Tiling requirements for Loose Wire, StickyMat and DCM-PRO

Apply a full bed of flexible adhesive over the wire/mat and tile as normal, taking care not to damage the heating wire. It is important that there are no voids or hollows under the tile. All the heating element must be completely embedded within the adhesive. Grout as soon as possible taking care not damage the heating cable with sharp objects when removing any access adhesive.

Using other floor types with Loose Wire, StickyMat or DCM-PRO.

These systems a primarily designed for use with tiled floors.

In order to use with other floor types, the heating cable must be embedded with a self-levelling compound allow an even spread of heat and project the cable.

Once the system has been installed, lay a minimum of 10mm thick layer of self-levelling compound over the heater which is suitable for use with underfloor heating. You must ensure the entire heater, including manufactured joints are encased in the levelling compound.

Note: When applying self-levelling compound to our heaters, apply in a single pour.   

The self-levelling layer will:

N

Allow a variety of floor finishes to be laid on top such as tile, vinyl, wood and carpet.

N

Provide protection for the heater until the final floor is laid.

N

Give a smooth surface onto which to lay your chosen floor covering.

N

Provide a more uniform temperature distribution.

Important points to remember when installing our electric underfloor heating systems.

M

Do not cut, shorten or alter the length of the heating element – the correct size heating cable for the area must be fitted. Shortening the heating cable will result in failure.

M

Do not tape over the cold lead joint or end joint. Taping over the joints will create an air pocket resulting in the joint overheating and failing. Tab tape the joint to hold in place and ensure there are no air gaps under the tape.

M

Do not leave surplus heating cable under fixtures, units etc. – All the heating element must be embedded with the tile adhesive. Any cable left exposed will result in failure of the system.

M

Do not place heavy/sharp tools (or any other potentially damaging object) on top of the heating mats.

M

Do not turn on the heating before the floor has fully cured – Switching the heating on too early will weaken the adhesive and grout.

M

Do not lay the heater under areas where units will be fitted- Damage can occur from fixtures being fitted to the floor. It is always important that a floor layout is given to other trades, so they are aware of the heating element under the finished floor.

M

Do not space the heating cables closer than 50mm or allow cables to touch at any point – Over time the cable could overheat and fail if the heating wires touch or spaced closer than their minimum spacing. 

M

Do not attempt to repair the heating element – Carrying out a DIY repair will invalidate the lifetime warranty contact Warmup for advice.

M

Do not install the floor sensor near to any other heat source such as a hot water pipe. – This will result in an inaccurate temperature reading and the floor will not operate as expected.

M

Do not lift tiles once they have set – Damage will occur to the heating element if tiles are removed once the adhesive has cured.

N

Always test the heater before during and after installation- Testing the heaters throughout the installation will save you time in resolving the issue and Warmup can provide a quicker resolution before any final floor fishes have been fitted.
