Talking my mechanical engineer friend about the benefits of keeping wood covered last week. His school of thought is you don't need to keep it covered because that's what his dad did. But he is a mechanical engineer, you would think that he would have given this some thought. Each pound of wood contains about 1,000btu. Each pound of water in your wood takes 180btu to bring to a boil if you bring the wood inside and throw it in the stove. Then it takes 144btu to boil the water, then the steam takes 1/2 BTU per pound to super heat. So the water starts at frozen. That's 30btu to thaw, then 180 to boil, 144 to boil it off then 100btus to super heat steam and it all goes out the chimney. That is 454 BTUs per pound of frozen water that goes in your wood stove and wasted as discharged super heated steam. So keeping your fire wood dry means you could save hundreds of pounds of wood per year.
