The calorific value of the fire wood is closely connected to the moisture level of the
firewood. Moist firewood has a low heat value. The more water the wood contains the
more energy it takes this water to vaporize resulting in energy is being lost.
6.1.2 Drying and storage
Drying wood takes time. Proper air drying takes approx. 2 years.
Here some tips:
Store the wood sawn, split and stacked in an airy, sunny place, which is protected
against rain.
Store firewood stacks at a hand’s breadth apart as this ensures that the air flowing
through takes the moisture with it.
It is a good idea to bring the firewood into the house 2 – 3 days before you need it.
6.1.3 Room ventilation and stoves
If there is an extractor fan in the same room as the bionic fire please make sure that the
bionic fire is not closer than 2 meter to the extractor fan.
The stove requires a permanent and adequate air supply in order for it to operate safely and
efficiently.
In accordance with the current building regulation the installer may have fitted a permanent
air supply vent into the room in which the stove is installed to provide combustion air. This
air vents should not under any circumstance be shut off or sealed.
6.2 Stove functioning

The upper combustion chamber
(UCC)
