we have a wood stove that we burn wood in to offset gas furnace cost. Needless to say I'll be burning a whole lot more next winter with the higher prices. The price of wood depends upon where you are in the country. Right around a large city seasoned split oak will sell for alot more than out in the sticks. Around Kansas City seasoned Oak split will bring from $75 to $150 per truck load. Usually takes 3-4 long bed truck loads to equal a chord which is 4x4x8. A lot of wood cutters talk about a rick which is assumed to be a 1/2 chord but in forestry and the division of weights and measurments I don't think there is any offical measurment of a rick. I've heard of guys selling wood as a rick that was simply one full long bed truck load which isn't a 1/2 chord. Unless you have racks on the truck and stack it over the cab you can't get a 1/2 chord on a full sized long bed p.u.
If you are going to buy wood to burn you want wood with the highest BTU's. Hedge(osage orange) burns hottest then I think it goes the oaks, red elm, hickories, ash, hackberry, walnut, american elm, and on down. I try and cut only red elm, left over hedge from cutting post, and oaks, a few ash, hickory and hackberry.
I usually burn 2 chords per winter some years more some less. I think this past winter I used approx 2 1/2 chords and have some left over. Again this isn't my primary source of heat.
Depends on the kind of wood your cutting but $50 for seasoned hardwood sounds right but if it is all split and not so much limb wood it would bring more.
PS if buring hedge usually not a good idea to fill a stove completly with it. It can get so hot as to buckle the metal in the stove, cause a flu fire, and so on. I try and only put a couple of small hedge sticks in with some other type of wood.
