FAQs
What are the logs made of?
Strogs are made from chopped and then compressed straw. This straw is a by-product of wheat, barley and oil seed rape crops grown for food.
How are the logs bound together?
A combination of natural lignin in the straw and oil seed rape cake heated under compression binds the raw materials together.
Is the straw carbon neutral?
Yes, STROGS are carbon neutral as the carbon absorbed by the crop growing is released when burned and in turn is reabsorbed by next years crop.
Are they better than wood or coal?
They can be burned with or without other solid fuels. They have the advantage of being clean to handle and dust free. They are drier than wood and do not need to be seasoned before use. They leave a little more ash which can be used as a garden fertiliser.
Do I need kindling to light the logs?
You can if you wish or break the logs into smaller lengths (5-7 cm) and use a firelighter to get them going.
How big are the logs/pack?
The logs are about 26 cm long and 7cm in diameter. There is five logs in a pack. The pack weighs around 5kg.
How long will they burn for?
The burn time depends on the fire and air flow, however a 1kg log has a burn time of around 40 minutes to an hour. A pack will last around 4 hours.
What is the heat output?
A 1kg log has 4.5kw hours of energy, which equates to 1kg of kiln dried wood at 20% moisture.
Do the logs spark?
No, the logs do not spark.
