larsg So just to make sure I got this right: You actually worked on the Duetto and you advise against this machine? Because it is bad? Or just because the Bianca is better or more modern?
18 years ago I did the top level specification, design and testing for the Duetto.
- Boiler sizes
- pump type
- case used
- PID Control and PID Tuning
- Steam boiler on or off
- I completely designed the specialized preheat system in the service boiler to prevent it from being able to overheat the brew boiler. Mainly because they used to large preheat tube. Although in the end my design made the preheat very stable and consistent.
It was based on my thinking and knowledge 18 years ago…and has not moved on much since, except to do some things I wanted at the time, that they didn’t do, especially with regards pump mounting. It was the first machine of it’s kind that set a trend in the espresso world, but they didn’t move on with the design..
I have Duetto number 0001…..the first machine ever made….which they gave me.
The Bianca is modern, up to date and a better machine, or as people have said, stretch to a Vesuvius, if you want the Ultimate in profiling, temp stability and on off preheat (if you want to use it in a cafe), plus a mechanical disconnect of the preheat system from the brew boiler to prevent heat syphoning..
I was heavily involved in the Vesuvius and a tiny bit in the Bianca (I have the prototype) and I also have the latest Bianca (I had that for almost a year before launch).
I think you would love the Bianca…(or the Vesuvius)…or perhaps something from left field, the Vesuvius Evo Leva.
