Warm up to many advantages. 

ETHERMA, based in Henndorf am Wallersee (Salzburg), is one of the first providers of electric underfloor and infrared heating panels. The many advantages of our heating systems are obvious. 

Pleasant WARMTH.
Just as you like.

Nobody has to live without underfloor heating.

Anyone who has not previously had underfloor heating can fulfill this dream easily and cost-effectively as part of a renovation project. With a maximum mat thickness of 4 mm, ETHERMA’s electric underfloor heating systems can also be retrofitted very easily under any floor covering.

This does not require any time-consuming demolition work and our underfloor heating systems are also possible where there is no pipework in the screed. Precise individual room control also saves on running operating costs.


Advantages of ETHERMA underfloor heating systems:

  • Up to 50 % lower investment costs than with water-based underfloor heating systems

  • Quick and easy installation thanks to low installation height (max. 4 mm)

  • For any floor covering: tiles, laminate, parquet, stone and much more.

  • Customized on request

  • Operating cost savings through targeted individual room control

  • Over 25 years of service life, without any maintenance


More than just hot air – cozy warmth with infrared.

Real infrared heating panels do not heat the air (convection), but people and objects in the room. These absorb the heat and emit it evenly. This creates a pleasant feeling of comfort. Without circulating air currents and without stirring up dust – ideal for allergy sufferers.

Installation is inexpensive, quick and dirt-free. All you need is a power connection. Infrared heating panels from ETHERMA are also extremely durable, absolutely maintenance-free and without heat loss.

Advantages of ETHERMA infrared heating panels:
  • Up to 50 % lower investment costs than with conventional heating systems

  • Easy mounting on the wall or ceiling

  • Heat immediately noticeable (< 10 min)

  • Pleasant room climate thanks to infrared heat

  • Safe against breakage and overheating

  • Long-lasting and maintenance-free

What enthusiastic CUSTOMERS say about ETHERMA.

Family Schinnerl, Austria

This house was raised by one storey. As screed was not possible due to the structural design, ETHERMA mesh heating mats were the best option. Mats with a low voltage of 24 V were used in the bathroom. They even provide cozy warmth in the barrier-free shower and on the step of the bathtub entrance.


„ETHERMA has exceeded our expectations. The new heating system delivers what it promises. Especially in terms of low operating costs. A convenient system without maintenance costs or annual servicing.“

Mag. Marietta Kiesling, Vienna

During the renovation of the “Salon Mignon”, an old apartment in the 18th district, the radiators and gas boiler were replaced by efficient electric underfloor heating from ETHERMA. The choice fell on a mesh heating mat for the parquet floor, but also for the bathroom and WC. It is only 2.7 mm high and can be trowelled into the flexible adhesive. Around 50 m² of heating mats were laid over the entire surface.


„The heating system is particularly responsive thanks to the close-to-surface installation. A highly convenient and cost-effective solution for all rooms, especially in older buildings.“
