Yes, usually a Sirai, but those prices are way to expensive.
Pressurestat possibly £35+VAT at most. Look for the model number and

Looks to me as though it's a Sirai P302-6. Ebay has a Sirai stat in
the US for 65 bucks, and I've found someone here (Zoedale) with them
for £30 plus VAT and postage - any other preferred suppliers?

On most grinders, unscrew the top burr (adjustment collar that the
hopper is fitted to). Remove and replace top and bottom burrs.

Yep, got to that point after working out it was a L/H thread. How do
I tell if the burrs need replacing - I've seen references to them being
'sharp' but it's difficult to know what that really means in practice.

Again, would be grateful for parts sources - pretty sure it's a Mazzer
Major (certainly needs 83mm burrs), though there's an Ebay seller
with stock.

Spotted your reference to lagging the boiler

Look at the images in the exploded views of my machine.

Think I'm being a bit dim as I can't spot the images with the lagging
visible. No matter, sure I can find something .... Foil backed foam,
you say - should be OK.

Thanks again for help & comments

John
