Sterling HTA-55RB-750A4 Hydronic Baseboard Heater 4 Ft

Product Description

The STERLING HTA-55RB-750A4 is a complete hydronic baseboard heater enclosure and element assembly from the Heatrim product line. This unit combines the heating element with its enclosure in a single 4-foot assembly, designed for hot-water baseboard heating systems in residential and light commercial applications. It is intended for installation by licensed plumbers, HVAC technicians, or hydronic heating specialists working on forced hot-water distribution systems. The complete assembly simplifies replacement by delivering the enclosure and element together, reducing parts sourcing and on-site assembly time.

This assembly is suited for hydronic baseboard heating zones in residential homes and small commercial spaces. It is typically installed along exterior walls and perimeter floor lines where heat loss is greatest. The 4-foot length fits standard bay and room configurations common in residential construction. Contractors replacing aging Heatrim baseboard sections will find this a direct-fit solution that restores system output without modification to existing piping rough-in.
