Moisture content

What's the point of getting to 12%?

[Johny Walker]

so ther @ 12% then the customer puts then in a nice damp place ,!!!!!

[Frank]

Haha. Just in a room will increase that content.

Average outside moisture in the air in uk is 20%, even in a barn etc. In a house it is around 10-15% depending on central heating etc, age of house..

To put oak flooring down over under floor heating it is usually kilned to 6% MC, but generally swells a tiny bit, as eventhen the MC of the air around is up around 8-12%.

 

I reckon that anywhere around 20-25% should be acceptable for logs.

I agree.

 

Most of the stove manufactures base their KWH or BTU out puts on beech at 22% MC.

I tried it today on some Larch got a reading of 23 percent,logs felt bone dry,ive not had any complaints yet,so i assume their ok.

No Tom, not "should be". 20-25% is perfect and do-able by drying outside with some sort of cover on top to stop rain but vented on the side to allow windflow which is the main thing needed for drying. Heat from sun helps but as long as its not freezing, then wind drys woods. Oh and they need to be just of the ground aswell.

HI TOMMER thats right mate jon

[Dean Lofthouse]

My logs were down at 20% in the open barn but because we have had a couple of weeks of high air humidity they have gone back up to 28%, even under cover

I had a digital moisture meter, iit was too unreliable to be of any real use, check yours by testing some logs, then weighing them. dry them out in a cool oven or on a radiator and then weigh them again.

 

12%logs will not absorb moisture indoors, most of your furniture will be less than 5% moisture, unless you live in a cave. However you will only get logs down to 12% if you kiln dry them as others have said.

 

Mine is all in the 18-25% range and I get a lot of positive comment, You have to remember that some species will be 60% moisture or higher when cut and yes green ash will burn but not very well.
