The Heatmiser UH8 8 Zone 230v Wiring Centre is a powerful and versatile wiring hub designed for underfloor heating systems, offering central control of up to 8 heating zones. It works perfectly with the Heatmiser TM4 4-channel time clock and DS-SB thermostats, but is fully compatible with any standard 230v room thermostat.
On board, the UH8 includes two heating time channels and lets you assign each zone to follow a specific one. It also features two extra outputs for hot water or auxiliary control, giving installers a high level of flexibility.
Each zone provides a 230v output on demand to switch actuators, the underfloor heating pump, and the valve. A volt-free boiler connection ensures wide compatibility with modern and traditional boilers. Zone 8 includes a slide switch for use as a radiator zone, disabling the UFH outputs and allowing for mixed system setups.
Whether you’re wiring a multi-zone UFH system or combining radiators and floor heating, the Heatmiser UH8 provides a compact, installer-friendly solution trusted across the UK.
