I have heard mixed reviews about eucalyptus firewood. Some people love it and others don’t like it so much. It has a very high BTU and eucalyptus oil is highly flammable. I don’t have any experience burning eucalyptus, but many people claim that it burns long and hot, producing nice coals and low ash. But then there are others who claim that it burns too hot and too fast and doesn’t last long. This may be due to different varieties, or maybe more likely just pure BS. Eucalyptus is a very popular wood for firewood in many parts of the world, so I wouldn’t hesitate to burn it if I had it.
Most varieties of eucalyptus trees come from Australia and a few come from New Guinea, Indonesia and surrounding areas. They have been introduced into many parts of the world including California, where they are often used for firewood. California timber companies have experimented with eucalyptus plantations, but so far there hasn’t been much commercial interest in the wood in the USA, other than for firewood.
Eucalyptus is a hardwood, and one of the fastest growing trees in the world. It has a twisted grain and should be split when green, since it gets tough as it dries. It is also claimed that eucalyptus can take longer to dry than many other types of wood, up to two years. That claim also triggers suspicion in my BS-ometer.
Eucalyptus oil comes from distilling the leaves and has many uses. It can be used as insect repellent, antiseptic, flavouring, fragrance and has medicinal, therapeutic and industrial uses.
