Sterling 55wsr-6a-3 Hydronic Baseboard 6 Foot Senior White

Product Description

The STERLING 55wsr-6a-3 is a 6-foot Senior series hydronic baseboard heater designed for high-output heating in residential and light commercial spaces. This complete unit ships in white and is built around a boxed and serrated aluminum fin design that increases radiating surface area while directing and enhancing natural convection. The enclosure features smooth, radius-formed end covers and a sleek profile that keeps a low height footprint, making it a practical choice where wall space is limited. A fingertip temperature control damper provides silent operation, and the exclusive Silent Glide Shoe allows the heating element to expand and contract freely without noise. Licensed plumbers and HVAC technicians handle typical installation.

The Senior series is engineered for large residential applications and light commercial hydronic heating systems where higher heat output is required compared to standard slim-profile baseboards. The 6-foot length includes splice plates for field joining and is packaged ready for installation. The telescoping fill-in sections eliminate the need for field cutting, reducing installation time and material waste. Classic white finish is designed to complement standard interior decor and pairs with matching enclosure components available in the Sterling baseboard lineup.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with hydronic heating systems. Shut off the boiler and allow the system to depressurize and cool before disconnecting or connecting any piping. Follow applicable local plumbing codes and IFGC guidelines when integrating into an existing hydronic loop. Do not operate the unit without confirming all connections are leak-free and the system has been properly bled of air.
