I am just laying out our UFH, on the drawings, ready to put them into the slab and I am trying to work out where they cannot go. I appreciate that services coming up through the slab must be avoided but my worry was what fixings might need to go more than 100mm, our slab is 150mm thick with the 16mm UFH at the bottom, into the slab and therefore must be avoided. I was making a list:
1. Fixings for the sole plate (outer walls).
2. Fixings for sole plate of internal stud partitions.
3. Fixings for the internal steel columns.
4. Fixings for the toilet pans if I cannot sort wall hung (or some later occupier might want to fit floor standing).
5. Fixings for the base of the stairs.
6. Fixings for the kitchen island unit.
7. ???
8. ???

Other questions which feel like I know the answers as to where the pipes must go, under the downstairs wet room shower tray former and into the downstairs WC.
