Not to be critical, but is he burning unseasoned wood?
Most people do. Most people don't know the difference.
If you are burning hard woods (notice I didn't say hardwoods) like oak, you need two years to call it properly seasoned. I used to see people say that on forums, and I scoffed at them as fanatics and woodburning elitists. My 6-12 month wood was burning just fine!
Then I had the chance to get a bunch of honestly two-year seasoned wood, and found out that I didn't know what I was talking about. The difference was amazing.
Now that I know better, I have found the same to be true even of pine. I don't get much pine, and I keep it for shoulder season, but still, I have now burned enough to know that 6 months is not enough. Pine needs at least a year in my climate (Virginia) and it's noticeably better at two years.
In terms of ease of lighting, long burns, BTUs, and less creosote buildup, 2 year wood is far superior.
The downside is that you need more room to store your wood. I only have an acre, but I manage it with 4 pallet bins that hold about 2.5 cords each, and I burn about 4-5 cords per year, so that allows me to rotate bins and keep 2 years worth on the property.
My wood stove is my only source of heat, so it matters to me!
Of course, if you live in a very dry climate, like, say, Flagstaff, your wood will dry faster.
