Clean Burn CB 500 (500,000 btu) waste oil boiler with the pipe and transfer pump. I used this for about 3 years to heat a 6000 SF house in Salida. It is in great condition. This can be used to heat your shop, home, garage or any building. It requires used motor oil, diesel, veggie oil as a fuel. It works great and burns very clean, no smoke at all. I invested $10,000.when I had this installed. This unit works great.
