Heatmiser TA230 2 Wire Thermal Actuator

Heatmiser TA230 2 Wire Thermal Actuator

The Heatmiser TA230 2-Wire Thermal Actuator is a high-performance 230V actuator designed for precise control of underfloor heating and manifold valve systems. Compact, efficient, and reliable, it offers smooth operation and long-lasting performance in both residential and commercial UFH installations.

This normally closed (NC) actuator opens the valve when powered, ensuring accurate temperature regulation across each heating zone. Its M30 × 1.5 threaded ring nut provides universal compatibility with most underfloor heating manifolds, making it ideal for new installations or replacement applications.

Built to exacting Heatmiser standards, the TA230 combines low power consumption (only 2W) with fast response times — opening in approximately 120–180 seconds. The IP54-rated housing ensures durability in manifold cabinets and other protected indoor environments.
