I tried a few packs of them last year. They burned well. I put them on my covered wood pile under a roof covered roof. I suspect a few got a little wet. They fell apart. Anyone else have this problem?

How are you getting those ratings? Are you calculating per cord or per pound? Pound for pound, all wood is the same. The difference being that one pound of pine occupies more space than a hard wood like oak.

If what you were saying were true, stoves would alter heating output based on type of wood. However, we know this is not true, but that denser woods burn longer with the stove putting out the same heat as it would for a shorter duration compared to less dense soft woods.

Obviously everything I said goes out the window when comparing wood with different moisture contents.

So for for compressed wood products, I don't buy the ratings, unless they add something other than wood. Perhaps they are able to get more BTU/Lb because they remove all of the air pockets from the wood making it as dense as possible.


Here's a study from the University of Missouri about heating with wood. http://extension.missouri.edu/publications/DisplayPrinterFriendlyPub.aspx?P=g5450

Because they are comparing BTU by weight rather than volume. Your stove doesn't give a rats ass how much the fuel weighs.

I don't keep them outside, a pallet in the garage and bring in as needed. If I didn't have a garage I'd put them all in the basement.
