Heating with a wood stove doesn't really have a 'medium' setting.  You get 100% while it's roaring away, and that slowly diminishes as the fuel burns down.  (Yes you can adjust dampers, and air-flow valves to "slow it down"; but that doesn't really work/happen.)

  I've lived in a home heated by a wood stove for 10 years.  You would build-up the stove so it blasts away, goto bed, and by morning there would be enough coals left to start it up again but quite chilly in the house.

  There is nothing like it.  I love it.  I don't have the same access my father did to family farms, wood lots, and trees.  Today I would look into rocket mass heaters.  Spread that heat out and allow it to more slowly heat a house.
