Sterling Hvac HTA-55RB-750A5 Baseboard Heater 5 Foot

Product Description

The STERLING HVAC HTA-55RB-750A5 is a complete hydronic baseboard heater enclosure and element assembly designed for hot-water heating systems in residential and light commercial applications. This unit ships as a full assembly combining the enclosure cabinet and the fin-tube heating element, simplifying replacement and reducing installation time. At 5 feet in length, it delivers radiant convective heat along the baseboard perimeter of a room, integrating with existing hydronic piping loops. Licensed HVAC technicians and plumbers working on hydronic systems will find this a direct-replacement-style unit ready for field installation.

The HTA-55RB-750A5 is suited for residential rooms, offices, and light commercial spaces served by a central hydronic boiler system. It is installed along exterior walls or under windows where heat loss is highest, drawing cool air at floor level and releasing warm air upward through the enclosure louvers. This 5-foot unit is appropriate for zones requiring perimeter baseboard coverage where a standard cabinet-length element assembly is specified.

Key Features

• Complete assembly — enclosure cabinet and fin-tube element included as one unit
• 5-foot length suitable for standard perimeter baseboard heating layouts
• Heatrim-style design provides efficient convective heat distribution along the floor line
• Designed as a drop-in replacement to minimize downtime during service calls
• Compatible with standard hydronic hot-water piping connections

Compatibility

Designed as an OEM-style replacement for hydronic baseboard heating systems using Heatrim-style enclosure and element assemblies. Verify pipe connection size, element length, and enclosure dimensions against the existing installation before ordering.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with hydronic heating systems. Shut down the boiler and depressurize the affected zone before disconnecting supply and return connections. Follow local plumbing and mechanical codes, including applicable sections of the International Plumbing Code, for pipe connections and system pressure ratings. Do not restore system pressure or fire the boiler until all connections are secure and the enclosure is properly mounted.
