Question New heater for WVO pic's

Has anyone ever used this type of heater for their WVO?

http://svopower.tripod.com/produits1.html

btw...It 's in french but picture explains it well...

I am soon doing WVO with single tank in south Florida but may want to get insurance for heating WVO prior to Ip based on what I've read here and this looks pretty cool....

Isn't it a catch 22 to wait for the engine to get hot before the WVO heater is operative?

Is Prestone French-Canadian for coolant?

I don't see how this could get your VO hot enough... It doesn't spend enough time with the heated coolant. What about all the other length of fuel line? Just let that gel in the winter? Seems like a good idea, but in practice I can't figure out where it would be useful.

I have a similar one made by a place in Oregon. In reality it gets the wvo up to about 140-150 I'm guessing - not hot enough according to current thought, though my car works fine. I plan to add a vegitherm this winter.

Heat exchanger

The issue is temperature rise; and how warm (or cold) wvo is going in. Judging by the sketch (which may be simply diagrammatic) , there is not alot of heat exchange surface, which would mean a minimal temperature rise. Could be a workable component for a system in a warm climate or even used in tandem in cooler climes.

Why not just rap some metal fuel line around the exhaust pipe?
It'll get plenty hot there.

I'm curious if anyone has tried using the exhaust pipe or manifold for a heat source.

If u have auto trans, might work if u get an external trans oil cooler, disconnect the line thru the rad.
Then run the veg oil line thru the rad for trans. To warm it up.
I guess u need to have some warm up time before switching to veg oil.

I figure there's plenty of good heat sources under the hood that would work faster and better than a coolant heater. I'm going to place a meat thermometer in variuos places to see if something will work better. What would happen if the oil is too hot?

If oil is too hot it gasses. YOu get vapor lock I guess. Also the vapor is explosive like any other fuel vapor.

Do a search for "Exhaust" on MauiGreen/Infopop. Its been discussed there. Basically it gets tooo hot and is very inconsistent in temp range. So far from all my reading no one has done it successfully using exhaust heat as primary heat source. Maybe you'll be the first?

Wvo

Lots of good info & good, if not cheap parts on Frybrid.com.

He has also designed new 3-way valves as he found that the Pollacks everybody (incl him) was using died pretty soon when the WVO was actually heated to the proper level -- 160F. I am planning to use his exchanger & valves with a coolant hose - wrapped WVO filter, aux elec pump, plastic tank in the trunk (unheated as the climate here is mild in winter). If the WVO doesn't want to flow for a couple of cold weeks/yr I'll just use diesel. I'll also install a heat gauge in the fuel line to be sure the WVO is hot enough --- to avoid coking & subsequent engine destruction.

Why not

also use Chris's heated filter? I can assure you that you will appreciate it after changing the filter a few times and having to deal with coolant hose wrap.

Good luck,
Jim

I plan on probing around the engine compartment for an alternate heat source. There are plenty of warm spots to consider.
Is it true that the pollack valves fail when running hot oil through them? I've got one and it's not that cheap of an item.
