Rocky and Ms Silvia is a great combo. I have a Rocky that I modded to a stepless. There was a step up to the Super Jolly but only required with a commercial machine.
People.get more out of the Silvia with a PID kit but if you know the machine and temp surf you can get great.shots.
My FAEMA runs 24/7 and is plumbed. I lagged the boiler and do all my own maintenance including new rotary pump, group.seals, pressurstat diaphragm etc.
Cheers
