1. Dual Boilers
Lelit Elizabeth
Summary: non-E61 group head, dual boilers (300ml brew, 600ml steam)
Pros:
- Dual boilers, good temperature stability with good PID software
- Fast warm up (15-17 minutes), silent vibration pump
- Adjustable electronic pre-infusion time
- Has a brew pressure gauge
- Programmable timed shot buttons
- Cheaper than many other dual boilers
Cons:
- Subjective looks - could be ugly for some
- Build quality is decent only (some said not as good as MaraX/Profitec but some said totally fine)
- No flow profiling
- Small water tank opening with tubes on top, not so elegant (See Image)
Profitec Pro 300
Summary: non-E61 group head, dual boilers (400ml brew, 750ml steam)
Pros:
- Dual boilers, good temperature stability
- Fast warm up
- Simple design, good build quality
- Cheaper than many other dual boilers
- Small form factor
Cons:
- Subjective looks
- No flow profiling, no adjustable pre-infusion
CREM One 2B Dual (not to be confused with 2B R-LFPP Dual)
Summary: E61 group head, dual boilers (1.2L brew, 1.7L steam)
Detailed review of the R-LFPP version (note it's not the same variant)
Pros:
- Large dual boilers, good temperature stability
- Modern design with dual manometers (brew & steam pressure gauges)
- Easy access to water tank, no tubes in tank
- Large drip tray, and brew boiler can empty into drip tray easily
- Seems to have better build quality than the Profitec Pro 300 / Lelit Elizabeth
- Possible addition of flow profiling kit ala E61
Cons:
- This variant does NOT have built-in adjustable pre-infusion or flow/pressure profiling unlike the R-LFPP variant
- Lack of user base internationally, hence have to rely on reseller support (not italian brand so parts are also rarer)
Breville BES920 Dual Boiler
Summary: non-E61 group head, dual boilers (0.3L brew, 0.95L steam). A good machine for those who are willing to mod or those who doesn't mind a kitchen appliance looking machine.
Detailed review of the R-LFPP version (note it's not the same variant)
Pros:
- More affordable than other dual boilers
- Adjustable pre-infusion, possibility of slayer mod to do pressure profiling
- Good temperature stability
- Fast warm up
Cons:
- More plastic in the build, looks like a toy (subjective)
- Does not seem to last longer than other brands
- Almost impossible to find replacement parts, need to rely on reseller's support or warranty
- Non standard portafilter design (even though it's still 58mm)
Other good candidates: ACS Minima (one of the best valued dual boilers too), but it's hard to find one in Malaysia.
2. Heat Exchange (HX) Machines
Lelit MaraX
Summary: The most temperature accurate/consistent HX machine, since it comes with 2 temp sensor (1 at HX, 1 at the boiler).
Pros:
- Good temperature accuracy unlike any other HX. Set at one of the 3 temp settings and it will stay at that range (91-92C / 93-94 C / 95-96 C). This means no cooling flush is needed unlike other HX.
- Dual manometers (brew & steam pressure gauges)
- Silent vibration pump with a gradual pre-infusion by the pump* (see cons #3)
- Possible to add flow profiling kit (like Bianca)
- Wide water tank with no tubes on top (image)
- Light weight (18kg) and small form factor
- Possibility to add a live data display addon to display temperatures (See Image)
Cons:
- Fast warm up (20mins) but to reach perfect temperature, it takes about 30-35mins to stabilize to your target temp
- Not ideal for many back-to-back shots. Temperature will slowly shoot up 3-4 mins after the first shot, so you have a "window" of good temp shots. But if you time your shots well, no problem at all.
- If you need to pull like >5 shots consecutively, you can change to "steam priority mode" where it acts like a normal HX, so pulling back to back shots is similar with Profitec 500 or other HX.
- Pump flow rate is lower than others by design (max 4.5ml/s). Not really a cons here, as you usually don't need more than 5ml/s flow rate.
Profitec Pro 500 (PID)
Summary: One of the more temperature consistent HX that does not need that much of cooling flush, but you might still need a quick flush (it depends). As with any HX, you might need a group head thermometer installed if you want to monitor the temp.
Pros:
- Better temperature accuracy compared to other older HX like Rocket Appartamento etc
- Good build quality and good looking
- Dual manometers (brew & steam pressure gauges)
- Possible to add flow profiling kit (since it's E61)
- Wide water tank with no tubes on top
Cons:
- It's still a HX machine, cooling flush might be needed for the very first shot you pull. And you might need to install group head thermometer (or use a SCACE) to know exactly what brew temp you get. However, consequent shots could be more stable.
- E61 typically needs longer warm up time (30+ mins) due to the big chunk of metal
3. My choice and reason
I went with the MaraX because of my unique situation:
- My kitchen space for espresso is very small and only machines like Profitec Pro 300 or Lelit MaraX can fit.
- I had a budget of max RM7000 at the time of purchase (but ended up spending more because I bought bottomless portafilter, flow profiling kit, walnut knobs...)
- I like the looks of MaraX the most
- I like the possibility of adding flow profiling
- I like the simplicity of MaraX - no cooling flush, just walk to it and pull shot then steam
- I don't have a need for many consecutive shots, at most 3, so it's fine.
- I don't like Profitec Pro 300 even though it's a dual boiler - mainly due to no preinfusion and flow profiling. Lelit Elizabeth seems good too but not the looks.
If I have a bigger space, I would still choose the MaraX with my budget. With a much higher budget I might opt for the Lelit Bianca. Else, the rest seems to be diminishing returns. The next level jump could be at GS3 / Decent Pro level.
