tompoland heater cartidge in group head for temperature
stability versus two cartridges in the Vostock.
I had always thought that the system and layout of the group heaters were pretty much identical between Nurri and ACS, particularly since TOF is now making both groups… Two cartridges are necessary (or ‘better’ if you prefer) as they each sit on one side of the group; if you had only one, it would be difficult and time-consuming to heat the group consistently throughout and “keep it there”, as there is a large volume of air (the sleeve/cylinder/brew chamber) in the middle which does not conduct heat all that well.
tompoland Will ACS be cannibalising the Evo sales
I would think yes, to some extent. If the Vostok 1 group had been available 6 months ago, I would have ordered it instead of the Evo, as I prefer the looks (added features are nice, but not a deal breaker, and they are expected to be ported over). The size of the Vostok may prove problematic for some - the Evo is a bit smaller, although by no means small!
However, I think cannibalisation is a non-issue, in the sense that sales that would have gone to an Evo will go to a Vostok instead - both benefit from using components - and presumably tooling - from other machines (Multi-group Vostok, Vesuvius, Minima), so it’s not like there would be a critical volume below which one or the other becomes infeasible or unprofitable, or at least not quickly.
