DEVIcomfort Heating Mat - Installation

  • Installation is a relatively simple affair, first measure your floor in rectangles to see how many mats you’ll be needing.  If installing over concrete floors, it is advisable to lay insulation boards to minimise heat loss, ensuring quicker warm up times. Lay the first run of the mat, cut it at the end (leaving the cable intact), then turn the mat through 90 degrees or 180 degrees and continue laying. 
  • When done laying, attach the mat to the subfloor using the special tape provided. Install a Residual Current Device (RCD) fused spur to power the controller/ programmer and the mat system. Lay out the timer-thermostat onto the floor, with an equal distance between the two cable loops, then attach it to the floor surface. 
  • Now take the unheated power supply from the end of the mat system, which ought to be positioned near the thermostat. Once all connections have been sourced to the power supply, run the heater to ensure they are running properly (for no more than 10 minutes).
  • Lay a thin self-levelling screed over the mat, and then leave it to dry. After this, place the tiles or trowel flexible adhesive directly over the mat before laying the floor tiles over. Once you have completed the grouting, leave the tile adhesive to cool before turning the system on.

Typical areas for installation are Concrete floors, Indoor floor heating in domestic and public buildings, Very thin floors - perfect for renovating projects.
