Warmup UFH 1.8mm cable - does it need levelling compound?

[Old Mod]

Sorry not wishing to teach u to suck eggs but u do realise under tile heating is a cable and under wood heating is a foil yeah?

Which areas are having wood? Just the stuff outside the bathroom?

You can still use cable and SLC and then lay the wood on top. I think cant you?

Everywhere bar the wetroom will be engineered wood flooring.
Just checked the warmup site and came across this which suggests he loose wire system can be used underneath wood flooring, just a SLC should be used beforehand (as has been mentioned on here).

Starting the rip out on later this month so should know exactly how much height etc I'll have to play with soon.
Plan though is to ply over the joists, then install tile backer boards/insulation boards, install the loose wire system, SLC and finally tile/wood flooring.

Sounds spot on.

Make sure you update us with pictures of the project during and after!

I'm fitting EUFH to the landing and areas of the 2 bedrooms so my sensor will more then likely be in the landing area as that's were the thermostat will be.
?

Each heated area (room) should have its own heater wire, floor thermostat/sensor and controller. Or at the very least the tiled bathroom area should be a separate "circuit" to the other area(s) and I would seek advise as to if they can be combined on one controller.

Hope I'm not to late with this!

SJPurdy - thanks for the info. I've double checked with Warmup and they've noted each of their controllers can handle a maximum of 16amps. Once I know the sqm of the loose wire I require they'll be able to tell me if I can make do with 1 or will have to purchase more.
I do hope I can use just the one as its a small area that needs heating and tbh for myself there would be no advantage for multiple controls.

Vala my concern is that if you have one controller and heating wire running under two different types of floor then the wire will run at a different temperature under the two floors. The tiled floor will transfer heat away from the wire better than the wood floor. If your floor sensor is under the tiled floor then this will limit the temperature of the tiled floor but I think that the wire under the wood floor will run much hotter which could be a problem. This is why you shouldn't put insulating things like bean bags over a electrically heated tiled floor. Follow the advise of the system manufacturer but make sure they are fully aware of what you are planning.

SJPurdy - thanks for that information. Once I have the sqm of the area to be heated I'll contact Warmup and run through what I plan to do. I'll also specify the wood flooring and tiles that I intent to use and see what they come up with.

I was planning on putting the sensor under the wood floor. Would this change anything?
Then the temperature would be dictated by the heat of the wood area. So the tiles, if they are harder to heat, would simply run cooler?

Are there any controllers out there that can control 2 areas independantly?
