Salus THB23031 Auto-Balancing Underfloor Heating Actuator

Salus THB23031 Auto-Balancing Underfloor Heating Actuator

The Salus THB23031 is a cutting-edge auto-balancing actuator designed for underfloor heating systems. Utilising advanced technology and dual temperature sensors, this actuator ensures the dynamic and automatic hydraulic balancing of each heating loop, delivering optimal comfort and energy efficiency without the need for manual balancing or calibration. It monitors and maintains the correct temperature differential (ΔT) between flow and return pipes, providing consistent heating performance in both new and retrofit installations.
