Here is some advice for burning oak and ash logs in your stove or another wood-burning appliance.
The main thing to remember is that oak and ash are very dense species (with oak being denser than ash). This means the logs contain a lot of wood fibres, which is why they burn for longer than softer hardwoods, like birch, and every variety of softwood.
Because the logs are so dense, you will need to put a good deal more thought into building and lighting your fires (although this is less of an issue with logs that are as dry as ours).
If you build the fire with very large, chunky logs, it is likely they will not catch fire easily. So we recommend that you use firelighters, kindling and smaller pieces of logs to build your fire up before you start placing larger logs into your stove or burner. Always have your fire burning for a period of 5 to 10 minutes before you even consider picking up a larger log (in diameter, that is, as our kiln dried logs are 25cm exactly, although their width varies).
The bigger pieces are excellent once you have established the fire, especially if you want to create a long-lasting fire that needs the minimum of tending. Each one of the logs produces over 4kw per hour and should burn for an hour or more. Always let the logs burn down to glowing embers before placing another one on the fire, and you should never have more than two logs in your stove at a time.
Make sure you add more kindling or firelighters while you add new logs once you have established your fire.
If you follow these tips, burning oak and ash logs in your stove or log burner will be a joy. Ultimately, it is the moisture content of the logs that dictate how easily they light and the heat that is produced.
