Key features of LARX carbon heating Films

LARX carbon Films provide electric heating and operate on the basis of the proven resistance method of heat production. From the point of view of the physical principle, this method of heating is 99% efficient. Carbon heating Films provide Local heating – it produces heat directly and only in the room where it is needed (savings). The strips of carbon heating Films are connected in parallel by a brown and a blue wire.

The heating system is usually designed with a separate circuit and thermostat for each room. The switching element of the thermostat is a power relay, so the control is performed 0/1 (off or on). The thermostat must be designed for electric underfloor heating and must have a protective floor temperature sensor.

Carbon heating Films are very thin, with almost no impact on floor depth. Installation over the entire surface of the room guarantees heating across the whole floor. We do not recommend large gaps between the individual strips of Film; they cause uncomfortable temperature differences. Films should not be installed under built-in furniture and fixtures. We recommend installing them under other furniture; the furniture should then have legs of at least 5 cm.

Design notes

Design procedure

  • 1. Choice of installation method - under screed, floorboards or directly under a floor covering
  • 2. Calculation of heat loss for each room
  • 3. Preparation of the laying plan, including positions of thermostats
  • 4. Proposal of the output of carbon heating Films - division into circuits, possible strengthening of circuits in large rooms
  • 5. Calculation of control resistances - after installation, we recommend measuring the resistance of each circuit and comparing it with the calculation, as well as checking the heating function using a thermal imager.
  • 6. Design of switchboard mounting, dimensions of main circuit breaker and other elements
