Question Tips for installing radiant flooring in basement?

I'm putting in a radiant floor in my basement that has a concrete floor and then tiling over the bathroom area and cork over the work area. I have chosen the Schulter DITRA-Heat system. It will be covering @ a third of the entire basement space.

Has anyone any experience installing these and might have some tips or recommendations or how well the system works?

A vaper bearer is just a thin mastic type thin-set product that you trowel on, right? And then you roll/adhere the pad that you weave the wires through and then you thin-set mortar and then tile, grout. The cork is floating and not sure if it should also be thin-set down and I'll deal with that when I get it. I have a dedicated 20A line so everything will be to manufacturer specifications.

Thanks in advance.

I have not done a DITRA-Heat system floor heat but I have done embedded heat cables before. After the cables and sensors are installed you will want to cover it with a self-leveling product to embed the cables. I would not recommend relying just on thin-set to embed the cables and stick the tile at the same time. The floating floor should be installed as a floating floor, not stuck down.
