Mine is wood only (actually it is a multifuel stove but the installer said that unless I went for a more expensive flue liner then acid from coal would corrode it, and I mostly burnt wood in the open fire anyway).
I'm trying to put out feelers for supplies of free wood. As luck would have it the weekend the stove was fitted, a friend was chucking out several lengths of old solid beech kitchen worktop (Ikea butcher block stuff). It didn't look that much but now I've cut half of it up into chunks with a circular saw it makes a decent size stack of wood - should keep me going for a while!
Even using a power saw it's quite hard work - once I'd finished sawing I was so warm I didn't need the fire on anyway...
