Hey Lorenzotti, that sounds interesting, I was over a few coffee repair shops on the weekend I could not find a suitable boiler. But I still have to visit some other shops. There are not that many in China
That 0.8L boiler sounds interesting, how much are they asking?
and shipping to china?
I want to build a single boiler machine for the moment, later on I will add a steam boiler (or just buy the milk steaming machine).
Anyways, since the original topic was the E61, I wanted to ask you guys the following.
The thermosyphoning circuit in a single boiler espresso machine using the E61, would basically remain always at brew pressure right? and therefore the boiler as well. Except the pump which will sit behind a check valve. (which will be at 9 bar anyways unless the pressure is purged).
And for brewing, what will happen is that when pulling the lever up of the E61, the pressure of the boiler will go down which will activate the pump to pump cold water at 9 bar.
Is this more or less correct?
I am a newbie, I dont feel so comfortable having 92C water at 9bar constantly on a homemade machine
hehehe. I need to ask if this is how its done because maybe I got it all wrong.
