After finding out that I couldn't purchase one of these plastic boilers
in the US, I decided to build one. Check out my link. If anyone has
ideas for further improvement, please pass it on.

Great work has been done on this by Pritchard in Chattanooga
http://home.chattanooga.net/~cdp/
and my neighbor in New Orleans,Ron laBorde

but don't go crazy like jason hayes did to make an all computerized setup
..the Corps of Engineers built shoddy levees here in N.O....they should,ve
consulted some technocrats like the local home brewers!!
I have used an electric water boiler for years and find that the
tremendous insulsulation possible makes it an energy effecient setup but
because the heat source is not at the bottom,temp readings have to be taken
in more that one place.The silence is amazing.
I boil wort with propane however

I should note, though, that Jason's is actually gas-fired. Very cool
setup, but light-years beyond a bru-heat.

There have been posts from several people who use these plastic boilers
regularly and never had a problem scorching the wort. I don't have
enough experience with a plastic boiler yet. The few times I used it, I
didn't notice any scorching problems. I was concerned too as you can
get a violent boil going.
Regarding the actual temperature rating of the bucket. That is a little
elusive. It depends on thickness of the material, etc. I will say that
it is just as rigid at 212F as it is at 75F. I can't say this for HDPE.
I did notice too that the link for the bucket changed. I will fix this.

I read this and reread it several times. It is very interesting.
I am not a polymer chemist either, but I know enoough about plastics
to be dangerous. Did Grainger confirm the temperature rigidity
of this pail?
My only concern is the possibility of LME scorching on the heating
element.
Thank you for linking directly to the appropriate catalog page

This does not happen unless you tip undissolved DME direct onto the element.
Always switch the power off when dissolving any extract or sugar into the
wort. If you are worried about the plastic not being rigid at high
temperatures you can clad the entire thing in wood which will also help
with insulation. I have stainless steel Burco tea urn with a 3kw 240v
element. The only problem you tend to get is that after a while the element
will cut out at around 90C because the boil-dry protection bi-metallic
strip can distort when you constantly use the boiler for hard rolling boils
but with 30 litres of liquid it ain't going to boil dry in an hour or 90
minutes. Always use a residual circuit breaker which will trip out if it
detects any problems with the circuit. I find I lose around 5 litres in an
hour rolling boil.

How intense of a boil can you pull off in that? I am curious how many
gallons an hour it can evaporate on a good day. I just finished a long
day boiling down a tripel, and this looks like something I'd be more
keen on walking away from for some amounts of time.
