Outdoor wood boiler. It keeps the wood mess and smoke outside. Plus you can either stack wood near it or use equipment to move it in bulk, rather than carrying wood inside by hand and re-stacking. They got a bad rap because of poor efficiency (the first generation was essentially a barrel inside a barrel) and people's tendency to burn trash in them, but newer models are two stage gasifiers just like modern wood stoves.

Although honestly I kind of still want a heat pump for the shoulder seasons and the times I'm away.
