Principles of Combustion
All fuels need the presence of oxygen to burn. The more oxygen a fire gets the hotter
and faster it will burn. When, where and how air is introduced into a firebox of a stove
will greatly influence the heat output, burning rate, fuel efficiency and impact on the
environment.
WOOD AS FUEL
Wood is an entirely renewable resource but needs to be sourced, stored and used
carefully. Wood needs to be seasoned (cut and stored for at least one year after
cutting) or kiln dried prior to burning in the stove with a moisture content of less
that 25%. As a fuel it gives a good flame and a reasonably high heat output, the burn
rate is high but will vary considerably depending on size and species. Wood requires
combustion air to be directed down onto it to burn most efficiently.
TIPS FOR IDENTIFYING DRY WOOD
1) Visible cracks at the end of the log
2) Bang two logs together, they will sound hollow
3) Wood moisture content measuring devices are available
It is important to burn wood in complete loads, this will ensure all the wood in the
load is at the same stage of combustion as much as possible. By doing this the firebox
temperature will stay in the gas burning stage for longer, making the stove more
efficient and cleaner burning.
We do not advise you to try and keep a wood fire in overnight. When the air control
is put on a low setting, logs can smoulder and burn inefficiently, releasing harmful
emissions into the atmosphere.
