thread507-315447: Radiant Piped Heating in Suspended Slab?
We have 3 1/2" LWC on 3" composite metal deck (total 6 1/2" thick), spans 11'-0" , total load 110 psf. The owner wants to install 1/2" plastic pipes at 9" o.c. in the structural slab. The pipes run parallel and perp. to deck in a serpentine fashion.
ACI 302 - Guide for concrete floor slab construction requires 2" concrete cover under the pipe and 2" to 3" cover over the pipe.
I have never done in-floor radiant heating.
Any help would be appreciated.

Detail on Uponor website shows 3/4" thick concrete over tubes.
The detail from Watts Radiant cautions about maintaining minimum 2" concrete
thickness above tubing.
We have suggested detail per attached sketch: the WWM supported on
deck and tubing secured to WWM. We have also added 4 feet wide strip of WWM
over all beams and girders to mitigate cracking.
Does embedding radiant tubes affect fire rating performance of the floor assembly?
I would appreciate your thoughts on the suggested detail.
