THE ELECTRIC UNDERFLOOR HEATING

THE ELECTRIC UNDERFLOOR HEATING

THE COMFORT OF HEATING.

We want you to feel comfortable with your heating. Because the choice of heating system will affect your life. In addition to efficiency, comfort should not be neglected. Electric underfloor heating meets both criteria.

Electric underfloor heating works in the same way as water-based underfloor heating. The difference is that the floor is heated with electricity and not with hot water. The electric underfloor heating ensures a pleasant level of comfort and warms the room with radiant heat from below. The heating elements are either placed under the floor covering or laid in the screed. ETHERMA offers three types of electric underfloor heating for different floor coverings.

HEATING MATS

This is a mesh where heating cables are processed on the mat. The heating mat is very thin at 2.7 mm. The mesh heating mats are available in different lengths and with different outputs. They are ideal for use in the bathroom or in damp rooms under the tiles or even under a bonded PVC floor in the leveling.

HEATING FOIL

ETHERMA heating foils are heating mats made from reinforced aluminum fabric. This type of electric underfloor heating is laid "floating". This means that the electric underfloor heating is laid separately under the laminate or parquet floor without being filled in. This is possible because the heating mat is only 1.3 mm thick.

HEATING CABLE

The heating cable is an electric underfloor heating system used in the screed. This heating cable is available in different lengths and with different outputs. Milling also allows the heating cable to be used in an existing situation.

HOW DOES ELECTRIC UNDERFLOOR HEATING WORK?

Electric underfloor heating consists of either heating mats or heating cables. The heating mats are thin mats with a thickness of 1.3 to 3.3 mm. An electrical cable is attached to these heating mats. Current flows through this cable. The power cables have a high resistance. This heats up the heating cables. The heat is transferred to the floor above. This gives the floor a comfortable temperature. As the floor heats up, the room also heats up. A heating cable is used in the screed. This works just like a heating mat.

THE PROS AND CONS OF ELECTRIC UNDERFLOOR HEATING

The areas of application of the ETHERMA underfloor heating range from temperature control and heating of cold floors and rooms to special heating of all kinds. The electric underfloor heating has many advantages.

Below are the advantages at a glance:

  • Can be used in any situation

    Is installed quickly and easily

    Ensures fast heat-up time and short response time

    Is invisible

    Controlled per room

    Generates healthy heat

    Is perfect in combination with solar panels

    Is maintenance free

    Impresses with its low acquisition costs


Electric underfloor heating has more advantages than disadvantages. However, there are a few things to consider:

  • Electric underfloor heating consumes more than a heat pump.

    Electric underfloor heating is less suitable as main heating in poorly insulated situations.

    Cooling is not possible with electric underfloor heating.

DIRECT OR STORED - YOU DECIDE!

A distinction is made between direct floor heating and partial storage heating. The difference between direct heating and partial storage heating lies in the installation depth of the heating elements. With direct heating, installation is carried out close to the floor, while partial storage heating uses the screed as a storage medium. With partial storage heating, the floor is heated up - mostly overnight - and thus gives off pleasant warmth throughout the day. Depending on the electricity tariff and individual requirements, our ETHERMA planning team will help to find the right heating solution for you.

UNBEATABLE TOTAL COST.

For many years, it has been assumed that heating with electricity is expensive. In this case, people are usually thinking of obsolete storage heaters. But those are now history. Thanks to technical developments, precise control as well as structural optimisation in the insulation of outer walls and windows, this is no longer true.

On the contrary - if you take into account the investment in the heating system, operating costs and the necessary maintenance over 20 years, electrical heating, either as underfloor heating or in combination with LAVA® infrared heating, represent one of the most comfortable and cost-effective systems available when compared to other heating systems.

THE TAILOR-MADE NET HEATING MAT.

ETHERMA is one of the few manufacturers in Europe to offer the heating mats individually made to measure - this makes installation easier and always fits perfectly, even with unusual architecture. The made-to-measure mesh heating mat is the ideal solution, especially in bathrooms and wellness areas. For example, for heated loungers, benches, steam showers and shower trays.

But any other special laying geometry can also be perfectly heated with the mesh heating mat.

ONE FOR ALL OCCASIONS

Other special heating mats are the extremely resistant ETHERMA NST, which is used in particular in public areas and swimming pools and wherever aggressive cleaning agents are used. But also when used as open space heating under slabs and thin coverings.

At the same time, the robust NST heating mat is suitable as a wall heater - on the one hand to isolate the cold and on the other hand as a room heater with pleasant radiant heat. As a positive side effect, it prevents damp walls.

FREQUENTLY ASKED QUESTIONS

Can I install electric underfloor heating myself?

Yes, this is partially possible. It is possible to do the preparation and laying yourself, but the electrical connections must be carried out by a qualified professional. See our assembly instructions for this.

 

Can I cut electric underfloor heating?

Yes, it is possible to cut the heating mat or the net. Most heating mats have a standard width of 50 cm and a specific length. You must cut the mesh of the mat during installation and fold the mat over to cover the entire room with electric underfloor heating. ATTENTION: The heating cable must not be severed - only the mesh may be cut. Otherwise the heating mat is defective.

 

What is the lifespan of electric underfloor heating?

The average lifespan of electric underfloor heating is more than 30 years. Think of the electrical installation in your home - these power lines also last for several decades. The same applies to the heating conductors of ETHERMA's underfloor heating. In addition, electric underfloor heating is maintenance and service-free.

 

How many m² of electric underfloor heating should I order?

Example: The gross area of a room is 5.0 x 5.0 mtr = 25.0 m². We calculate with a laying of 80 - 85% of the area. 25.0 m² x 80% = 20.0 m² underfloor heating.

 

Which service should I choose?

  • 90 W/m² - comfort heating of the floor or main heating in the energy-saving house.

  • 130 W/m² - comfort heating of the floor or main heating in the energy-saving house.

  • 160 W/m² - As main heating in rooms with standard insulation.

  • 200 W/m² - For heating rooms with little or no insulation.

 

Do I have to control electric underfloor heating with a thermostat?

Yes, electric underfloor heating must be controlled with a thermostat.
