Enquiry Form

Selecting the required mat or mats for a room is a simple four step process.

Check floor surface

M Series heating mats are most commonly installed under tiles either in flexible self-levelling compound or directly into the tile adhesive.  However M Series heating mats are frequently used with other floor surfaces such as carpet, vinyl, laminate and engineered wood with the heating mat being completely covered in a flexible self-levelling compound which is allowed to dry before the floor surface is applied.

If there is any doubt about the suitability of any given floor surface for use with underfloor heating, confirmation should be sought from the flooring supplier.

Choose between standard output, high output or low output mat
Standard Output (150W/m²)

Other than in exceptional circumstances, standard output mats will provide a sole source of heat in a room

High Output (200W/m²)

High output mats should be selected when one of the following applies:

  • A room has exceptionally high heat losses (this may apply to some conservatories)
  • A rapid heat up is required perhaps because a room is rarely used
  • It is only possible to heat a small percentage of the total floor area
Low output (100W/m²)

Low output mats are often specified for properties with high levels of insulation.  The use of low output mats reduces the power demand for any given room and means that larger areas can be controlled by a single thermostat without the need of a contactor.

Typical M Series Installation

Select the correct size mat or mats

The objective is generally to cover as high a percentage of the free floor area as possible.  The free floor area is defined as the floor area not occupied by permanent fixtures such as kitchen cabinets and shower trays.  As a rule of thumb, we suggest selecting a mat with a total area approximately 10% less than the total free floor area.  This will allow for perimeter spacing and ensure easy installation.  In larger rooms it is common practice to install more than one mat.

Select insulation boards
F-Board

To limit downward heat loss and to significantly improve economy, the use of F-Board insulated tile backer board is highly recommended.  The use of F-Board insulation is particularly important when heating mats are installed on top of an un-insulated concrete slab.  F-Board is available in two thicknesses: 6mm and 10mm.  We recommend using 10mm board except when it is vital to keep the floor height to a minimum.  Each board covers an area of 0.72m².  Therefore to select the correct number of boards, simply divide the total floor area by 0.72.

F-board is lightweight and easily cut to shape.
