Suntemp SUS-3 3' Baseboard Heater Complete - 700 Series - 3/4" Element

The Suntemp SUS-3 is a complete 3' length of 700 Series (Imperial 700-A1) hydronic baseboard: enclosure plus 3/4" copper heating element. It is used on hot water heating systems as perimeter heat under windows and along outside walls.

Suntemp ratings include a 15% allowance for heating effect and are based on active length, which is total length less 4-3/4". The 4 GPM ratings apply only where at least that flow actually passes through the baseboard.

Key features

• Low 7-7/8" by narrow 2-13/16" enclosure with a satin-white baked finish
• Damper-louver adjusts from full open to closed by touch; front outlet keeps air off the wall to prevent streaking
• Locking front panel latches to the support brackets
• Concealed return tube hanger tucks a return line inside the enclosure
• Copper tube element with deep-drawn fin collars and channeled fins (36% more fin surface than a flat fin of the same length, per Suntemp)
• Polypropylene expansion cradles isolate the element so expansion does not cause ticking noises
