Various options for distributing hot air and optional fan
The fan improves the circulation of hot air in the room and makes the temperature constant.

Lack principle:
For more pleasant heating thanks to uniformly distributed temperatures, we recommend applying the following principle :
A fan (fitted under the stove for example) sucks in room air via a network of ducts in the furthest parts of the room or neighbouring rooms preventing the gathering of thick dust on the ground.  A depression is created and consequently a return of heated air through carefully positioned openings.
