    Thanks for reply Blend,

    is there some more info somewhere and source etc? Where can I buy them? Are they easy enough to install?

    How do they work, by letting lesser amount of water passing through head, so not heating the head to high(er) temps?

    Sounds very interesting.

    TIA

    I just got a second hand TEA II and was wondering about the flushing/cooling

    Some view the heat profile of the unrestricted E61 thermosyphon ( as fitted to the Tea), as a way of setting the ideal brew temperature to suit a variety of different coffee beans. . Even if that is of no interest to you, the normal procedure of a quick flush to "set" the temperature, is quickly learned and becomes part of the routine.
    Also, if you feel competent to install a PID, then fitting a restrictor should not be an issue to you. ?

    I always flush, it just brings the temp down although id like to look into fitting a PID to mine to help keep it constant, but in saying that its no bog deal-just fill it up more often!

    Thanks all. IF it is the v1 and I need to have a restrictor added (whatever that is) then I might just PID the silvia and see how I go with that for a while, then I think I'll save up the dollars and get an new ECM technika.

    I had the overheating problem with my Tea II when I purchased it from a large concern in Perth but the boys at Dimattina in Perth added a restrictor when servicing the machine for me and now she is able to stand for hours with a stable temperature.

    I thought that the machines were now configured for this market and that they had worked on cooling flush. Still no restrictors?

    If it's still the case, and declaring my professional interest, I'd recommend the VBM Domobar Junior instead. No cooling flush required and superb internal build as well. Worth the extra $$$ IMHO.

    It will require a cooling flush, maybe 100ml to take the overheated water out of the heat exchanger. Once you get the feel for the machine, it is easy enough to get right over and over. I tend to run water out of the double handle and wait for it to pour without spluttering, then grind, lock in and off you go.

    The Tea is nice machine without being too big, you won't regret it

    The Isomac has an E61 group with a heat exchanger, completely different setup to the single boiler Silvia. From what I understand the brew temp of an E61 group can be tweaked with boiler pressure and thermosyphon restrictors.

    The Isomac also allows you to use steam at any time which is handy when making a few coffees. And the E61 looks sexy!

    Cheers

    Isomac Tea Due question

    HI All. Quick question. I was about to PID my Sylvia when the option arose to buy an Isomac Tea Due, used but great nic. I'm a bit of a technical novice and wondered whether I would still have an issue with water temp with the Isomac? What I mean is, I currently temp surf the Sylvia (hence the purchase of the PID), would I still need to do this with the Isomac? Cheers, Steve.
