Drying and storage

Drying wood takes time: proper air drying takes approx. 2 years.

Here are some tips:

• Store the wood sawn, split and stacked in an airy, sunny place, which is protected

against rain (the south side of the house is particularly suitable).

• Store the ﬁrewood stacks at a hand’s breadth apart, as this ensures that the air ﬂow-

ing through takes the moisture with it.

• Avoid covering the ﬁrewood stacks with plastic, as this prevents the moisture from

escaping.

• It is a good idea to bring the ﬁrewood into the house 2-3 days before you need it.

Room ventilation and stoves

There must not be an extractor fan ﬁtted in the same room as the stove as this can cause

the stove to emit smoke and fumes into the room.

The stove requires a permanent and adequate air supply in order for it to operate safely

and efﬁciently.

In accordance with current Building Regulations 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 vent should not under any circumstances be shut off or sealed.

ONLY USE RECOMMENDED FUELS

The following table shows the caloriﬁc value of different types of wood, which have been

stored for 2 years, and which have a residual moisture of 15-17%.

Wood Kg dry wood pr. m

compared to beech/oak

Hornbeam 640 110%

Beech and oak 580 100%

Ash 570 98%

Maple 540 93%

Birch 510 88%

Mountain pine 480 83%

Fir 390 67%

Poplar 380 65%

1 kg of wood yields the same heat energy irrespective of wood type. 1 kg beech merely

takes up less space than 1 kg of ﬁr.
