I'm assuming once you have the oil filtered, you can do whatever you want with it, meaning you can run it in a WVO system, or blend it in a separate tank for BIO, correct? If you dont mind me asking what did the total setup cost you? I'm very interested in this, and your setup looks killer. Also is your setup in a heated area? I'm not sure I'd be able to get mine in a heated area, but I think if I got an in tank heater from tractor supply or the likes, to put in that 55 gallon holding tank, I could then pump it into the hot water heater, heat it, and then just drain it an hour or so after it was heated, I would be OK. I like your setup though, but I think I would need to adapt it for my use.
