Underfloor Heating

[bluecallum]

Can someone let me know the wiring procedure when underflooring heating is being installed by flow and return piping,and seperate room stats are required for rooms.so six rooms and each room having its own stat which are wired and not wireless.

you need to talk to the plumber and find out what system he is installing.

If i remember rightly i think he said a y plan system

If it's a y-plan and there not piped individually with actuators for the stats to open them, the only way is all stats in parallel and if any one of them calls it will bring the whole heating side of system on, bit rubbish if this is the case.

Usually the kit comes with a wiring centre for all the stat cables and actuators to connect to

You need to know what equipment he is installing in terms of manufacturer.

Underfloor heating for 6 zones will need a central controller that communicates with the room stats/controllers and controls the manifold valves. Depending on the manufacturer you could need:
simple T & E
4/5 core cable
or even ethernet type cable.

 

[bluecallum]

ethernet cable sound like this is going to become a nightmare.

just get the details from the plumber and you should be able to get the wiring diagram required and then decide what cabling is required.

Depending on which type of Programmable stats your using, but for example if it was a heatmiser 12v system I would have a cat5 from each stat back to my wiring centre, then were ever your zone valves are, have at least 3 cores back to your wiring centre there. The wiring centre (UH1) would be near the manifold I hope, therefore your pump, pipe stat and zone actuators can all be surface...
