Quick Mill · ThermoblockCassiopea (03004)
A compact, full stainless-steel dual-thermoblock machine from Quick Mill that lets you brew and steam simultaneously — a neat trick at this footprint and price point, powered by twin Ulka pumps with Quick Mill's own Pulsor noise-reduction system.
The short version
The Cassiopea is an honest dual-thermoblock thermoblock machine: quick to heat, happy to steam and pull a shot at the same time, and built to a standard that outlasts most appliance-grade alternatives.
What you must accept is that there is no PID, no pre-infusion, and no temperature control beyond the fixed thermostats, so your shot ceiling is set by the hardware, not your skill.
Why people buy it
- Dual independent thermoblocks allow simultaneous brewing and steaming with no thermal compromise — a genuine convenience the single-thermoblock class cannot match
- Steam thermoblock has a switchable side kill-switch, saving energy and extending component life on espresso-only sessions
Why they don’t
- No PID and no user-accessible temperature adjustment: brew temperature is fixed by the thermostat, leaving no headroom for dialling in temperature-sensitive roasts
The full tally
- Dual independent thermoblocks allow simultaneous brewing and steaming with no thermal compromise — a genuine convenience the single-thermoblock class cannot match
- Steam thermoblock has a switchable side kill-switch, saving energy and extending component life on espresso-only sessions
- Full stainless steel body, chrome-brass portafilter, and copper thermocoils signal a build quality well above plastic appliance competitors
- Twin Ulka pumps with Quick Mill's proprietary Pulsor pressure-stabiliser reduce vibration noise by approximately 30% versus a standard vibratory pump
- No PID and no user-accessible temperature adjustment: brew temperature is fixed by the thermostat, leaving no headroom for dialling in temperature-sensitive roasts
- Thermoblock architecture means each portion empties and refills the heat path, which can introduce shot-to-shot consistency variation compared to a true dual boiler
- No pre-infusion and no flow or pressure profiling: the machine is a straight-pull workhorse, not a platform for technique development
What the community knows
Years of owner threads, distilled.
Solid dual-thermoblock build and quiet dual-pump operation attract owners in European forums, but near-total absence from English-speaking communities (r/espresso, Home-Barista, YouTube reviews) means no crowd consensus on long-term trade-offs versus mainstream alternatives.

Worth knowing before you buy — Most owners who find one keep it; the problem is almost nobody in English forums looks for one.
Known weak points — Pump longevity documented in long-term use (8+ year machines report pump replacement; seals vulnerable if steam wand swung under pressure per manual)

Position in the market
Every dot is a rival, measured the same way. The gold one is this.
- Lower half for shot ceiling
- a higher ceiling than 81 of the 238 machines we’ve measured
- Upper half for build
- sturdier than 56% of the field, by the community’s own record

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who want user-accessible temperature control will feel the ceiling here fairly quickly. The natural step up is to a PID-equipped single boiler (e.g. Quick Mill Orione with PID, Rancilio Silvia Pro X) or to a dual-boiler machine for genuine brew/steam independence and temperature stability.

Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new machine gets blamed for it. While you learn it, a forgiving medium-light roast keeps dial-in kind — bright enough to taste progress, sweet enough to drink the misses.

Common questions
Can I brew espresso and steam milk at the same time?
Yes. The Cassiopea uses two entirely separate thermoblocks — one for espresso extraction and one for steam — so both circuits operate independently and simultaneously without thermal crosstalk.
Does the Cassiopea have a PID temperature controller?
No. Temperature is set by fixed thermostats. There is no user-adjustable PID, so brew temperature cannot be dialled in by the user.
Can I turn off the steam thermoblock when I only want espresso?
Yes. A side switch lets you cut power to the steam/hot-water thermoblock, saving energy and reducing wear on that circuit when you only need espresso.
What portafilter size does the Cassiopea use?
The Cassiopea uses a 58 mm chrome-brass portafilter with two basket inserts included.
How long does the Cassiopea take to heat up?
Multiple retailers cite 5–8 minutes for both thermoblocks to reach operating temperature. The thermoblock-per-shot purge design means the first shot after heat-up should be preceded by a blank pull.
Is the water tank removable?
Yes — the 2-litre tank is side-removable and includes a water-level indicator window.
