LARX carbon heating Film technology

  • Simplicity of technology
  • Low acquisition costs
  • Fast realization process
  • Maintenance-free comfortable system
  • No space demands
  • Smart control of every room, including home security

The LARX CARBON-FILM.COM system is a modern way of heating with electricity for residential and industrial constructions. Carbon heating Films provide maintenance-free heating that operates on the simple and proven principle of converting electrical energy into heat. They provide comfortable underfloor heating without water, without a boiler and technical facilities. By placing carbon heating Films over the entire surface, the heat distribution across the floor is much more even than with conventional hot water pipe or cable systems. The main advantage of the system is that the investment costs are manageable.
