Sterling 55wkp5a-3 Hydronic Baseboard 5 Ft White

Product Description

The STERLING 55wkp5a-3 is a 3/4-inch, 5-foot Kompak hydronic baseboard heater finished in classic white. Designed for residential hot-water heating systems, it delivers convective heat through boxed and serrated aluminum fins that increase radiating surface area and direct airflow for consistent room comfort. The unit features an exclusive Silent Glide Shoe that allows the heating element to expand and contract without noise, making it well-suited for bedrooms, living areas, and any space where quiet operation matters. Licensed HVAC and plumbing professionals are the typical installers for hydronic baseboard systems of this type.

The 55wkp5a-3 is intended for residential hydronic heating applications where wall space is limited and low-profile installation is required. Its slim Kompak silhouette fits beneath windows and along perimeter walls without compromising usable space. At 5 feet in length, splice plates are included to simplify multi-section runs. Heavy-gauge brackets snap into place without sheet metal screws, and telescoping fill-in sections eliminate the need for field cutting, reducing installation time and material waste.

Installation Notes

Installation of hydronic baseboard heaters should be performed by a licensed plumber or HVAC technician familiar with closed-loop hot-water heating systems. Shut down the boiler and relieve system pressure before making any pipe connections or removing existing baseboard sections. Ensure supply and return piping are properly pitched per system design requirements to prevent air binding. All work should comply with applicable local mechanical and plumbing codes.
