"All Light And No Heat..." Why you should steer clear of 'ton bags' from your local tree surgeon.
Trees and branches cut by your local tree surgeon is basically free right? A waste product. You are doing the world a favour by burning it in your home? Well... not really. Sure its a waste product and its good for the environment that somebody should make use of it. Just do yourself a favour, don't let that someone be you.
Preparing firewood is labour intesive. It takes time to split and cleave the wood and stack it for drying for up to two years. If pressed tree surgeons will say its the customers job to season their wood. Do you store your wood in a dry shed for two years? When wood crackles and spits as it burns it may as well have been cut yesterday. The wood isn't burning efficiently. Most of its energy is used boiling off water and going up the spout making your stove, flue and the outside word sooty in the process.
In purpose farmed, managed forests the process of splitting and stacking is mechanised and the seasoning takes place in low temperature kilns which use dehumidifiers as much as heat to draw out moisture resulting in a product that delivers over 3 times the energy to your home than badly seasoned wood. You will be amazed at how little you need and how long it lasts.
Also lets look at the maths of the 'ton bags'. That's just an expression to mean a 1 cubic meter bag. It may weigh a tonne if filled with with wet builders' sand but filled with wet logs it is more like 250kg. And these are loose packed. Our close packed logs fit twice as much in the same volume. So 1m3 from us is equivalent to 2 ton bags. We can guarantee that calorie for calorie our properly prepared wood is cheaper than anything you will get from a tree surgeon.
Our fire wood is a waste by product of the timber industry and comes from sustainable, managed forests. As growing trees capture 100% of the carbon they later release when burned they are considered a green carbon neutral alternative for domestic heating.
|Common Name||Botanical Name||Comments|
|Alder||Alnus||Poor quality firewood. Poor|
|Apple||Malus||Needs to be well seasoned. Burns well with a pleasant smell and no sparking or spitting. Good|
|Ash||Fraxinus||One of the best firewoods. It has a low water content and is easily split with an axe. Burns best when seasoned but can be burned green. Excellent|
|Beech||Fagus||Beech has a high water content and will therefore only burn when seasoned. Good|
|Birch||Betula||An excellent firewood that will burn when green. However, it burns quickly so should be mixed with a slower burning wood such as Oak. Very Good|
|Cedar||Cedrus||A good firewood which burns with a pleasant smell. Gives a good lasting heat and does not spit much. Small pieces may be burned green. Quite Good|
|Cherry||Prunus||Must be well seasoned. Burns with a pleasant smell without spitting. Quite Good|
|Elm||Ulmus||A good firewood but due to its high water content of approximately 140% (more water than wood!) it must be seasoned very well. It may need assistance from another faster burning wood such as Birch to keep it burning well. However it gives off a good, lasting heat and burns very slowly. Larger pieces of wood will prove difficult to split. Quite Good|
|Eucalyptus||Eucalyptus||Allow to season well since the wood is very sappy when fresh. Can be difficult to split due to stringy wood fibre. Best method is to slice into rings and allow to season during the summer, the rings will start to split themselves. Burns fast with a pleasant smell and without spitting. Quite Good|
