If you have an open fireplace, a wood-burning stove or a log burner at your Surrey property, you’ll need to stock up on firewood for those colder winter months. At LJN Firewood, we supply quality products, such as kiln-dried logs, seasoned logs, hardwood logs, and kindling, to suit your wood-burning needs. If you’re unsure about which type of wood to choose for heating your Cranleigh, Dorking, Godalming or Guildford home, this page explains everything. We also have a page that explains our delivery options and pricing.
There are many different types of wood, each with its own distinct calorific value. This relates to the amount of energy inside. To determine the level of heat that wood gives off when burned and at what rate, we use a unit of measurement called the British Thermal Unit (BTU).
A green tree has a moisture content of around 70% to 100%, which means the wood will burn poorly, create lots of smoke and have a low BTU value. Ideally, this wood should have a moisture content of somewhere between 10% to 25%. This ensures a clean, efficient burn with a high BTU value.
While there are many varieties of natural firewood, we can categorise them into either hardwood or softwood. Hardwood is denser than softwood, so it contains more energy pound-for-pound. This results in a higher BTU value and also means that hardwood logs will burn hotter, and for much longer, than a typical softwood alternative.
Although you can use softwood for wood-burning stoves and fireplaces in Cranleigh, log burners in Godalming and even wood-fired pizza ovens in Guildford and Dorking, it will require more logs to sustain the same heat and an equivalent burn duration as that produced by hardwood logs.
Softwood’s main benefits are that it’s easy to light and delivers an intense but short burst of heat, perfect for igniting hardwood fires. At LJN, we only use virgin softwood for kindling purposes, ensuring the best quality. This also eliminates debris in your ash, such as nails or paint, that often occurs with other, lower-grade kindling.
Drying wood before use makes it more efficient. Not only will green wood give off less heat, but it will also create more tar and creosote deposits. This can lead to chimney fires. Seasoning logs by leaving them to air dry naturally, for at least a full year, reduces the moisture content to somewhere below 30% and this is what most log sales companies target.
Another drying process is kiln drying logs. For this, we use a kiln drier to produce professional-quality kiln-dried logs. This involves forcing the water out of the wood through sustained airflow and regulated temperature control. The result is a moisture content between 10% and 20%.
We have invested over £350,000 into the firewood production side of our business alone to ensure a constant supply of clean, low-moisture, hot-burning and easy-to-light wood. Our wood is suitable for a wide range of wood-burning appliances. We supply and deliver to customers in:
We can cut and dry special sizes of wood and make these to order, with an approximate lead time of 1 to 3 weeks. Please contact us for prices on our special size services across Surrey.
