In addition to water-based underfloor heating systems, electric underfloor heating is on the rise. More and more homes want to get rid of gas. This is possible if you choose electric underfloor heating . Electric underfloor heating is usually used as additional heating .

Type of electric/infrared underfloor heating

Electric underfloor heating can be divided into three systems:

  • Electric underfloor heating mats
  • Electric underfloor heating cables
  • Heating foil (infrared) 

In practice, the consumption costs of electric underfloor heating are disappointing. Electric underfloor heating is chosen if there is no installation height available and/or you do not want or cannot install pipes for underfloor heating . That is why we recommend electric underfloor heating as additional heating.

Applications of electric/infrared underfloor heating

Electric underfloor heating is often used in rooms that do not need to be heated continuously. Power consumption increases with this system. This makes it economically unattractive if there are no solar panels. For larger rooms it is better to opt for traditional underfloor heating.

In addition, electric underfloor heating is often chosen when there is little installation height or it is not possible to mill into the subfloor.

How does electric underfloor heating work?

Electrical underfloor heating mats: Electrical cables are placed on fiber optic cables. The system is easy to install and has a low installation height. The mats can be placed directly on the screed floor. The mats have a fast heating time. One of the commonly used underfloor heating mats are the mats from Magnum Heating.

Electrical underfloor heating cables: cables in a loop pattern that are installed in the floor. Is often finished with a screed floor. The system is therefore actually a wet construction. The system takes a little longer to heat up, but the floor stays warm longer.

Heating foil (infrared): Very thin foil containing copper heating pipes. An insulating material is often used under the foil. The foil is provided with a moisture barrier where the final floor can be installed on. Foil heats up quickly. The temperature can be controlled separately for each heating zone.

Electric underfloor heating in combination with wooden floors

Wooden floors have been a natural combination with underfloor heating for decades. This also applies to electric underfloor heating . Wooden floors are often glued to the subfloor if underfloor heating is used. The reason for this is that it creates less resistance for the warm-up time.

A wooden floor cannot be glued directly to a wooden floor with patterned floors such as chevron pattern floors and herringbone floors. An intermediate floor must be created that can absorb the stresses of a wooden floor. Get good advice from the supplier on this. A floor that is suitable for this is the Fermacell 2e22. In addition, a plank floor placed floating on a conductive foil. No intermediate floor needs to be created.

In addition to installing wooden floors, we also have experience with installing underfloor heating. Visit our showroom in Alphen aan den Rijn , Amsterdam or Naarden to discuss the options and obtain advice.

Points of attention for infrared / electric underfloor heating

  • Mainly floating installation of the wooden floor
  • Make sure that the subfloor is suitable for a wooden floor if the wooden floor needs to be glued
  • Power consumption is many times higher with electric underfloor heating
  • Be careful with signs and cutters in the floors because of the current

Installation method: electric underfloor heating in combination with a wooden floor

Follow the manufacturer's instructions for the installation method of the electric underfloor heating . After being professionally applied and covered with a mortar approved for wooden floors, the floor must be treated in the same way as a wet construction underfloor heating system .

  • Before you start gluing the wooden floors, you must carry out the firing protocol. As a rule, this protocol lasts 2 to 3 weeks and should only start after the floor is 28 days old.
  • The maximum residual moisture percentage in the floor may not exceed 2.0%.
  • Machine sand or brush the surface to remove any layers of slime. Then vacuum thoroughly with an industrial vacuum cleaner.
  • Prime the mortar with a primer, apply with a foam roller, lambskin roller or spatula. Consumption approx. 80-200 g/m². Drying time approx. 1 hour at 20 °C and max. 65% RH. Avoid puddle formation!
  • Then glue the wooden floor. Consumption approx. 1000-1200 g/m². Apply with B11 toothing.

Frequently Asked Questions

What is an electric underfloor heating system?

An electric underfloor heating system refers to a heating system where electric heating cables or mats are installed under the floor to provide heat.

What are the advantages of an electric underfloor heating system?

Some advantages of an electric underfloor heating system are:

  • Easy installation and no need for a hot spring. 
  • Flexibility in controlling the temperature in each individual room.
  • Fast response time and even heat distribution.
  • Suitable for both new construction and renovation projects.

What materials are needed for an electric underfloor heating system?

The materials needed for an electric underfloor heating system may include:

  • Electric heating cables or mats.
  • Installation accessories, such as mounting tape and mounting clips.
  • Insulating material (to limit heat loss downwards).
  • Floor finishing (such as tiles, laminate, wood or carpet).

Can an electric underfloor heating system be installed under any floor finish?

Yes, an electric underfloor heating system can be installed under most types of floor finishes, including tiles, laminate, wood and carpet. However, it is important to follow the manufacturer's specifications and guidelines to ensure that the floor finish is suitable for use with underfloor heating .

Do I need to take the floor height into account when installing an electric underfloor heating system?

In general, an electric underfloor heating system has a limited influence on the floor height, because the heating cables or mats are usually thin. However, it is advisable to check the system specifications to determine the overall floor height.

Can an electric underfloor heating system be used as the primary heating source in a room?

Yes, an electric underfloor heating system can be used as the primary heating source in a room, although these systems are often intended for smaller rooms such as the bathroom. It is therefore important to evaluate the heating needs of the room and ensure that the system can provide sufficient heat to meet expectations.

Is an electric underfloor heating system energy efficient?

Electric underfloor heating systems can be efficient in terms of energy consumption, but especially when combined with good insulation and solar panels. Without solar panels, power consumption will increase significantly.
