Undertile Heating

Step 1
Measure the room and draw a sketch to help you calculate which DEVI package you will need. Then sketch in the position of the Devimat heating cable mat.

Step 2
Mark the positioning of the toilet before you remove it. This helps you avoid placing the toilet on top of the mat - and prevents you from piercing it with screws.

Step 3
Cut a channel approx.10mm deep & wide in the wall from the thermostat & about 1m out into floor. Glue flex pipe for the sensor into channel, & seal end of the pipe with piece of tape.

Step 4
Clean the floor thoroughly, removing all dirt and soap residue, then lay out the self-adhesive cable mat. The floor surface must be primed if you are not laying the mat on existing tiles.

Step 5
Clip through the grey netting to turn the mat over - but make sure that you do not cut through the red cable!

Step 6
Turn the mat and position it as required. The self-adhesive effect can withstand 10-20 adjustments, so you can move the mat several times until you are satisfied with the result.

Step 7
Once you have positioned the cable mat, you can - depending on the new floor surface - encapsulate it using self levelling screed or cover it with a thin layer of tile adhesive.
