Underfloor heating - Replacing a floor tile - Wires under tiled floor

[Conshine]

Hi - I have under floor heating in the bathroom.

One of the tiles was cracked, so I took a good one up from an area under the bath that is now covered up with the bath panel anyway.

It was extremely difficult to get the broken tile up, but got it eventually.

In taking up the broken tile, I have exposed some wires - They seem to loop around - I assume that the wires heat up when the heating is on and there is a network of these wires under the tiles.

Under the wire sems a plastic mesh of some sort.

Also, the broken tile seemed to be on a bed of sticky rubbery type material.

I was considering just some cement to put the good tile down, as its hardly worth the cost of a bag of floor laying cement for one tile.

Am concerned about laying wet cement directly on the wires.

Also, the concrete may crack when the floor heats.

Whats the plastic mesh all about?

What do you recommend I use to put the new tile down?

Cheers!

It will crack! It would be a false economy not to use proper flexible adhesive intended for use with underfloor heating.

Adhesive latice, the ufh wires are attached to this to ensure correct spacing and easy installation.

Are the wires damaged in any way?

While I can't advise on a solution, as you seem unsure about the mesh etc. what you have is some version of electric underfloor heating. We have it in a few rooms under tiles and works quite well. Allows you to have heat in one room rather than firing up the boiler for the whole house. Is really an addition to main heating rather than stand alone as would be fairly expensive to run if using everywhere. We have in bathrooms and sunroom.

(no connection witht he company in the link, it's just their product we have installed)

Cant tell if they are damaged or not - They are kind of encased within the adhesive - Difficult to tell.
What if they were damaged and I cant see it?
