Will,
WADR, where do you come up with exactly "WHAT IS PERFECT", especially given the huge discrepancy in density between yellow birch (or black birch, for that matter) and gray birch, which is REAL junk. As Eric said, aspen might be good when that's ALL that's available, but it's hardly a hardwood. Agreed, it's NOT a conifer, but if you stuff your stove with it, you're not gonna get any overnight burn with it, unless it's a 50-55 degree night and you're throttling the air intake such that there's almost no heat getting produced.
AND, the same applies to your woodpile, ie, you'll be stacking and storing a fuel of very limited BTU content. Personally, I want the densest fuel I can get. If it was my fuel oil tank, I wouldn't wanna be STORING watered down fuel oil just because I got a good deal on it.

Grey birch ? Black birch? Hardwood or softwood ? One of the things I find interesting on the forum is the regional differences in the names for various trees.
It's all relative. Besides birch, the only other available hardwood we have here is Balsam Poplar. (Any material I've been able to find classifies it as a hardwood.) I would love to be able to burn maple, oak, hickory or any of the other hardwoods you guys are always talking about, but they just DON't grow here. Or even within 300 to 500 miles of here. I always say that it hardly seems fair that the areas that get all the "good" wood are, on average, 20 degrees warmer than here.
As far as the relative merits of burning Balsam Poplar, I can only tell you that in over 30 years of wood burning experience I will take poplar any day.
2 qualifiers - 1) of the wood we have available here 2) not the same stuff Warren is talking about. Maybe it's OK, I don't know.
Most of that time burning poplar was in the first generation "airtights" like Fishers or Timberlines. Stoves we wouldn't even seriously consider these days. And yet, poplar (ok, maybe some birch mixed in as I mentioned in my post) kept us warm all night at -40. No bull.
Now, the other thing to realize is that our average houses have minimum of R20 in the walls and R40 in the ceilings. Most newer homes are insulated even better. And no uninsulated crawl spaces or anything either.
So, if I had a ready supply of maple, oak etc. would I waste my time on poplar? Maybe not. But like I said, for what we have here, it heats good, burns very clean if dried properly, and is readily available. Sounds like three of the best qualities we look for in wood to me.
