Laars Heating Systems R2008400 Flow Switch
The Laars Heating Systems R2008400 Flow Switch is a critical safety and operational component designed for high-performance hydronic systems. This replacement flow switch regulates fluid movement in demanding environments, ensuring that the burner circuit only energizes when sufficient flow is detected. As a veteran-grade Laars boiler part, the R2008400 features a durable paddle-style mechanism compatible with various pipe diameters and is a direct replacement for the obsolete E0013100 model. It is engineered to withstand high-temperature and high-pressure conditions typically found in industrial and commercial HVAC flow control applications.
This genuine OEM flow switch is UL-listed and CSA-certified, providing reliable pump protection and system monitoring. It is a vital component for the Laars Rheos (NTH, RHCH, RHCV, RHHH, RHHV) and NeoTherm (500-850) series. By precisely sensing water velocity, this hydronic flow sensor prevents low-flow conditions that could lead to heat exchanger damage or localized boiling. Contractors should verify the paddle length and electrical contact orientation (naturally open or closed) during installation to ensure seamless integration with existing control logic.
Key Benefits
- Direct OEM Replacement: Seamlessly replaces the obsolete Laars E0013100, maintaining original factory specifications.
- Broad Compatibility: Engineered for Laars Rheos and NeoTherm series boilers and volume water heaters.
- Industrial-Grade Build: Constructed to handle the thermal stresses of high-output hydronic loops without signal drift.
- Safety Compliance: UL-listed and CSA-certified to meet strict safety standards for boiler flow monitoring.
- Versatile Application: Includes varying paddle lengths to accommodate different plumbing configurations and flow rate requirements.
Common Questions
How do I troubleshoot a suspected flow switch failure?
If your boiler is stuck in standby mode despite the pump running, check for continuity across the terminals. A common sign of failure is water leaking into the electrical connection box due to a degraded paddle seal, or internal corrosion preventing the paddle from pivoting.
What is the typical activation flow rate for the R2008400?
Most Laars paddle-style switches are calibrated to activate at approximately 0.5 GPM, though specific model configurations and paddle trims may influence the exact trigger point. Always reference your specific boiler’s service manual for required minimum flow rates.
Can I use this switch for both indoor and outdoor units?
Yes, the R2008400 is designed for use in both indoor and outdoor Laars models. For installations where temperatures drop below 15°F, ensure the rest of your system is protected by the appropriate valve heater kits as per manufacturer guidelines.
