    Silva users...info please

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all,

    Thinking of buying *Silva/Rocky combo in the next few months; still reading as much as I can.
    I will most likely be drinking 4 to 6 cups daily.

    Do you Silva users leave the machine on all day or just turn it on when required?
    Does turning it on and off deteriorate any of the seals or the machine in anyway?
    If left on all day is there a large power bill involved?

    Was in a shop "looking" around a few days ago in Melbourne and the chap said that with ECM Giotto
    there is no need to turn them (giotto) off 24/7; this stops seals and the likes from breaking down and
    there is negligible cost in electricity........any reliable info from users here?

    cheers,

    kopi

    From a machine point of view he is right.

    From an insurance liability point of view - if your house burns down because of a kitchen fire - your insurance company are going to go over the remnants of your kitchen appliances with a fine tooth comb, better to turn off.

    You can run either machine off a timer - just dont leave a pump button on or the water tap valve open.

    I tend to turn the machine on first thing in the morning, take a shower, use it and then turn it off if Im going to work/uni or leave it on if Im staying at home. I like to give it as much time as possible to warm up and would argue that leaving it on overnight will give you better shots in the morning ... except that thats a ludicrously small part of the equation!

    Power consumption-wise, I dont have the figures for a Silvia, but something like a Cimbali Junior apparently takes up the same amount of energy as leaving a lightbulb on ... so youd expect the Silvia to be less. Kinda makes you appreciate how much energy it takes to light up a room!

    Cheers,

    There is nothing to be gained from leaving it on all day. It heats up nicely in 30 -40 minutes. Pull the shot, flush out the grounds and switch off.

    Constant heat cant be good for seals.

    Electricity consumption, however, will be miniscule, given that most of the time its on stand-by and not actually heating.

    The heating cycle is 50 seconds on....and then several minutes off. The power used in 50 seconds is about .2 cents (point two cents--not two cents) where we live in Melbourne.

    As Luca said you can use a timer, i grabbed one a month or so ago and its most valuable. i went for the timer with the push down keys instead of the timer that uses pins.

    you can turn it on and off.... on and off... all day in 15 minute blocks if you wanted.

    I used a silvia with a mazzer mini for a good 3-4 months. I found that you could get a decent shot within 15mins of turning it on by flushing a couple shots through first before you pull your actual shot.
    I was told by the sales person at mocopan that it deteriorates the seals if you were to leave it on all day - I think this is limited to the Silvia and machines like it.

    Re: seals ... not too sure what the truth is on this one. Remember that if you turn the machine on and off a lot, the seals will expand and contract a lot, which, I would imagine, would be more stress than just leaving the machine on.

    In any case, I think that its more or less a moot point. I bought a spare grouphead seal for the princely sum of $8 and after two years of fairly heavy use it is still sitting in a drawer somewhere.

    Cheers,

    Luca

    Just to point out.... i do not do the above!
    my machine is set to turn on at half 5... and turn off at half 8 each morning...
    coffee at any other time is done through the over-ride switch and a 30 minute warm up.

    The Silvia is such a good brass heat sink. I turn it off after the morning coffees are done with and turn it on again maybe 2 hours later for the next round. Because its pre-warmed it only needs about 10 minutes to come up to temp the 2nd time.

    The key to seal longevity is ;
    [list][*]Keep the grinds off the top of PF where it contacts the seal when fitted.
    [list][*]After the shot, always wiggle the PF when rinsing.
    [list][*]Keep the PF fitted but not locked when not in use.
    [list][*]When you clean the shower screen, clean the seal, using a proper group head cleaning brush. An angled toothbrush might get you out of trouble but use the right tool for the job. Dont be tempted to just have a scrap with a kitchen knife.
    • Inspect the seal regularly, I use a small mirror and a torch. Someone mentioned they flip the machine upside down, too labour intensive for me.

    Yeah, good point. Seeing as Im probably the only person in the world to fit a thermometer to the boiler without installing a PID controller, I guess that I should get off my butt and actually do some research on this.

    *goes and checks machine*

    It has been off for 15 minutes or so and the temperature, as read with a standard digital thermometer at the TOP of the boiler, is 92.7C. The machine has been on for, something like 14 hours.

    Cheers,

    Luca

    Actually, when I had my silvia - my brothers got it now; I had a thermometer installed with a digital readout. The PID sounded tempting, but I never got round to it. Anyways, now thats history, my office pulsar is on the way :D
