Hello Everyone,
Been checking out different machines and it seems most contain an E61 Group of some type, even those machines in the $4000 - $5000 range. i just don't understand why modern machines are using these groups. The set extraction temperatures, like 93, have no relationship to what you might be getting at the group as, as far as I can tell, this temperature is just a calculated temperature and not the actual temperature at the group. Some machines even employ conversion tables from the boiler set temperature so you can hopefully get the right group temperature.
In this modern age surely we can do better then using a 1961 design. Yes there are PID heated and saturated groups but they are rarely used, and the E61 seems to be the main player.
Is it just money, ease of parts, easier repair and the hell with doing something better?
I would be interested in your thoughts. Maybe I just have it all wrong.
TIA
