Under-tile heating mats by nVent Raychem

These are our thinnest heating cables suitable for your renovation needs as they can be laid directly under your tiles in a cement-based adhesive

Under tile heating mats

If you are planning to renovate an existing floor, QuickNet floor heating mats are the most economical, luxurious and practical form of space heating you can buy. 

During renovation, electric heating mats are rolled into position prior to the screed being laid. These mats heat the floor during regulated heating periods. 

How to install

Unlike traditional heating systems there are no ducts, fans, consoles or vents required. This frees up your wall and floor space giving you the freedom to decorate your interior without interferences.

Discuss it at your initial planning stage with your architect, builder or specialist heating installer.

Measure your heating area

Using the examples below, measure the floor area you need to heat. 

Note: do not calculate permanent fixtures (wardrobes and benches) as heating areas.

Heating area


Living room example A

Heating area = 4.1m x 5.1m

       = 20.9m²

Example A selection

Bedroom example B

Room area = 2.1m x 4.1m

                    = 8.6m²


Area of fixtures = 2m²


Heating area = 8.6m² - 2.0m²

                       = 6.6m²

Example B selection

Bathroom, toilet, laundry
example C

Room area = 2.0m x 3.75m

                    = 7.5m²

Area of fixtures = 2.2m²
(bath, shower, toilet, bench)


Heating area = 7.5m² - 2.2m²

                       = 5.3m²

Example C selection

After measuring your desired heating area, refer to the table to locate your suitable product (unit).



Floor coverings

Most types of floor coverings can be used, for example carpets (wool or synthetic), vinyl tiles, ceramic tiles and slate.

Bitumen backed carpet tiles are not suitable. 

Cork tile and parquetry must be laid on a dry floor. In other words, this must be laid after initial use of the heating system to evaporate the moisture remaining in the concrete floor.

Depending on the type of tile, a waterproof adhesive (such as a two-part latex adhesive) or mortar-bed fixing system must be used. Some adhesives (particularly the water based latex adhesives) will deteriorate and soften at temperatures above 40°C. The adhesive chosen should be capable of withstanding temperatures of up to 60°C without a loss of bond strength.

Gentle background warmth

The heat stored inside the floor is emitted from the whole surface area, giving an almost even air temperature from floor to ceiling. Warmth is produced where it is required most, underfoot, and then radiates throughout the area. 

CSIRO tests show that where floor level temperatures are around 16°C people feel comfortably warm all over. When floor level temperatures are lower, people feel cold even if the temperature at head level is over 21°C. 

nVent Raychem T2 QuickNet floor heating is the energy - efficient way to provide a constantly comfortable room temperature.

Economical and Energy efficient

Heat input to the floor is controlled by wall-mounted or in floor thermostats. Heating in each room or zone is controlled by a separate thermostat, so energy need never be wasted. 

The system takes advantage of low-cost off-peak electricity or time of use tariff available in most areas. When normal rate electricity is being used the system can be regulated by a time clock. Check with your local electricity authority regarding off-peak power availability in your area. 

The floor stores enough heat during the off-peak charge period to maintain a comfortable temperature for the full 24 hours. Heat storage is topped up again during the next heating period.
