Ok, I know there are some smart kids here. I run a 4800w 240 volt water heating element for less than half an hour to heat 42 gallons of wvo to 130 f. each time I make biodiesel. I do this in an uninsulated metal drum but I live in temperate northern california. I've read that reaching `150 f. and then settling is good for helping break any water in suspension, so a little longer may be in order but I think even as low as 80 or 90 f. would help in the filtering process. Is the math for 240v half of that for 110v?
.5 x 48 kw x .5 hours = 12 kwh
My rate fluctuates around $.15 per kwh because of the type of property my service is on, so I'm figuring $1.80 for my use.
Can someone confirm my math?
I run my pump most of the time that the oil is heating to circulate as I have a feeling that oil may be super heating at the element. Anyone know if this is really necessary?
