Water underfloor heating and epoxy grouts
Hello,
I did some reading here and there, but the opinions seem to diverge at some point and I am not able to translate the info to my particular question. I have a water underfloor heating (thermal pump and so on) installed and am currently having the bathrooms (and not only) done. I am wondering about getting the epoxy grout (PCI Durapox premium), as there seem to be 3 opinions that sound equally reasonable to someone like me (zero prior knowledge):
Can anyone share actual experience and/or some theoretical base so that I can educate myself on that ? They seem to have 3 of the 4 colors I need on the epoxy, so I can do most of the space with it, as long as I do not risk having cracks in the tiles in a few years because of this. The guy that is installing the tiles is really good in what he does and I am 99% sure that the installation itself will be good, just wondering if there is more to it than just installation (like physics laws or something that we cannot fight).

- some say to avoid epoxy grout in this case as it is very hard and the thermal expansion may break the tile due to no room left for it
- some say that the above is possible, but fixable by leaving a non-epoxy joint every X meters or something
- and finally, some say that the thermal expansion should not be significant enough to cause breaking of the tile due to the not too high temperatures it reaches
