3.2 HOW TO PREPARE OR BUY GOOD FIREWOOD

3.2.1 WHAT IS GOOD FIREWOOD?

Good firewood has been cut to the correct length for the wood fire, split to a range of sizes and
stacked in the open until its moisture content is reduced to 15 to 20 per cent.

3.2.2 TREE SPECIES

The tree species the firewood is produced from is less important than its moisture content. The
main difference in firewood from various tree species is the density of the wood. Hardwoods such
as gums, Manuka or ironbark are denser than softwoods. Hard wood will produce long-lasting coal
beds combined to more heat and longer burn cycles.
Old, leaky cast iron wood fires wouldn't hold a fire overnight unless they were fed large pieces of
hardwood. That is no longer true. You can successfully heat your home by using less wood and
give the forest a break at the same time.

3.2.3 LOG LENGTH

Logs should be cut about 25 mm shorter than
the firebox so they fit in easily. Pieces that are
slightly too long make loading the wood fire
very difficult. The most common standard
length of firewood is 400 mm.
The pieces should be a consistent length, with a
maximum of 25 mm variation from piece to
piece.

3.2.4 PIECE SIZE

Firewood dries more quickly when it is split. Large unsplit rounds can take years to dry enough to
burn. Even when dried, unsplit logs are difficult to ignite because they don't have the sharp edges
where the flames first catch. Logs as small as 75 mm should be split to encourage drying.
