Subject: boiler insulation options
I plan on insulating the boiler on my Isomac Venus this week.

I have an order en route of the ceramic fiber insulation that everyone
has been using
( http://www.infraredheaters.com/insulati.htm Ceramic Fiber Insulation
)

Doing some prep work, I found out that the insulation is essentially
like home fiberglass insulation -- it busts into particles and is some
pretty nasty stuff.

Its fine for hx machines, etc -- but the group on the Venus is right
below the boiler -- and there's quite a bit of clearance around the
boiler and directly above the drip tray. If the boiler were nowhere
near the group, i wouldn't care. But something that sheds right next
to a vibe pump and above my coffee.... its a recipe for something bad.

In other words, I'm likely not going to use the stuff I bought. It can
go in my Expobar fine, but i need to find a non-shedding type of
insulation.

Can anyone offer some options ? I'm trying to find out exactly what
the neoprene-like stuff some boilers is.

The only item i could find was the Aramid stuff on mcmaster carr :

Aramid Sheets
Aramid + Fiberglass

Im open to any ideas.

possibly. whats the size / thickness ?

that's the exact material i think i should use.

but my boiler is *tiny* -- i need a roughly 10" x 3" strip, and
possibly a 3.5" square piece as well.

its very likely that we'd both be better off if i just get the cheap
one from mcmaster-- and your remaining material goes to someone with a
larger boiler. i have an expobar too, but its boiler is tucked away
where i don't need to worry about fibers.

I discarded the ceramic idea after reading the material data and a few
cautions
My PID / Insulation project is here
http://www.ielogical.com/coffee/VBMPID.html

This is what insulated looks like

This is what I used
http://www.mcmaster.com/nav/enter.asp?partnum=87485K66

This is the 'wisdom'

For my $130 I had no smell, easy to work with, no fibres. A bargain as
far as I'm concerned

I have over 1/2 a sheet if you are interested

Howdy Ian!
I'm about to insulate a Nuova Simonelli Mac boiler. If you still have a
half sheet I could sure use it

I find your handle offensive and juvenile.

In other words, GFY

Thanks.

I hadn't seen that paper/felt on their website. I would have bought
that instead had I seen it. Annoying.

I reached out to some silicon manufactuers trying to source some
silicon sponge to use on the boiler.

I didn't mean the amount of shed is nasty, just the product. If i were
to use the ceramic blanket on my Isomac, the blanket would be directly
above my cup. I think fiberglass shards are particularly nasty, and do
not want even 1 shard a week shedding into my cup -- much less onto my
hands.

I have used it, and it isn't my favorite. The blanket does shed a bit, but I
think 'nasty' is an exaggerration. What I like and recommend is the ceramic
paper (actually more like felt) from the same company. It doesn't shed and is
much easier to work with. http://www.infraredheaters.com/550-k.htm
