Sterling HTA-55RB-750A3 Hydronic Baseboard Element 3 Foot

Product Description

The STERLING HTA-55RB-750A3 is a complete hydronic baseboard enclosure and heating element assembly from the Heatrim line, designed for hot water baseboard heating systems. This unit includes both the enclosure and the element as a matched assembly, simplifying replacement and reducing the risk of mismatched components. It covers a 3-foot run of baseboard, making it suited for room perimeter heating in residential and light commercial applications. Licensed HVAC and hydronic heating technicians are the typical installers for this type of component.

This assembly is intended for use in hydronic baseboard heating systems where a 3-foot section needs to be replaced or installed. The Heatrim series is a long-established product line in hydronic perimeter heating. The complete enclosure-and-element format means the housing, element, and end caps are included together, which is appropriate for full-section replacement rather than element-only service. It is suited for residential rooms, hallways, and smaller commercial zones served by a hot water boiler circuit.

Key Features

• Complete assembly includes both the enclosure and the heating element
• 3-foot length fits standard baseboard heating runs along room perimeters
• Designed as a direct replacement for Heatrim-series hydronic baseboard sections

Compatibility

Installation Notes

Installation should be performed by a licensed HVAC or hydronic heating technician. Drain and depressurize the hydronic circuit and shut off the boiler before removing the existing baseboard section. Ensure all pipe connections are properly fitted and tested for leaks before restoring system pressure. Local mechanical codes, including applicable provisions of the International Mechanical Code, should be consulted before installation.
