Sterling 55wkp4a-3 Hydronic Baseboard 4 Ft White

Product Description

The STERLING 55wkp4a-3 is a complete 4-foot Kompak hydronic baseboard heater finished in classic white. It is designed for low-height installation where wall space is limited, making it a practical fit for residential rooms with restricted clearance beneath windows or along short wall runs. The unit uses hot water from a hydronic heating system to deliver convective heat through boxed and serrated aluminum fins that increase radiating surface area and direct airflow upward into the space. A fingertip temperature control damper allows simple output adjustment without tools. Licensed HVAC or plumbing technicians familiar with hydronic systems are the typical installers.

The 55wkp4a-3 is suited for residential hydronic heating applications where a slim, low-profile enclosure is required. The Kompak line is designed for standard residential spaces where ceiling height, baseboard depth, or aesthetic requirements call for a compact unit. The white painted finish is intended to complement standard interior trim and wall colors. The unit ships as a complete baseboard assembly in a 4-foot length, ready for integration into an existing or new hydronic loop.

Key Features

• Exclusive Silent Glide Shoe allows the heating element to expand and contract without noise during heating cycles
• Boxed and serrated aluminum fins increase radiating surface area and improve convection output
• Heavy gauge brackets snap into place without sheet metal screws, reducing installation time
• Telescoping fill-in sections eliminate field cutting and reduce material waste
• Flared tube at one end removes the need for couplings at that connection point
• Radius-formed end covers and smooth enclosure lines provide a finished appearance that blends with standard interior trim

Compatibility

Designed as an OEM-style replacement or new-installation component for residential hydronic baseboard heating systems using hot water distribution.

Installation Notes

Installation should be performed by a licensed plumber or hydronic heating technician. Shut down the boiler and depressurize and drain the affected loop before making any pipe connections. Follow local plumbing codes and the International Plumbing Code (IPC) for hydronic system work. Do not fire the boiler until all connections are pressure-tested and the system is fully purged of air.
