Chronology of Wood Heat
|Updated on April 28, 2014.|
This chronology was drawn from various sources and tends to focus on European dates
and then switches to a chronology in the United States. It does not attempt to cover
important dates in Russia, Japan and many other countries. If you think we have omitted
important milestones, especially in the last 30 years, please send them to us at
