Hi all you knowledgeable guys!
I thought I knew quite a bit about firewood - I buy lots of it for a large wood boiler which basically heats my whole house.
But now I have got really confused!
I bought some kiln dried ash and discovered it burned with considerable difficulty, heating my wood- boiler combustion chamber up to 350 degrees at best, when it normally burns at between 600 and 700 degrees.
I have never bought kiln dried before but after all that is said about it on various websites you would have thought you could trust that process completely (at least I thought so). All the same, I became, well, a little bit suspicious after getting back to the supplier, who at this point was uncooperative.
I started wondering if the wood was still wet inside - it certainly felt rather heavy.
So I used a newly purchased ExTech moisture meter, and on the outside of the logs, using the pin method, it was registering 12 - 15%, but when I used the scanning method it registered 30 - 35%. That measurement, as I understand it, takes account of moisture up to 1" deep. I knew I needed to split the wood to check properly, and this I did. This time, testing several split logs, I found that the inside was consistently around 22% using the pin method, but using the scanning method the moisture meter almost took off, bleeping like fury, with three water droplets displayed, and gave readings of 50 to 70%, shifting a bit as I moved it around because of needing a flat surface.
All this raises many questions in my mind - about the faith one should have in kiln drying, as well as the strange differences in the moisture readings (I set it correctly each time for either the pin method or the scanning method) and I got results (as above) that I find incomprehensible.
Not least, what I do with a cellar full of tightly stacked kiln-dried (probably wet) wood that came down via a shute and cannot easily be got out and a supplier who's not interested to know what the problem is.
Any answers you can give to any part of this query would be so much appreciated.
Cheers all! Have a nice day!
