The Rancilio Silvia is a fantastic machine. However, one criticism levelled at it is that it has a big temperature swing at the boiler. What this translates to at the group head is another matter, but this video illustrates the temperature swing at the top of the boiler. (Note that the PID control is disabled and just operating as a temperature sensor)
