Closed combustion

Scan stoves objective is to develop wood-burning stoves that burn more cleanly and more economically than all others. You can therefore enjoy the fire from your Scan stove with a clear conscience. Read more about combustion here.


There are two forms of air supply:

  1. Air that is fed into the room from outside
  2. External combustion air that is fed directly into the combustion chamber (closed combustion)

Instead of opening a window and risking the cold and draughts, you can feed air directly into the room from outside via a fresh air branch pipe. Doing this replaces the air that has been used during combustion. The branch pipe can be fitted to the back of the stove or as a box under the combustion chamber.

Most Scan models can be equipped with this form of fresh air supply, also after the installation.

In well-insulated houses it can be a good idea to feed air directly into the combustion chamber from outside, in other words closed combustion. This is especially important in houses with mechanical ventilation or cooker hoods close to the place of installation.

Most Scan models can be equipped with an external air supply, either at the rear of the stove or in the bottom. Most models are already prepared for closed combustion from the factory, while on others you must order it as an extra accessory.


Clean combustion means that the stove has a double combustion system that converts up to 90% of the flue gases and smoke particles into heat. This minimizes the smoke emission, because the stove uses the energy to generate heat instead of smoke. 


The highly developed combustion system, Clean Burn, ensures that our wood-burning stoves are technological forerunners and set new standards for high efficiency and low CO2 emissions and wood consumption. Below you can see an example of how the Clean Burn combustion system with double air deflector system works on one of our models.
