Heatmiser TA230 Underfloor Heating Actuator

The Heatmiser TA230 Underfloor Heating Actuator is a reliable, efficient 2-wire thermal actuator designed for precise control of individual valves on an underfloor heating manifold. When signalled by a room thermostat, the actuator opens or closes the valve, allowing for accurate temperature management in each room or zone.

• Power Supply: 230V AC
• Power Consumption: 2W
• Wiring: 2-wire, Normally Closed (NC)
• Valve Connection: M30 x 1.5mm threaded ring nut
• Stroke Length: 3.5mm ± 0.5mm
• Opening Time: Start: 120 seconds, Fully Open: 180 seconds
• IP Rating: IP54
• Maximum Cable Length: 1 metre
• Weight: 127g

The actuator is typically installed on a manifold using the integrated M30 x 1.5mm threaded connection and is controlled via an underfloor heating wiring centre such as the Heatmiser UH4 or UH8, ensuring centralised and efficient operation. Its normally closed design means the valve remains shut until activated, providing energy-saving performance and safety. The robust IP54 enclosure offers protection against dust and water splashes, making it suitable for a wide range of installation environments.

Ideal Applications:

• Hydronic underfloor heating systems
• Integration with Heatmiser wiring centres, room thermostats, or similar systems
• Any project requiring efficient and responsive heating zone control
