I'm burning every day, and have been for about two weeks. Turned the oil furnace off when I got the electric hot water heater turned back on (hot water has been heated by a zone off of the oil furnace for the last ten years so I was stuck with it), and am now enjoying not paying for fuel oil for awhile. Not burning 24/7, though, just in the morning when the house is cool and then another restart at 7 PM or so.
