DO NOT use any sheets with adhesive on your boiler!

Thanks for the detailed reply on the silicone. That must be some tough stuff if it can take 500,000 deg F.

I think that is 500 not 500000. And the boiler is probably always just under 300F while on.  So you need the 500 rather than the one rated for 300.

500f seems more realistic. I am not sure why they would list the spec to three decimal places, (500.000)

I have sourced some silicone sponge that should do the job. I can get the 5mm, (a little bigger that 3/16th") or the 3mm (1/8) for the same price.
Will there be any problems with the thicker insulation? I am not sure what size the original insulation is.
Also I have some aluminum tape that I was thinking of wrapping around the insulation instead of the worm clamps. Any opinions?
I have descaled the boiler and fittings, tapped the group head and am now waiting for the parts to arrive.

The only thing that locates the boiler ; group head HX feed and return steam line feed for the big Pstat and the frame shelf
relive the insulation at the shelf ,adjust the copper lines  either or both
zip ties not tape
silicone fine for on and off usage
24/7 usage silicone degrades at tight contact points
Aurella steam valve lever not Musica
with the gigleurs check how your coffee responds to no HX flush

Thanks for the information.
Is there any material that is better than the silicone? I am assuming even for 24/7 applications it is better than the standard insulation?
Would the plastic zip ties deteriorate with the constant heat? The tape I was suggesting is aluminum tape used on the insulation of my hydronic boiler.

Where is the best place to buy replacement parts?  

My Oscar needs a new pstat (Mater) and I think a new pump.  

I wish I were more mechanically inclined.  Any recommendations for a good repair tech somewhat local to Wisconsin?

yes plastic zip ties do deteriorate , yet are so easy to clean up , no sticky tape residue
am using factory insulation shinny side out and large zip tie  7.5mm wide 71cm long
chriscoffee .  has insulation I would try next

outer boiler temp about 118 c , anything you wrap around it will get toasty
do you want insulation that is a set and forget ,  or easy to remove at maintenance time

all things espresso are a balance of balances
