The thermosyphon tubes have been
enlarged, the reasons stated are:
“Superior layout of thermosyphon system
resulting in optimum extraction. Generously
dimensioned. 20% higher volume as with
comparable machines on the market.”
and“Optimised boiler capacity to
thermosyphon system ratio. Results in fast
heat up time”
I always let a machine heat up for a while before I use itusually
about 30 minutes or more. What I can say is the Giotto was ready in
30 minutes and some other machines are not quite there after 30
min. In addition a thermosyphon with increased capacity can only be
an advantage in cold conditions or when pulling lots of shots.
My internal inspection shows a much longer route for the
thermosyphon pipes than before, especially the top pipe (probably to
make connections easier). I suspect this was also a reason for
increasing the diameter of the pipes.
This is a minor niggle and is becoming more
common. It’s nice to see a machine with a
factory fitted UK 3 pin plug, but I do wish
they would go to the trouble of fitting the
exposed pins with those plastic “plug”
protectors to prevent any risk of scratching
in transit.
The machine has external access to
adjust the pressure of the rotary pump.
Although it does allow you to adjust
pressure without removing the moderately
difficult to remove case, it is in a tricky
position, underneath the machine.
In addition the side panel fixings would have
to be loosened to relieve the case
sufficiently to get a socket in there to
release the lock nut.
I would also personally use a mains
plumbed pressure range of 2-3 bar and a
pressure reducer if necessary to prevent
exceeding 3 bar. This is contrary to the
Insert sheet in the Rocket Espresso
instructions, which state limiting line
pressures in excess of 5 bars
The mains water connector underneath,
which also handily swivels in any
direction.
I have no idea why the earth bond cable
is on the outside and not the
inside*..Totally baffled, if it was my
choice this would be inside the machine
where it can’t catch on
anything*.perhaps some EU rule?
