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

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

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.
