set a toto

Super toilet
simple set on a internal pvc flange what is the best product to use in a hydronic radiant heat slab running 110 degrees ? Will a regular wax ring hold up?
Thanks to all

Probably, but I'd consider one of the waxless from either Fluidmaster of (I think) Fernco. I used a couple while remodeling when I needed to install and remove the toilet a few times...made it much easier and less messy. Seems to work fine, and has been around for 5-years now.
