Yesterday evening's seminar by Catriona Ross was an excellent look at wood fuel installations in the Cairngorms National Park.  It raised some interesting discussion on wood fuel supply, moisture content and the performance variations of different wood types.  It's all really important when it comes to the overall performance of a biomass boiler of log burning stove and sharing the thoughts of those present was very useful.  I think that for the time being, anyone considering a biomass based heating solution needs to be aware that they need to take a large responsibility for the quality of the fuel they use, until they have developed a good relationship with a trusted supplier.  And there is an important role for training and informing people about the main aspects of woodfuel supply and storage.
