If you buy your logs from Bertie’s you will know that your firewood is guaranteed to be nice and dry and ready to burn, but are there are a few simple checks that can help you decided if a log is dry or still damp.
1. Dry wood is lighter than damp wood, the more it dries out the lighter it will get.
2. Dry wood tends to shed it’s bark and the end grain has cracks or splits.
3. When stuck against each other dry logs ‘ring’ and wet logs tend to ‘thud’.
4. Dry wood when split feels warm and dry, wet wood feels cool and damp.
5. Dry wood lights easily, burns brightly and gives off lots of heat.
6. Damp wood is difficult to light, hisses, spits and smokes, giving out little heat.
If in doubt you can always check how dry firewood is by buying a moisture meter. Ideally your firewood should have a moisture content of around 20% to make sure you are getting as much heat for your money as possible.
At Bertie’s we often get asked if you can save money by switching to wood fuel from other forms of heating. The answer is yes you could, but how much will depend on what fuel you are currently using for heating, how often you use your stove instead of other forms of heating and the quality of the wood fuel you use.
The latest figures from the Nottingham Energy Partnership, an independent body that monitors and compares energy prices, shows that the cost per kilowatt for seasoned logs is currently around 5.3p when the efficiency of the stove is taken into account. Given that Bertie’s logs are kiln dried to an average moisture content of 20% we would like to think that Bertie’s kiln dried logs should work out cheaper than ordinary seasoned logs. Here’s a list of common fuels with the price per kilowatt after the efficiency of the appliance is taken into account, prices relate to December 2014.
Electricity – 16.0p
Mains gas – 4.2p
Oil – 6.5p
LGP – 6.6p
Smokeless fuel – 9.2p
Seasoned logs – 5.3p
If you would like Ed to artfully stack your firewood for you then we would be pleased to quote. Owls are Ed’s favourite images at the moment, prices start from only £2000.00 (logs extra).
If you don’t need your logs stacked quite so artistically, don’t forget Bertie’s offer a Log Stacking Service to take all the strain and pain away from this chore.
At Bertie’s we try and keep our environmental impact as low as possible, we only use locally sourced coppiced timber for firewood production and use the waste wood from our log processing line to fire our log drying kilns. We use software to map the most efficient route for our delivery trucks to take each day and all the timber hauled into the yard is brought on the largest possible vehicles, thus reducing lorry miles. All our packaging is returnable and reusable or recyclable.
Every Summer Bertie’s likes to give you the chance to get your log store all stacked up and ready for Winter.
This year you can order a delivery of Bertie’s Kiln Dried Logs at last years prices, plus receive a Jumbo bag of kindling, a net of wood chunks, a bag of wood briquettes and a bag of natural firelighters for FREE.

The simple answer to this question is any wood that’s dry!
The slightly longer answer is that any wood that’s dry, but preferably dense too.
Timber when freshly felled usually has a moisture content of 50-60% and as with burning anything damp will not be easy to light or provide much in the way of heat. As a rough guide firewood like Bertie’s Kiln Dried logs with a moisture content of 20% will produce around twice the heat of freshly cut logs with a moisture content of 55%.
The density of the wood has an effect too, with slow growing hardwoods being much denser than quick growing softwoods. This means that you will need to burn about 4 softwood logs to get the same heat output as 3 hardwood logs of the same moisture content. Softwoods can also contain more sap and this can lead to the build up of tar in the chimney.
That’s why we produce our kiln dried firewood from locally sourced hardwoods including ash, birch, beech and oak.
