Sterling sus-3 Suntemp 3 Foot Baseboard Complete with 3/4 Inch Element

Product Description

The Sterling sus-3 Suntemp baseboard heating unit is a complete 3-foot hydronic baseboard assembly built for residential and light commercial hot water heating systems. This unit ships ready to install and includes the baseboard enclosure along with a 3/4 inch sweat-connection copper and aluminum heating element. Hydronic baseboard heaters work by circulating hot water from a boiler through a finned copper tube element. The fins transfer heat from the hot water into the surrounding air, warming the room through natural convection. HVAC technicians and plumbers rely on baseboard units like the sus-3 for zone heating, radiant hot water distribution, and baseboard replacement projects. The Sterling sus-3 delivers 1,680 net BTU per hour at 180 degrees Fahrenheit water temperature and a flow rate of 1 gallon per minute. This output rating makes it suitable for supplemental zone heating or smaller room applications. The enclosure is painted white and measures 2 and 13/16 inches thick and 7 and 7/8 inches tall, fitting standard baseboard profiles common in residential construction. The element uses a 3/4 inch sweat connection, compatible with standard copper pipe runs in forced hot water systems. The unit weighs 7 and 1/2 pounds and does not include a splice plate. Installers working on multi-section runs should order splice plates separately. The aluminum fin construction maximizes heat transfer efficiency from the copper tube. This unit is a direct solution for baseboard heater replacement, new hydronic zone installations, and contractor supply orders requiring a complete, paint-ready enclosure with an integrated element.
