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 ābetterā 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 ākeep it thereā, 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 itās not like there would be a critical volume below which one or the other becomes infeasible or unprofitable, or at least not quickly.
