This was a test to see how much heat rise I could get out of a simple tube in tube water heater. The temp rise was sufficent that this would be easy to construct from junk and provide hot water in an emergency or infrequent use situation. See my other burner vids and tutorials here: youtube.com/user/glumpy10/videos.
The heater is powered by a waste oil burner fueled by waste vegetable oil. The amount of energy input for the temp rise is very inefficent but still worthwhile considering the simplicity of the setup, the fact it uses free fuel and the flow rate of the water. A 12V blower could easily be used instead of a mains powered unit.
Having the copper tube enveloped in flame gives much greater efficency than the normal thing people do of wrapping the tube which creates a very small contact area and leaves the majority of the tube unexposed to any heat and in fact able to radiate and gained energy out.
Despite the inefficency, this heater would be very workable for occasional use in a shack or other application where low cost and infrequent use required .
