flow switch helps prevent dry-firing, overheating, and premature heat exchanger damage — protecting your system investment and extending equipment life.
Key Features
- OEM Laars Heating Systems replacement flow switch
- Designed to confirm water flow prior to burner ignition
- Helps prevent dry-fire conditions and heat exchanger damage

Why Flow Switches Matter
Flow switches are a critical safety component in hydronic heating systems. When water flow drops below the required threshold — due to a closed valve, pump failure, or system blockage — the flow switch interrupts the control circuit, preventing the burner from firing into a dry or low-flow heat exchanger. This simple but essential device protects against costly repairs and system downtime.
