Wetroom tray & UFH?! - Tile Advice

[Lakey]

Evening folks

I am about to tile a bathroom floor inc, Impey wetroom tray & UFH.
The work up until now has been carried out by someone else and this is where its at.
The floor at present is standard chipboard with the tray being approx 2-3mm proud. I need to run the loose lay cable UFH and encapsulate in a screed. The issue is that the customer wants the UFH in the shower area as well but I can't screed it as it is a center drain. I am pretty sure there is a tanking membrane to go down as well.
So do I run the cable on the floor & tray but only SLC outside the tray then encapsulate cable in the tile adhesive?
Also Is it best to lay the membrane first?
Any advice would be greatly appreciated!

Many thanks

Hi, pretty sure that if you run ufh cables on an Impey tray, you need to lock the stat so the temperature can't go too high.
(Haven't time to check now, and it may be an old memory linked with the bitumen membrane...)

From memory it's dictated by the Impey waterguard tanking - 150w/m2

I don't understand why wattage per should bear any relevance as ultimately it is temperature that will damage it ultimately and as a random figure 30degrees is 30degrees no matter wether it is 150 or 200 watts
