This 4-foot unit accepts 3\/4 inch tube and ships in a complete white finish, making it ready for straightforward installation against perimeter walls. The Senior line is the hi-output variant in the Sterling lineup, delivering higher heat output from a low-profile enclosure suited for spaces where wall height is limited. Boxed and serrated aluminum fins increase the radiating surface area and direct convection airflow for efficient heat transfer. The unit is installed by plumbers and HVAC technicians as part of a hot water hydronic heating system.\u003c\/p\u003e\n\u003cp\u003eThe 55WSR-4A-3 is appropriate for large residential spaces and light commercial environments where standard-output baseboard cannot meet the heating load. The low-height enclosure fits along perimeter walls without interfering with furniture placement or window trim. The classic white painted finish is intended to blend with standard interior trim. Finger-tip temperature control is managed through a damper integrated into the enclosure, allowing occupants to adjust output without tools. This unit is packaged as a complete assembly in the 4-foot length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSenior Hi-Output design suited for large residential and light commercial hydronic systems\u003c\/li\u003e\n  \u003cli\u003eExclusive Silent Glide Shoe allows the heating element to expand and contract without noise\u003c\/li\u003e\n  \u003cli\u003eBoxed and serrated aluminum fins increase radiating surface and promote convection airflow\u003c\/li\u003e\n  \u003cli\u003eHeavy gauge brackets snap into place without sheet metal screws\u003c\/li\u003e\n  \u003cli\u003eFlared tube at one end eliminates the need for couplings at that connection point\u003c\/li\u003e\n  \u003cli\u003eTelescoping fill-in sections remove the need for field cutting and reduce waste\u003c\/li\u003e\n  \u003cli\u003eClassic white painted finish complements standard interior wall and trim colors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for 3\/4 inch tube hydronic baseboard heating systems in residential and light commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or HVAC technician familiar with hydronic heating systems. Shut down the boiler and relieve system pressure before making any pipe connections. Verify that the supply water temperature and flow rate are within the system design parameters before startup.
