    Whats the boiler size of the ECM Giotto, CJ?
    A couple of things to keep in mind here guys. A Giotto Premium Plus has the same 1.8L boiler as a Giotto Premium. The internals of the Premium Plus are very different to those of the Premium (piping, restrictors, control board, wiring loom, pressurestat etc)...Neither of these are the same nor are going to perform identically as a modified Giotto pro...Seems to me the respondents to this thread have a examples of pretty much all of these machines *:-?

    Best to compare apples with apples I think....

    WSully if you managed to make all those coffees without a sweat then, as Chris suggests, there is probably nothing wrong with your machine
    yeah CJ, you and chris are most likely correct, it does function well enough to complete the task, as for the temp of the jug, yes i believe it would contribute to the outcome, but the water test doesnt lie,

    Now i just attempted to steam 500ml of water (tap) in a 1lt Jg using the Giotto, the pressure dropped from 1.2(idle) to >.5 and it only got to 67C
    And that was tap water, room temp jug.......

    Caution--rash speculation and inappropriate comparisons ahead!--

    Im going to say that I think Warren has an issue, whether it is an issue in real practice I cant say.

    However,--

    I just steamed 500 ml of water to 80°C using my machine. The pressure dropped from 1.05 bar (idle) to .6 bar.

    Now, I wouldnt want 500 ml of milk that hot, and that much milk would do about 8 of my standard piccolo lattés anyway, so Id probably never do it.

    But I would have thought its steaming capability was very similar to the Giotto. Anybody out there with a Giotto prepared to do the test?

    Greg

    i just did it, and from 1.2 it went down to .8

    i didnt get a chance to do the 1 ltr of milk on the weekend, but i will do 1 ltr of water from the fridge now in a 2ltr jug and see how i go.

    Do you have a reliable thermometer in the fridge? Fridge temps are notoriously different to each other and commonly, too warm. ;)

    Re: Giotto steaming question

    cold water test out of the fridge
    1ltr of water 2 deg and got it to just under 70 deg before i hit .5 on the gauge.
    Stopped it there.
    The pump did kick in but no issue with steaming power whilst the pump was going

    so, i doubt id be able to take it to 80, but i never drink coffees that hot anyways.

    this is with around a 5 year old giotto premium

    so 500ml of cold milk should be done with ease

    now its time to go make a real coffee and stop playing with water :)

    i just use the thermometer i use in the jug, this way at least i can tell you from what temp to what temp on the same thermometer

    Re: Giotto steaming question

    I dont think further tests are necessary. Chris is right and we should acknowledge to ourselves that we have a great domestic espresso machine that makes excellent coffee, but preferably two at a time.

    It seems it is possible to steam 500ml or even 1 litre of milk but I dont envisage having the need to prepare that much milk in one steaming and I dont think I will be pushing mine that hard.

    Still, good to know.

    cant argue that. This is why i still have it and have not thought of changing. Well apart from a lamarzocco GS3 along with a mazzer robur

    With a machine like this you shouldnt be pulling more then two shots (split double) before you steam. The machine should keep up if you pull a shot (split double) - steam for two cups that have just been pulled - pour the milk then pump out the next shot - steam etc.. Doing it this way wont slow you down at all and has the added benefit of your guests getting fresh shots/milk (no shots sitting around for 1-2 min). You should also steam the milk for Hot Choccies separately, unless of course someones milk drink is using a double shot base.

    Hell even most three group 18+L HX machines cant run the steam wands continuously - they need recovery time (not much only a couple of seconds but it is needed none the less).

    what about the manometer? Does it drop?
    Yes the boiler pressure guage does drop, generally down to about .6 or .7.

    Seems like you are finishing on a somewhat low note Warren. Is your glass half-empty?

    You might want to go back and review this post . Yes, Chris mentioned that the thermostability-upgraded GP may have more steaming-oomph but note Renzos comments on the GPP discussion thread:

    - It also stood remarkably well our dinner party test: private event on Sunday in our store had the GGP alone catering for 30 coffee lovers pumping lattes in a chain,with the normal purging, not even once weve had to stop for recuperation or open full steam to speed up dry steam build up.... *
    Sit back and enjoy your coffee in the knowledge that you have spent wisely. Dont keep looking on the other side of the fence. *;D
