WHICH KINDS OF WOOD ARE SUITABLE FOR wood fires OR stoves?
Birch, ash and beech are extremely suitable kinds of wood for wood fire inserts or wood stoves. Oak can also be used, but this often needs be dried for longer. However, the wood that you use must not have been treated, painted or varnished, because this releases harmful substances during burning.
Once you have chosen a kind of wood, it is important to select the right length and thickness for your logs. A common length is 25, 33 or 50 cm. As far as the thickness is concerned, it is important that the blocks are not too thick because a large mass is more difficult to keep lit.
Please note that a lot of wood is too wet to burn. You can check how suitable your wood is with a hygrometer; a moisture percentage between 16% and 20% is ideal.
