The thinnest and lightest panel heating

October 2020

Based on many years of research and industrial production of carbon fibre papers with different carbon contents, it was necessary to find a measure regarding the electrical reactions that would enable the project to produce a panel heating system that would meet the requirements of practical conditions.

Papers with different carbon contents had different electrical resistances.

The overall investigations show that the electrical conductance values change due to the smallest changes in carbon content. During industrial carbon fibre paper production, this phenomenon requires extremely precise dosing and controlled dispersion of the carbon fibres.

Panel heating

According to all research results it was possible to develop a calculation program with which the conditions for special operations can be determined and variations calculated. Only secondary carbon fibres are used. In the course of electromobility, this paper will have a future, since the area-related heating output requires less electricity than the previously used ones.

The thinnest an lightest panel heating made of electrically conductive paper

The novelty of this electrically conductive carbon paper, with a weight per unit area of only 75-100 g / m² and an extremely small thickness of 0.20-0.25 mm, represents the thinnest and lightest panel heating. There are countless possible uses in the area of heat dissipation for simple applications in buildings, but also in hard-to-reach places or with complex shapes.

The practical application is characterized by the extremely small space requirement, good formability and absolute dimensional stability. This results in low investment costs.

Compared to conventional heating systems, the economic efficiency is shown positively by the achieved radiant heat and radiation density. Heating costs are reduced, which means energy saving. With a temperature increase of 35-50 °C an electrical power of 150-180 W/m² is required. The carbon paper is compatible with its own photovoltaic system in combination with electricity storage, which enables a high degree of independence to be achieved.

The allergy sufferer has a positive health aspect in that there is minimal dust circulation in the room through radiant heat (no convection) compared to conventional heating. The patented carbon paper is used to combat mold growth, in which the dew point is displaced by a separate temperature control between 16-20 ° C.

The advantage of this system results from the even, flat electrical current distribution, dimensional stability and possible applications such as ceiling, wall and floor heating, caravan and mobile home floor heating, desk and table heating, etc. in the low voltage range between 12 and 48 V.

If the paper is damaged by holes or tears, the current conduction does not suffer and the proportional distribution is maintained.

The carbon paper can be made waterproof. Wet deformation, different degrees of absorbency as well as specific air permeability values can be adjusted according to appropriate requirements.

The material can be treated and processed like normal paper, but with absolute dimensional stability.

Following the sustainability concept

Radiant heat with a high radiation density (no convection heat) provides for even heating of objects and you get a natural comfortable climate (tiled stove effect).

 Higher efficiency due to lower surface temperatures (radiant heat 38°C) than convection heat (radiators 55°C).

 In addition, the use of secondary carbon fibres fulfills the concept of sustainability.
