Heating 3000 Square Feet for about $800

In calculating how much money we have spent on wood so far since we installed our Sedore in January we have spent about $400 for 3 months. Extrapolating back we figure we could have heated our house for the whole winter for $800. Now this also figures in some wood that we scrounged, but did not have to cut. In the last several months I have become a wood scrounge looking for available fire wood where ever I might be.
For this savings is huge, because up until this time we heated with oil and at $3.59/galloon there is no way we could have made even two months at $800. So for us we are easily going to recoup the cost of our stove within a year.
