Anyone know about floor tiles and wet underfloor heating?

[JessieMcJessie]

Our kitchen has these nice terracotta tiles but the grouting is all over the place and clearly an amateur job. There is wet heating underneath which works really well. We're having the kitchen redone soon and I am keen to either replace the tiles altogether or get them re-grouted. I am presuming they could be taken up without damaging the underfloor heating, is that right?

Or if we choose to keep them, is re-grouting realistic or more bother than it's worth?

We're just installing underfloor heating, our pipes are installed under a layer of screed so based on that I don't think you would damage the pipes unless you were really going for

It! Sorry!
