Has anyone considered a tank engine heater for heating WVO? Like this: http://www.jcwhitney.com/autoparts/Product/Pr-p_Product.CATENTRY_ID:2000837/c-10101/Nty-1/p-2000837/Ntx-mode+matchallpartial/N-10101/tf-Browse/s-10101/Ntk-AllTextSearchGroup?Ntt=engine+heater

Or like this:

You could put your pump behind it so that your pump does not have to deal with the hot oil, send the WVO through the heater to your filters, and then let it settle.

thoughts??

i've never seen those before. i'm not sure if they'd work as it says 16-25 quart capacity, etc...woulnd't one need something with a bit higher capacity? the amount that the thing would stay on/heating may shorten it's lifespan considerably?? cool idea though, just not sure if it had enough 'umph'? the big one is a 30 quart capacity..8 gallons...hmm

You may be right. I am not sure if it can keep up with the flow.

I have seen where some people "cycle" their WVO. It might work real well for that!!

Any other thoughts?

i thought one would have to go much higher than that to make the oil dry...
but i'm a nub so, perhaps you are right.

I've had people tell me 150 is too high even. 150 is fine though, it will free up the water and settle everything nicely. The only thing you have to worry about with heat are convection currents. Strongly centralized heat sources like water heater elements create convection currents that never allow settling until the heat is off. My heat drum with the heat wire heats the whole drum evenly so I can settle the oil out even with the heat on

i'm going to try and get a used water heater somewhere. it's already got the drain in the bottom, and an element. there is a plumbing place just up the road that has a bunch of 'throw aways'. imma try to find one without a hole.
now that will take care of the heated settling process. but i still think i need to do the water heater element and some iron pipe feeding into that ...so it'll dry the water out ...

thoughts?

forgot to hit refresh...hmmm that is a good point...well...how bout...heating the wvo hot/steam comes off as it pours into the reclaimed water heater...then DON"T use the heater's element, and just let the insulation keep it hot long enough to settle...then...after a while, drain the bottom off and pump out the good wvo...??

If you want to use a water heater thats fine, lots of people have done it. Use only the lower heating element run at 110V. Once the oil reaches a satisfactory temperature, shut off the heating element and wait for some amount of time. The time once the heating element is off is your crucial settling time. Use a lot of insulation around the tank to keep the heat in while the element is off.

I live in cold climate, summer is only 3 months long and never gets above 80 F. I only add Supreme Gas to my oil when it drops under 45-50F. Never more then 25% at the coldest time in the winter when its -10 to 0 F.

You live in a cold climate? Do you use a blend all year? How cold does it get?
