Model 623900155 is a 6-foot hydronic baseboard heating sub-assembly from Weil-McLain, engineered for closed-loop hot water heating systems. This assembly is designed for high-efficiency heat transfer using a combination of copper tubing and mechanically bonded aluminum fins, optimized for low-profile perimeter heating installations in residential and light commercial applications.
The sub-assembly integrates into a compatible enclosure system and supports both new system builds and retrofit applications. Constructed with materials selected for thermal performance and corrosion resistance, it provides consistent output over its operating lifespan. It is particularly suited for systems with moderate-to-high heating demands and is frequently specified in multi-zone radiant panel configurations.
Professional installation is recommended to ensure compliance with plumbing and mechanical codes. Horizontal alignment and bracket support are required to maintain tubing pitch and promote air elimination. Field connections should be brazed or soldered per local code. Thermal expansion and contraction must be accounted for in system design.
When integrating with boiler-driven systems, confirm that output ratings align with calculated heat load per zone. Ensure flow rates and head loss are properly addressed during system balancing. This product is compatible with thermostatic zoning and can be incorporated into systems using either manual or electronic zone valves.
