The Heatmiser 230V actuator is a reliable thermal actuator designed for precise control of water underfloor heating systems. Installed directly onto the manifold, it regulates water flow to individual heating loops based on thermostat demand. As a result, it ensures accurate temperature control and consistent comfort in every zone.
Designed for use with 230V wiring centres, the Heatmiser actuator operates in a normally closed position. When a thermostat calls for heat, the actuator opens to allow warm water to flow through the underfloor heating circuit. Consequently, heat is delivered only where required, improving overall system efficiency.
The Heatmiser 230V actuator is compatible with a wide range of underfloor heating manifolds using standard M30 x 1.5 connections. This makes it suitable for both new installations and retrofit projects. Therefore, installers benefit from flexibility and ease of integration across different systems.
One of the key advantages of this actuator is its dependable thermal operation. Once energised, it opens smoothly and quietly, ensuring stable water flow without sudden changes. As a result, underfloor heating systems operate more efficiently and with minimal wear on components.
Installation is quick and straightforward. The actuator simply screws onto the manifold valve and connects to the wiring centre using clearly identified cables. Furthermore, its compact design allows neat installation even in confined manifold cabinets.
The Heatmiser 230V actuator works seamlessly with Heatmiser wiring centres such as the UH4, UH6, and UH8 models. This compatibility ensures reliable communication between thermostats and heating zones. Consequently, system commissioning is faster and more reliable.
