The thing would be to use something that does the trick and is UL, but
isn't designed particularly for WVO. I'm thinking block heater probes
perhaps.

Any commercial waste oil boiler will run heated veggie oil.

Huh? I can't see a block heater probe being UL _for the application_.

I believe the guy was looking at heating the oil.
Instead of the question of heating with the oil.

Hmmm. I guess I should have been more specific. In the first place, I was
hoping to avoid the pre-heating, as requiring a second heat source would
pretty much negate any advantage I can see, and secondly, it needs to be
fairly small - so probably not a commercial waste oil boiler.

Ah. I see the confusion, but I still doubt that using a device for an
unapproved purpose is UL-approved. But indeed, I was wondering about
heating _with_ WVO.

Then the answer is no.

Oh well. Too bad. Is vegetable oil really too viscous to do this, or is it
just a matter of nobody having built a commercial unit (I can see the
market may be a little on the small side :-) )?

both. commercial guys don't see wvo as a fuel, so no UL stuff made
specifically for it. Many of us are modifying equipment to burn it
though over at wastewatts at yahoo groups.

Thanks Steve. I hate yahoo groups, but I think I'll check it out anyway :-)
fwiw, UL is pretty important if you want your insurance company to pay up if
you ever happen to have a fire. Most of the waste oil burners I've ever seen
are home-built jobs, and that's fine if you're rich or are never going to have
a fire...

Most of us play with them in a separate building, and pipe hot water to
the house ...

Yeah, but that's a solution that would have been far better chosen _before_
we built :-)

We install them as retro-fits. the house didn't need to be desined for
it. If you have hot water already, its easy to plumb in another boiler.
If you have forced air, we put a heat exchanger jst after the main
blower in the plenum. I'm installing hot water in my house, which never
had a central heating system. Drilling holes and running pipe.

Agreed. A million years ago, when I used to work in biotech, we did
have "in-line" electrical thermal probes for heating up the benchtop
fermentors. They would have been ULc.
Not cheap, though.
That's kinda why I was thinking a block heater probe. True, not the
purpose for which it is designed, but at least professionally
manufactured to some standard, whatever it is the "car guys" use. I'm
an industrial mechanic by trade. Our omnipotence is supposed to end
when you slap wheels on something ;-).
