Multi zone underfloor heating systems
Multi-room systems are used when you would like to control the heating in different rooms at different times and temperatures, the main difference between this system and a standard room kit is that it is supplied with multiple thermostats and a wiring centre, the wiring centre allows the switching on of different zones at different times.
Each manifold port can control up to 100m of pipe each zone is controlled by the actuator valve on the manifold – so when the system calls for heat (i.e. your thermostat is set to come on) the valve opens up and lets the water flow down the pipe. If you are planning on combining this system with an existing radiator circuit then it should be installed independently at the boiler with a new 2 port motorised valve on an ‘S’ plan type system.
