Our smart heating system

Why should you choose heating based on our Carbon Film? It has the highest number of advantages of all currently available technologies and it is suitable for most of applications.

It has an energy efficiency of 99 %. Its operation requires no maintenance and the consumption-related costs are considerably lower than with currently used technologies (by approximately 20 %). It has high variability of use due to its small thickness and undemanding installation (no boilers, heaters or pipes). Thanks to full area heating, fast start and precise regulation, the system provides you with maximum comfort. The Carbon Film neither stir up dust nor dry up air. It can be used as a primary or secondary source of heat. It is ideal in combination with photovoltaic panels and household batteries.

We install exclusively the latest model available on the market: our LARX CARBON-FILM.COM heating system. Its service life exceeds 30 years and our company offers it with a 10-year guarantee. It has by far the best price/performance ratio and it meets the most demanding requirements.

Ceiling heating system

The ceiling carbon films heat a ceiling board and change it into a full area heat source which evenly heats the room. The system does not have to heat the whole structure. It means that such heating is both effective and fast. Installation is easy and can be applied in so-called dry construction process which simplifies construction works. This heating system is suitable particularly for suspended ceilings made of plaster boards. Thermal insulation is fixed to the suspended ceiling and the heating film is applied directly under it, followed by a PE film and the ceiling board.
