I've installed the under slab kind, and we used a number of zones that overlapped in case one of the zones leaked. You would just shut it off at the manifold, and didn't have any big dead spots.
Now, my firend had a new ceramic tile floor installed, and he put in some of the electric stuff. It works great, I just saw it today, and it was 4 degrees outside. You could really tell.
