It has been a long time since my last post. But now there is news on the way. Saturday I am fine-tuning my Appia with a 1,75mm hx restrictor that should lower the brew temperature apr. 3 degr. C. This will make a dramatic change in my machine and should held decrease the cooling flush. I hope that it will increase temperature stability as well.
I will have it installed saturday - and hopefully I will have access to a scace device so I can measure the changes. I hope I will be able to increase the boiler pressure at the same time and thereby increase the steaming ability.
I will be back :-)
