  • single boiler machines

    Someone commented on newbie read too much information that the ecm botticelli had almost too much steam, not good for texturing, needed flushing after 20 min etc
    in my experience this is pretty common to all larger single boiler machines- the silvia or any other
    on my bezzera hx machine i need to flush any time i extract- unless im doing a constant line of coffees at a party etc- thats just the nature of most (read not necessarily all) machines with very hot water- sure e61 hx machines are the beesknees but dont get the idea they are perfectly stable (i have a little hx at work- isomac millenium and even it needs flushing and isnt more stable than other machines)
    re texturing i found that all single boilers ive fiddled with benefitted from the conical 2 hole tip (pr similar) from coffeeparts- the larger holed barrel one that came with the machine is the issue here
    another tip (no pun intended) is start emptying the boiler of excess water as soon as u turn on the steam switch and really empty that out
    i tried using a thermocouple and i found that the best time to extract is just after the heating light goes out- i have found that the ecm and silvia vary widely in temp through the boiler cycle- the difference i found with the ecm is that it is closer to ideal at just after the light goes out, not a case of wait 39 sec etc
    all the best

    anyone else with similar or widely differing views?

      Re: single boiler machines

      Telemaster, I do all that. There are limitations to a single-boiler machine. The biggest benefit of of a more expensive SB machine over, say, the Silvia, would be (potentially) greater thermal stability (which the Botticelli doesnt have) and the ability to make more coffees before the boiler is exhausted. In hindsight, I reckon it wasnt worth the extra $ over the Silvia.

        ROFLMAO

        Im usually the one that says that sort of thing, but being new here I have been trying to avoid showing my auditor nature.

          fullstops!
          ah the attack of the pedants- after teaching kids all day i like to relax

          certainly not intended to offend, were just all different?
          i think youll just have to cope
          what is important is i love coffee

          for david- to each his own- i guess for me i find the ecm easier than the silvia

          the ecm boiler is only 1/3 larger and the temp stability is more related to the deadband of the thermostat- quite wide on most machines, probably no diff between sivlia and ecm

          after doing thermocouple measurements i found that the temp at the beginning of the new cycle (just after light goes off) is pretty much what id want on the ecm, so i run water into cups, or use the hot water through steam arm to get the boiler light on

          -whereas friends have this definite temperature surf thing with silvias- im sure youve read about it- same old get boiler cycle going, then count down because the boiler temp is too high, then also issue of the over pressure valve being set a bit high

          i think they are all great but all are compromises- frankly ive been disappointed with the small hx millenium at work- so little steam (but has the same steam tip ive now got on the botticelli)- compared to the bezzera i was lucky enough to be given , its a bit sad
          i find it easy to estimate where the temp will be on the ecmsingle boiler- on the e61 machines you still have do the hx flush to cool the group head down and often there is still an element of counting - see:
          http://www.home-barista.com/hx-love.html

          also i started a new thread to discuss this so as not to be disagreeing with you- had strange (read negative) experience on coffeegeek where i offered an opinion and was shot down with a string of opinions all quoting telemaster said in mutually congratulatory tones suggesting i wasnt a seasoned veteran because i didnt talk in terms of low temp=sour, high temp=bitter - thought id save you that


          all the best

            Re: single boiler machines

            telemaster, I think the point about full stops was that your first post in this thread was difficult to read. Relax all you like - if you can double space between your points, as in your last post, then you can give e.e. cummings a run for his money and we can happily read and follow your line of thinking

              love the reply viviane- was going to mention said poet, but thought would look like mega snob prat with delusions of grandeur!

              point taken, still surprised its an issue- for me i guess its just a habit from making notes etc

              brett

              only problem is that now im suffering from disconnectedness from serious double spacing sydrome (SDSS- have to add that to ADHD etc)

                  Maybe Im a pedant. I hate messages that arent punctuated and arent capitalised.

                  Dont get me started on spelling!

                    Hi, Ron. At least you admit it- I get upset about spelling though I certainly wouldnt correct it or draw attention to it unless either asked by the person for help, or in a teaching situation.
                    The reason is both humorous and pathetic- my mother still talks of Dad (a teacher) correcting her grammatical and spelling mistakes in the love letters she sent to him!
                    Be assured, many people Ive corresponded to use a lot of shortcuts in their notes and thoughts.

                      Ron, I will notice punctuation and spelling errors, though Im used to the fact that written English has become very laid back since the internet took off.  I particularly notice it in my sons school assignments - we went through a stage of me helping him rewrite them into "correct" English.  He tells me that his teachers are a lot more tolerant of internet-speak than I am.  Makes  me fear for the future of the modern world.....

                      Brett, and your mother still married your dad????  He must be a pretty cool bloke apart from that.  Have to say, though, I was disappointed - you put three full stops in your post.  Youre letting your team down.  :P

                        Not "laid back" but sloppy.
                        I moderate another board and even some English posters struggle to write correctly.

                        For the first couple of years I would correct the worst of it but its become too much for me now.
                        Unless a stand is taken somehow, I fear some of us are fighting a losing battle.

                        By the way, I like this forum because I can write in "strine" and be understood.
                        Much more relaxing.

                          Yeah, sorry Viviane about the full stops! My Dad is a cool guy but a good old fashioned pedant. I love good English, can be at times an academic snob, but try not to worship the vehicle but what is expressed in it.
                          Im also aware that English, like any language, is not static. Even the French with their language academy watchdog havent kept their language pure. The language we have has evolved into what it is and no matter how much we bemoan changes to it, all living things change. The next generation will complain about the generation after it.
                          And come to think of it, I thought the forum was about coffee!
                          (Viviane- from Arthurian legends?)

                          All the best to all

                            Im with you Brett, we just have to worry when the vehicle gets too trashed to express the finer things.
                            Like fully sick stuff, you know?

                            I think the english language takes aprox 800 years to become unrecognzable. (Someone from the 1200s wouldnt understand us)

                              Theres always been so called high and low language- language of beauty and language of use. An interesting thing is that language is a tool to be used and most people enjoy playing with it.
                              I realised what a snob I had become when I was offended by an American journalist using finessed to describe how a guitarist was working subtlely to produce a particular tone. My thinking was the typical Aussie, Bloody Americans!
                              Guess what? While reading Jane Austin I found her using the exact word. So who was the pedant in that case?

                              Have to laugh at fully sick! Those kids will be responsible parents one day- funny isnt it?
                              Some of them might even evolve into coffee drinkers who post on sites like this one!

                              Sorry all for the sermon- by the way todays coffee was smooth sweet and rich.
