What most folks burn is known as
cordwood. Which is simply short chunks of wood that fit the stove and are easily handled.
What species is very location specific.
Here we have good heavy hardwoods like Oak and Hickory. Places like Colorado use things like Tamarack and other softer woods.
I made it through a whole winter at 44 north latitude just burning pallets I cut up with an electric sawzall and collected from behind businesses.
I fetch wood with this rig now:
And stash it here:
Burning wood is very satisfying, hard work. I wouldn't have it any other way!
Starting out flat footed you will likely need to purchase cordwood. Look in the local paper for firewood sale ads.
There are several items you need to cut and gather your own firewood:
Chain saw(s) & extra chains.
A way to transport it (pickup truck or tractor & wagon)
A way to split it (Splitting maul, power splitter)
The time (often hardest to find)
A place to cut it if your land does not have the resource.
Gas, oil and maintenance on the equipment.
Split body wood is the best stuff to burn but is more work.
If you buy cordwood, you can often save some cost by hauling it yourself if you have a pickup or buddy with one who will help.
I have done this for most of my life so there are parts I don't even think of as part of it so I may have missed some details.
There is a learning curve on running the stove. It is a bit more involved than setting a thermostat most are used to.
Good Luck on it.
