Installation & User Instructions

Every system comes with a comprehensive installation guide. These diagrams show you the general steps for installing underfloor heating under a tiled floor.

Full step by step instructions are supplied with each product and can also be downloaded below.

6-Step Installation Overview

Step 1: Plan and prepare the floor
To help you plan where to install your heating system it may be useful to sketch the layout of the room and mark the area to be heated. Ensure that the subfloor is prepared (smooth and flat) as required for the final floor finish.

Step 2: Lay the system efficiently
These diagrams show how easy it is to install the heating mats in any area and around any obstacle.

Step 3: Start laying the system
Cut the fabric backing and bend the heating cable to fit the room layout.

Step 4: Fix the system in place
Stick your system to the prepared subfloor. We recommend that you prime a concrete subfloor with an acrylic primer before you stick the mats down. Also install the floor probe (supplied with timerstat) between two heating cables. Note: The heating cable MUST always be tested prior to tiling.

Step 5: Apply tile adhesive
Some tilers prefer to tile directly over the heating mat, or apply a thin layer of tile adhesive or self-levelling compound over the system using a non toothed spreader to protect the heating cable from damage.

Step 6: Lay the flooring
Once the tile adhesive or self-levelling compound covering the heating mat has dried, apply flexible tile adhesive and tile.
