Natural draft waste oil burner!Off grid water heater build part two!

This video shows how the water heater/boiler is assembled from two 55-gallon drums and some 3 inch exhaust pipe. I'm pretty happy with the initial results. I will be insulating and using this to heat an RV in part 3 coming soon! Thanks for watching! Don't forget to click that bell if you don't want to miss the final video!
