In a previous life I was an insurance investigator & it would be extremely difficult if not impossible to prove that one suppliers logs caused a fire to a property. The home owner is responsible for what they burn in their fire & what precautions they take to minimize risk. Thats why your chimney should be swept annually & cert issued & the need for building insurance.

Well the ash I am burning tonight was stood up yesterday

Had to turn the stove down as burning very well

 

The MC will probably have been 30%-35%, as you know wood at that MC will burn reasonably especially if you add some primary air under the fire. Its one of the reasons Ash is so popular.

 

But and its a big but, get the MC down to 16% and below you will get over double the heat from the same log.

 

For the guys own use then its up to him what he does in his own home which from memory the original post was about. If selling it, a lot of people would sell at 35%. I came across some wet softwood yesterday, sold as seasoned, around 40%, taking the guy some 12% or so tomorrow. That will be the last crap that guy sells to that customer.

I ran low on wood so brought some fresh ash home, I was surprised by what I found, a 2.093kg 1/4 section felled just before Xmas started out at 31%mc wwb. I kept it by the stove where it reached blood heat during the evening s and plotted the weight. On the 24th I dried it in the microwave and it has regained about 3gramme a day since. Plot below:

I'll have to try the same with some oak.

That's going a bit ott,I'm sure 16% is the ideal for a number of reasons but the loss due to moisture between 32% and 16% is about 4% of the available heat.
