This complete baseboard unit ships in white and is built for situations where wall space is limited but heating output cannot be compromised. The Senior line is classified as a Hi-Output baseboard, making it appropriate for larger rooms and spaces that require greater heat delivery from a low-profile enclosure. Boxed and serrated aluminum fins increase the radiating surface area and direct convection airflow for improved heat transfer. Licensed HVAC technicians and heating contractors install this unit as part of a hydronic loop system.\u003c\/p\u003e\n\u003cp\u003eThe 55wsr-5a-3 is suited for large residential rooms, open floor plans, and light commercial spaces served by a hot-water boiler system. The 5-foot length accommodates standard under-window and perimeter-wall installation locations. The enclosure height is low enough to fit beneath most window sill heights, making it a practical choice for renovation and new-construction hydronic systems. Splice plates are included with this 5-foot length to simplify joining sections when extending runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHi-Output Senior series design rated for large residential and light commercial hydronic applications\u003c\/li\u003e\n  \u003cli\u003eBoxed and serrated aluminum fins increase radiating surface area and direct convection flow\u003c\/li\u003e\n  \u003cli\u003eExclusive Silent Glide Shoe allows the heating element to expand and contract without noise\u003c\/li\u003e\n  \u003cli\u003eHeavy-gauge brackets snap into place without sheet metal screws\u003c\/li\u003e\n  \u003cli\u003eTelescoping fill-in sections eliminate field cutting and material waste\u003c\/li\u003e\n  \u003cli\u003eFlared tube at one end removes the need for additional couplings at that connection point\u003c\/li\u003e\n  \u003cli\u003eSplice plates included with 5-foot length for multi-section runs\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 residential and light commercial hydronic hot-water baseboard heating systems with 3\/4-inch element connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or heating contractor familiar with hydronic piping systems. Shut down the boiler and depressurize the affected zone before disconnecting or connecting any baseboard element. Follow local mechanical codes and manufacturer sequence-of-installation instructions when joining multiple sections with splice plates. Verify that wall blocking and flooring clearances meet local building code requirements before securing brackets.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Senior Hi-Output\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFin Type\u003c\/strong\u003e: Boxed and serrated aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSplice Plates Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBracket Mounting\u003c\/strong\u003e: Heavy-gauge snap-in, no sheet metal screws required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STERLING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 55wsr-5a-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STERLING","offers":[{"title":"Default Title","offer_id":51467357978930,"sku":"55WSR-5A-3","price":147.2,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946484.jpg?v=1783901949","url":"https:\/\/voomisupply.com\/products\/sterling-55wsr-5a-3-hydronic-baseboard-5-ft-senior-white","provider":"Voomi Supply","version":"1.0","type":"link"}
