Epoxy Grout on a Heated screed / Under floor heating

[Italy]

the keynote speech was: use epoxy, because one color, almost white, cement based.
gets dirty more, just for that, I proposed Epoxy.
Now, cement-based fillers, reached very high values, both of flexibility, that the color fastness.
that's all.
Then, we know that with other colors, the solution remains the cement base.
(This, for me) 😉

Bisazza' Filgel can also be used over UFH.

I was thinking about the same sort of question the other day due to finding out that the grout specified for all steam rooms were cement based and not epoxy.
I assumed that this could possibly damage the epoxy over a period of time. Maybe someone here could shed light on the matter in my case?
