The thinnest and lightest panel heating

October 2020

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

Papers with different carbon contents displayed different electrical resistances.

General investigations show that the electrical conductivity values change due to minimal changes in carbon content. During industrial carbon fibre paper production, this phenomenon requires an extremely precise dosing and controlled carbon fibre dispersion.

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 the 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 and 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 is. There are countless possible uses in the area of heat dissipation for simple implementation in buildings, but also in hard-to-reach places or with complex shapes.

Its practical application is characterized by the extremely small need for space, 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 saving of energy. With a temperature increase of 35-50°C, an electrical performance of 150-180 W/m² is required. The carbon paper is compatible with its own photovoltaic system in combination with electricity storage. This enables a high degree of independence possible.

For those who suffer allergies, there is a positive health aspect in that there is minimal dust circulation within the room. This is achieved through radiant heat (no convection) compared to conventional heating. The patented carbon paper is used to combat mould growth, in which the dew point is displaced by separate temperature controls between 16-20 ° C.

The advantage of this system results through the even, flat electrical current distribution, dimensional stability. Possible applications such as ceiling, wall and floor heating, caravan and mobile home floor heating, desk and table heating, etc. stay within the low voltage range of between 12 to 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.

Accordance with the Sustainability Concept

Radiant heat, with a high radiation density (no convection heat), provides for even heating of objects and provides 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 fulfils the concept of sustainability.
