If you have a wood-burning stove, open fireplace or log burner at your property in Cobham, Guildford or the wider Surrey and West Sussex regions, then you’ll need to stock up on firewood for those cold winter months. At LJN Firewood, we supply such products as kiln dried logs, firelighters, seasoned logs, hardwood logs and kindling to suit your wood burning needs.
If you’re unsure about what type of firewood to choose to heat your home in Cobham, Cranleigh, Godalming, Guildford or Weybridge, this page details everything you need to know about firewood.
There are many different types of firewood, each of which have its own distinct calorific value, which relates to the amount of energy inside. To determine the level of heat wood gives off when burned and at what rate, we use a unit of measurement called British Thermal Unit (BTU).
A green tree has a moisture content of around 70%-100%, which means the wood will burn poorly, create lots of smoke and have a low BTU value. Ideally, firewood should have a moisture content of somewhere between 10%-25% to ensure a clean, efficient burn with a high BTU value.
While there are many varieties of natural firewood, we can categorise them into either hardwoods or softwoods. Hardwoods are denser than softwoods, which means that pound for pound they contain more energy. This results in a higher BTU value and means that hardwood logs will burn hotter and for longer than softwood alternatives.
Although you can use softwoods as firewood for wood-burning stoves in Cobham, fireplaces in Cranleigh, log burners in Godalming, wood-fired pizza ovens in Guildford and campfires in Weybridge, it will require more logs to sustain the same heat and burn duration produced by hardwood logs.
Softwoods, however, are easy to light and therefore make excellent kindling and firelighters.
Drying firewood 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, which 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%.
Another drying process uses a kiln drier to produce kiln dried logs, which involves forcing the water out of the wood through sustained airflow and regulated temperature control. The result is a firewood with somewhere between 10% and 20% moisture content.
We have invested over £350,000 on the firewood production side of our business alone, to ensure the production of clean, low moisture, hot burning and easy to light firewood, suitable for a range of wood-burning appliances. We supply and deliver to customers throughout the South East, as well as offering a stacking service for your convenience.
