Well I think I finally found the right setting for my stove to give me most heat/burn time. About a 1/2 to an 1" in from full choke down. Outside is 28 degree's and house is 66-68. That works for me. Still wish I had bought a soapstone but oil man hasn't been here in over two months and tank at a 1/2. Hasn't been to to cold though but still saving money on oil.
