Tile underfloor heating using the AHT Ribbon
tile underfloor heating is very easy to do and does not increase your floor heights dramatically, see below for layout.
1 Tile or Stone (5 - 18mm)
2 Flexible Tile Adhesive (8mm)
3 Ribbon Underfloor Heating (2mm)
4 Easy-Heat insulation (10 - 50mm)
5 Flexible Tile Adhesive (3mm)
6 Concrete / Wood Subfloor
Layers under tiles

Floor Preparation.
When installing tile underfloor heating there is very little floor preparation needed, it is important that the subfloor is flat, smooth and dry (Latex level compound may be needed). When the floor is flat ensure that it is free from dust and debris.
Installation Steps
- Dry lay your Easy-Heat insulation (cut to shape with a stanley knife)
- Once you are happy that all the boards will fit, remove the boards remembering where they will go.
- mix your Flexible tile adhesive and spread over your subfloor (3mm notch trowel) and replace the Easy heat insulation applying a bit of preasure to ensure it bonds.
- Allow the flexible tile adhesive to set, if using rapid set flexible adhesive you should be able to walk on the insulation within 2 hours.
- Lay down your ribbon heating mats using the double sided tape on each end of the heating mats.
- Where required use allbrite's high adhesive tape to secure the edges.
- Route the cold leads (live & neutral) to a junction box just above skirting board level
- Check the resistance of the heating elements matches with the resistance chart in installation manual
- Connect the cold leads using the revolutionary 5 lever quick connectors
- Using a 10mm notch trowel spread an even bed of flexible adhesive and lay your tiles, slate or stone.
- See Electrical section for setting up electrics, if installing in a wet area please see grounding kits.
- Sit back and enjoy.
