longwood dual fuel furnace
My brother owned a house with one of those in it (oil) for a few years. Seemed to be horribly inefficient as the heating load for the place was only 81,000 at design temps and the Longwood chomped through nearly 35 face cord of seasoned oak. IIRC, he ran the oil for a month at one point and freaked out from the rate of consumption. I was never able to get the flue temp below 800* with oil and let's just say creosote was never a problem when burning wood. Personally I wouldn't mess with it. Get yourself a good gasification type wood boiler if you want to do the wood thing.
