We recommend using chopped birch- or beechwood that has been stored outside under a roof for at least 1 year. Wood that has been stored inside tends to become to dry and burn up fast.
It is best to chop the wood in the winter when the moisture level is low. Chop the wood in pieces of approx. 10 cm in “diameter”. The length of the wood log depends on the size of the combustion chamber in the stove. Most new wood burning stoves have a 33-40 cm wide combustion chamber.
To achieve the best burning the moist in the wood must not be more than 18%, which can be achieved by storing the wood outside under a roof for 1 year. To measure the moisture in the wood, you can use a moisture meter. You can also put dishwasher liquid on one end of the wood and blow in the other end - if soap bubbles occur then the wood is dry and ready to use. Follow this guide.
