1mm is better. There is not much room in those wiring centres to get all the cables in, so the smaller the better.

 

Ok, even better then, as I may have to share the conduit in a couple of walls with cabling for light switches.

 

Thanks very much all! Another job for this coming week then!

I have been specified the same thermostat X 14 from Wunda for our wet UFH,  however the design is not quite doing it for me, are there any alternatives any one can recommend?

Thank you. @PeterW  @Nickfromwales

What do you need from each stat? Temp only / temp + time clock etc ? Are you having a central hub to set times etc ?

Hi Nick

Just wanted to be able to set each stat  temp time / 7 day week etc, Had not planned on a central hub but could be persuaded. Wunda have not offered this as an option.

 

[Nickfromwales]

You dont have to use Wundas stats  Find out if theyre 230v signalling or 12 / 24v / other and then you can look at stats you like the look of and mix n match. 

What your looking for is called a 'programmable room thermostat' btw.

These are quite pleasant.

Wunda have offered Heatmiser as an alternative. Perfect for the price.

Hi Lizzie

Does it all work ok, do you set each room independently or off a central hub, Wifi or wired?

We have heatmisers, 7 neos, 1ultra and the hub. Works well, good app.  Can’t fault it really! 

[Lesgrandepotato]

You can set each room independently. Or all from the Ultra, or all from the app.

Yes set each room individually or from app.  You can set a profile to have different times/ temps different rooms or all the same....my fave programme is nicknamed ‘toasty’ LOL.  Heatmiser works fine once you get it set up was an absolute bugger to get going initially though.I’m happy with it now Ive worked it out.

I have one of these as it was bought in the days before the app was available. It probably does a similar thing to the app but it is on the wall in the kitchen and I can control all rooms from it.

Can someone tell me if I've ended up getting the wrong cable? I went and bought 6243Y 3X1+1 1mm from TLC: https://www.tlc-direct.co.uk/Products/CA1slash3G.html

 

But it seems overkill to me (bearing I am no electrician) for what is only linking the thermostats to the ufh control board. Even the cable clamps in the wiring centre won't be able to clamp that cable down:

 

 

 

 

Did I get the wrong stuff? Surely this would suffice? https://www.tlc-direct.co.uk/Products/CA0dot75HR4.html

 

 

If not, it'll be a bugger to get the wiring centre all connected (leaving that for electrician):

I'm sure the stuff I used in the last house was round in section and each wire was made up of multiple strands of copper wire, thus more flexible.

You should have got flexible cable, number of cores to suit, as the solid core stuff is for fixed wiring only. The Basic stuff is for wiring between the CU and the fused disconnection unit, and then you can use flexible cable, suitably protected in a trunking where practicable, which would be far easier. Also no need to earth sleeve anything as the earth will already be a PVC coated core.

Thanks @Triassic and @Nickfromwales. I thought I'd gone wrong. I'll get some 0.75mm2 flex. On offer from SF at the mo at only £18 not including my 10% off!
