Absolutley spot on, but make a rough extimate of the elements area of contact with the oil (length*pi*radius squared) and make sure the output will be around or less than 3W/sq cm, this will ensure no burning of the oil whilst heating. Elsewise you will need to stir while heating. > > > I'm pretty sure that the > > combination of the heating element and the oil will end in a fire. Is > > this correct? > > Well, yes and no.

Are there two, then you should have no trouble. Use ohms law, Power = Current squared times resistance. The resistance will be the same on either voltage so it a simple calculation. Contact a specialist hot water / element manufacturer, and get a nice long element to fit. I did and they are wonderful (2 of) and they are feed in series on 240VAC to drop the power to the desired level. Always used fully submerged of course. regards, Matt ------------------------ Yahoo!
