The panel heating made of paper.

KOHPA®therm is the lightest and thinnest panel heating in the world.

  • 0,20 mm Natural fibres and recycled carbon fibres. Nothing else.

  • 24 % energy savings compared to conventional heating systems. Thus pioneering for the energy turnaround.

  • 99 % Recycled material


With a material thickness of only 0.20 mm, the lightest and thinnest panel heating available on the market consists of a mixture of natural fibre and recycled carbon fibres. In addition to its good formability, the patented material is breathable, dimensionally stable and easy to process. KOHPA® therm is characterised by the specially developed contact strips (contacting). Voltage in the low-voltage range (24-42 V) can be applied to the contacts by qualified personnel. KOHPA® therm may only be used as a surface heating in combination with the original contacting. With energy savings of up to 24 % compared to conventional heating systems, this product is groundbreaking for the energy turnaround.

Frequently asked questions

  • What does KOHPA® mean?

    The name comes from the German words KOH for carbon fibre and PA for paper.

  • What is the material made of?

    Made of natural and carbon fibres.

  • Why is the paper electrically conductive?

    Carbon fibres are electrically conductive.

  • How is KOHPA® produced?

    On a conventional type of paper machine.

  • How does electricity get into the paper?

    Conductive contact strips for plus and minus pole are applied to the edges of KOHPA® therm.

    Note: KOHPA® therm may only be used as surface heating in combination with the original contacting.

  • Then how does the electricity get in there?

    The poles are connected to a transformer or switching network in a technically correct manner.

  • What voltage can be fed in?

    24 V to 42 V in the non-hazardous low-voltage range (DC voltage).

  • How is the heat generated then?

    The electrons of the electric current reach the carbon fibres via the contact strips on the sides. So it gets warm in a matter of seconds.

  • What surface temperature can be achieved?

    Infrared heat of 35 °C is achieved - this means about 15 °C above room temperature.

  • What is infrared heating?

    The heat coming from KOHPA® therm can be compared to the heat of the sun's rays.

  • What lead time does the heating need until the heat is noticeable?


  • How does KOHPA® therm perform compared to conventional heating?

    KOHPA® therm as infrared heating creates a feel-good climate, which achieves the same effect as convection heating at a 2-3°C lower room temperature. A reduction of 1°C in room temperature saves 6% in heating costs.

  • What is the overall cost structure compared to conventional heating?

    Low investment costs, no maintenance costs, no wear and tear, no holding of resources.

  • How high is the energy consumption?

    The surface power is 150 W/m²

  • Can KOHPA® therm be used together with a photovoltaic system?

    Yes! KOHPA® therm is powered by electricity. This makes self-sufficient heating possible.

  • What is the advantage for house dust allergy sufferers during heating with KOHPA® therm?

    Compared to conventional radiators, KOHPA® therm does not create any dust turbulence.

  • How is KOHPA® therm installed?

    KOHPA® therm can only be installed by qualified personnel.
