Research from Technologie- und Förderzentrum in Germany* shows that new wood burning stoves burn more cleanly than older wood burning stoves. Tests have been made on wood burning stoves that are controlled both manually and automatically.
The insitute has measured the level of particle emissions from wood burning stoves from 1980 and until 2000. The result is very positive for the environment.
Cause:
Wood burning stove producers have become very good at developing technology and automatic control devices which make for easier control, less use of firewood and eco-friendly combustion.
When you fire with firewood you are choosing a carbon neutral source of heating, and you’re doing both yourself, your neighbours and the environment a big favour by replacing your old wood burning stove with a new one which will save the environment from much particle pollution and tar.
