The Heatmiser UH4 Wiring Centre is a compact control hub for underfloor heating systems, designed to manage up to four heating zones. It's ideally suited for smaller installations or properties with fewer zones, offering centralised control and reliable system integration.
The UH4 provides 230V outputs for zone actuators and includes dedicated connections for a domestic hot water cylinder, system boiler, and pump. It also features the flexibility to control a single radiator zone, making it suitable for mixed heating environments. The UH4 is compatible with mains voltage thermostats, offering a wide range of setup options.
Compatible Thermostats:
DS1 V2 | Slimline-RF | NeoStat V2 White / Black / Platinum | NeoStat WiFi – White / Black | Fastwarm Smart WiFi 2.0 – Black / White
Whether you're planning a compact heating setup or need an efficient control option for smaller properties, the UH4 delivers essential features in a space-saving design. Key functionality includes:
- 4-Zone Control – Ideal for small-scale underfloor heating systems or single radiator zones.
- 230V Actuator Outputs – Supports standard actuators for efficient zone control.
- Boiler and Pump Output – Includes wiring for central control of the system boiler and circulation pump.
- Hot Water Cylinder Output – Enables DHW control alongside heating zones.
- Compact Form Factor – 384mm x 148mm x 60mm (LxHxD), perfect for space-conscious installations.
For larger or wireless systems, consider alternative wiring centres like the UH8, UH8-N, UH8-RF, or Fastwarm 10-Zone Wiring Centre.
