Hi, this is my first post on this forum – so go easy!! 
I have brought a wet under floor heating kit (16mm piping) for my bathroom and kitchen. I am trying to come up with a solution whereby I can get away from increasing the floor height too much.
I currently have a pretty flat concrete base cover in ash felt and I want to build on top of this. I can a couple of idea, what do you guys think?
1st Idea
Use washers and screws or some sort of adhesive to bond the 40mm kingspan to the concrete floor.
Cut 8mm groves using a router into the insulation pushing the pipes into grove.
Using latex screed cover 8mm showing the piping
Tile slate (600x300 tiles) on top of this using flexible tile adhesive
2nd Idea
Use washers and screws or some sort of adhesive to bond the 40mm eko board (solid foam) to the concrete floor.
Cut 14mm groves using a router into the insulation pushing the pipes into grove.
Using latex screed cover 2/3mm showing the piping
Tile slate (600x300 tiles) on top of this using flexible tile adhesive
3rd Idea
Use washers and screws or some sort of adhesive to bond the 50mm eko board (solid foam) to the concrete floor.
Cut 16mm groves using a router into the insulation pushing the pipes into grove.
Cover the insulation with primer
Tile slate (600x300 tiles) on top of this using flexible tile adhesive
What do you guys think? I don’t really want to use 60mm sand and cement
