Warmup WHP1, Installation Manual

13

Suitable wall Coverings 

The Warmup heating panels are designed to be installed behind ceramic or natural 
stone tiles. 

Adhesive and Grout 

The tile adhesive and grout must include an additive for flexibility and be suitable 

for use with underfloor heating. Refer to the adhesive manufacture’s instructions 

for usage. 2 part flexible adhesive is best. 

Tiling Over the Heating Panel 

In order to make tiling over the heating panels easier the wall heating panel 

should be tiled over using a Two-Step Method:

1. Completely cover the heating panel with a 10mm layer of flexible adhesive and 

allow this level to dry. 

2. Apply another layer of flexible adhesive and tile as normal.

It is important that each tile is solidly bedded in adhesive, with no air gaps or voids 

beneath. Do not allow the trowel to make contact with the heating wire while 

applying the adhesive. 

If a tile has been positioned incorrectly, take 

great care not to damage the heating wire when 

lifting. Remember that tiles must not be lifted 

once the adhesive is dry, as this may damage the 

heating wire. 

It is important to test the resistance of the 

heating panel regularly during the tiling process. 

If at any time you damage the cable stop tiling 

immediately and contact the Warmup Technical 

helpline on 0845 345 2288 for further assistance.
