Can a slab be too thick to have UFH pipes in it?
I know a large number of folks on here have insulated slabs where generally the slab is 100mm thick and the UFH pipes are cable tied to the rebar.
We're going this route now for our basement UFH but our slab is 250mm thick with 200mm EPS underneath.
I was just wondering if a slab ever got to a thickness where putting the pipe within the slab became the wrong thing to do?
200mm EPS. I've done the calculations using previously supplied document that @A_L linked here
taking in to consideration the depth below ground.
although it's just occurred to me that the recent change I've made to the insulation levels at ground level has removed 30mm PIR from the slab. s**t. think I need to do some more quick calculations to make sure what I've done hasn't completely messed up my desired U-values. ?♂️
