Installation of electric underfloor heating with approximate installation times

This article will discuss installation methods and times for electric underfloor heating mats over most floor coverings. You can also refer to main website for installation techniques and prices for systems under wood and carpet or tiles, Karndean or Amtico.

This article only gives a summary of the installation steps. Before installing electric underfloor heating mats your should always read the far more comprehensive installation manual.

Installation of Electric underfloor heating mats vs loose cable

The advantages of Electric underfloor  systems which come as a loose cable is cost of kit. In very small areas with a very irregular shape it may be easier to install.

Electric underfloor heating mats however are far quicker and easier to install. As the cables are always the correct distance apart you eliminate the potential problems of hot and cold spot that you could have with loose cable electric underfloor heating systems.

Installation of electric underfloor heating under tiles

Laying the insulation

(1)    The insulation for under tiles always comes in the form of a dense board (eg Insomax). This board needs to fixed to a clean subfloor with a suitable flexible tile adhesive.  The normal method of applying tiles adhesive is to use a trowel with ridges to get a flat surface.

(2)    Once all the insulation has been fixed then perform a full electrical test on all the electric underfloor heating mats.

(3)    Next is to roll out and fix the electric under floor matting onto the floor according to your floor plan.  Make sure you always buy from a company that will provide a full floor plan to avoid any problems. Rayotec provides free floor plans with all purchases.

(4)    Fully test all the mats again

(5)    Install your thermostat

(6)    Lay your tiles/stone floor onto using a flexible tile adhesive.

 

Time to install

  • One man can fix about 50m2 of Insomax insulation in half a day.
  • Two men can stick down 50m2 of mats and test them in half a day.
  • The electrical connection time depends on the number of zones/thermomstats required

 

Installation of electric underfloor heating mats under Amtico, Karndean or Vinyl.

The installation method is exactly as when installing under tiles but the electric underfloor heating mats have to be covered with a minimum of 8-12mm flexible self levelling compound before sticking the Amtico, Karndean or Vinyl ontop.

Time to install

  • One man can fix about 50m2 of suitable insulation (tile backer board) in half a day.
  • Two men can stick down 50m2 of mats and test them and cover in a flexible self levelling compound in one day.
  • The electrical connection time depends on the number of zones/thermomstats required

Make sure that the insulation used is suitable for the self levelling compound and the potential traffic and point loading that it could be experiencing.

 

Installation of electric underfloor heating under wooden floors or carpets

Although it is common for companies to supply traditional foam boards I have written these instructions using Palziv insulation as it much faster and easier to use and has better sound deadening properties.

Laying the insulation

(1)    Fix the Palziv insulation down using double sides tape or carpet spray onto a clean floor.

(2)    Once all the insulation has been fixed then perform a full electrical test on all the electric underfloor heating mats.

(3)    Next is to roll out and fix the electric under floor matting onto the floor according to your floor plan.  We recommend the Rayoflex mats due to build quality and ease of insulation. Make sure you always buy from a company that will provide a full floor plan to avoid any problems. Rayotec provides free floor plans with all purchases.

(4)    Fully test all the electric heating mats again

(5)    Install your digital thermostat

(6)    Lay your carpet & underlay or float your wooden floor on top. It is important to make sure that the tog value of the carpet and underlay and the thickness of the wood do not go above the maximum permitted to allow the heat to pass through.

Time to install

  • One man can fix about 75m2 of Palziv insulation in half a day.
  • Two men can stick down 50m2 of mats and test them in half a day.
