I have a large furnace oil tank that I am getting rid of. It is already loose, and sitting in my garage. Its not rusty, doesn't leak, and has a few gallons left in it. I think its around a 250 gallon tank.
Makes a great waste oil tank.
Its free - take it away.
If you want to, you can take the oil furnace also which is in the garage also. It worked, but most of the ducting has been removed since I have radiant gas heat now. It has a beckett AFG burner IIRC and is a 110,000btu unit. The date on the burner is 2008, but it looks like the rest of the unit is older.
