cracked tile over heating mat

[missmouse]

any tips on how to remove a cracked floor tile fitted over electrical heating without damaging the wires?

this sounds drastic but hit the tile with a hammer in the middle or just to the side.

it will crack and you can take out the broken pieces without pulling up the wires.

are the wires in self levelling, or are they just in the tile adhesive.

should always is a self levelling like
