M67 Immersion Heater for removing water from WVO Intro

I bought this US Army surplus heater for removing water from the veggie oil that I turn into biodiesel. Having water in the oil will form damaging soaps in the finished biodiesel product which will damage or even destroy injection components.

This unit requires no electrical power to start or run. These units have been around for over 60 years and this one was made in 1991. I have been using this heater for the last 5 batches of biodiesel and love the fact I no longer have to heat the oil in my reactor, thus extending the life of the heating element and driving down electrical power costs even more.

I'd say it burns a couple quarts over about 4 hours. The fuel rate is just described as having a 'string of pearls' dripping from the fuel tap.

Please look at the other heater videos I have to see further details. In short, I follow the instructions on the unit to get the draft started through the chimney, and then ignite a small piece of biodiesel soaked newspaper to initiate combustion.

how much oil does this burn per hour and is there only 1 setting?
