Laars Heating Systems RE2074000 Well Kit

The Laars Heating Systems RE2074000 Well Kit is a professional-grade component designed for precision temperature monitoring in hydronic heating and domestic hot water systems. This 1/2" NPT immersion well serves as a robust thermal interface, allowing aquastats or temperature probes to interface with the system fluid without direct exposure. By utilizing high-conductivity materials, this Laars replacement part ensures rapid thermal transfer for accurate high-limit or operating control response times.

When performing a boiler repair or upgrading older hydronic heating controls, selecting the correct immersion well is critical to system integrity. The RE2074000 features a standard 1/2 inch NPT connection, making it compatible with a variety of Laars residential and commercial boilers. Its durable construction is engineered to withstand the thermal stressors and pressure fluctuations common in closed-loop systems. Contractors often specify this temperature sensor well for its reliable fit and finish, preventing leaks at the insertion point while providing a clean dry-well environment for the sensing bulb.

• Optimized Thermal Conductivity: Engineered for rapid heat transfer to ensure your HVAC temperature sensors react quickly to internal water temperature shifts.
• System Protection: Creates a sealed barrier that allows for probe replacement or maintenance without the need to drain or depressurize the entire boiler loop.
• Universal Threading: Standard 1/2" NPT threads provide a secure, leak-free fit for most 1/2" manifold ports and boiler taps.
• Industrial Durability: Resists corrosion and scaling, maintaining long-term accuracy for critical temperature monitoring.

What is the thread size for the RE2074000 immersion well kit?
This kit utilizes a standard 1/2" NPT (National Pipe Thread) male connection, which is the most common size for temperature sensing ports in hydronic boiler applications.

Can this immersion well be used with third-party temperature probes?
Yes, as long as the probe diameter matches the internal diameter of the well. It is designed to house standard-sized sensing bulbs used in various boiler control systems.

Is this part compatible with Laars Series 2 and Lite2 heaters?
Yes, the RE2074000 is a standard replacement part for several Laars models requiring a 1/2" NPT well. Always verify your specific model's parts list for exact compatibility.
