Room heating : FAQ

Find here all our tips related to your room heating appliances

We recommend that you allow for appliances with 100 W/m² (e.g. for a 15 m² bedroom, 1500 W will be sufficient). However, if the building is insufficiently insulated, this value will not be enough. In France or Scandinavia, the value can drop to 55 W/m² for new housing (accounting for the insulation quality of the building and specific calculations carried out by a specialised engineering firm).

Programme your heating appliances and ensure that your home has a good level of heat insulation. You should preferably use electronic appliances whose accuracy will enable you to obtain a lower temperature setting.

Avoid positioning heating appliances near doors, windows, etc. To improve heat distribution and prevent one part of the room from being cold and the other hot, it is better to have two 1000 W heating appliances in the room rather than a single appliance of 2000 W.

Check whether the electrical current is reaching the appliance (NB: this operation requires that all possible safety measures relating to the use of an electrical current are taken) and whether the (mechanical) on/off switch or the (electronic) cursor mode is not set to off.

Check that the room temperature is not too high for the appliance to work. Set the temperature to maximum to see whether the appliance starts heating after a few minutes; then return to the required setting. NB: for an electronic appliance, the appliance operates intermittently over a period of 40 seconds according to requirements.
Check the operating mode position on electronic appliances (Comfort/Economy, Frost-free, Stop, Program settings). Move the cursor to comfort mode to check whether the appliance heats up; the malfunction may come from the programming if you are in Program mode.
The sensor may be faulty on the electronic appliances: Switch the heating off then on again. If the heating LED flashes continuously, the sensor is damaged. Contact the after-sales service or your dealer to replace it if your appliance is under warranty.

Check that:

  • the appliance is not in a draught 
  • the temperature setting has not been changed or set to maximum
  • the appliance is to small to heat the room

On electronic appliances, there may be an unexpected event on the grid. In the event of a problem (blocked thermostat, etc.), cut off the power supply to the appliance (fuse, circuit breaker) for 10 minutes, then switch it back on. If this situation occurs frequently, get your electricity provider to check the power supply.

  1. Increase the temperature setting
  2. Check whether the output of your appliance is suited to the size of your room (see the section on power settings)
  3. On an electronic appliance, if the heating LED is flashing continuously (slow flashing every 2 seconds), the measurement sensor is damaged

Otherwise, carry out the following checks:

  • Check whether there is another heating mode in the room
  • Make sure that your appliance is heating only the room (and not the entire house)
  • Check the power supply voltage of the appliance (our appliances have a power calculated for 230 V).

It should be installed at a minimum 120 mm from the floor to leave room for air intake and ensure the least amount of disruption due to air movement. The securing bracket provided with the appliance ensures that the appliance is correctly positioned.
