The problem with these heat pads is the expantion and contraction of the materials around it(above and below) when the heat comes on and off.
With a tile floor, I feel the best way to go is to use a wall mastic. It will allow some movement of the materials, unlike thinset’s. Some tips to avoid problems with the grout. Make sure the heat it on at the temperature the room will be upon completion at the grouting stage. Keep the heat on well after while the grout sets up. Use a good sealer with two coats on the joints. Make sure the underlay is well beyond the minimum requirement in thickness and avoid laminating with different materials. You want to have as little movement as possible. Some materials expand at greater rates and speeds than others. By the way I like the NuHeat system aswell.
Good luck!

Anyone have any experience, recommendations or suggestions about electric under-floor heating systems for ceramic tile floors?
I've looked at NuHeat and EasyHeat. Not impressed by EasyHeat. Liked NuHeat, but it was a little pricey.
TIA,
