  • Startup (elec) costs for a 2-group commercial machine.

    So I'm looking around for a (relatively) cheap machine to tinker with... among the available options is a two-group Boema - looks like a Deluxe with volumetric functionality, for $550. Appears to be in good nick though I won't be able to check it out for a few days and would only know the bare basics to look for.

    Anyone care to talk me out of it? I'm seriously considering it, bar what I've heard it takes to get something like that up to temperature (a couple hours at what, 3600W?).

    What's the total load for a startup on this kind of kit? Are we talking full load until it's up to temp or is it not quite that bad?

    I don't know if its worth doing a search but there used to be quite a good thread on costs of running a commercial machine in a domestic situation. Can't remember where it would be or what it was called though.

      Cheers SG, I'll have a search around. As an aside, any idea if the price is right?

        Just insulate the boiler and turn it off after last coffee of the day, back on a few hours before first coffee in the morning. Electricity costs won't be that bad. 3600 W element, heating what 4 L up to 1.2 bar won't take long, then 12 hours with the heater duty cycle say averaging 10% wouldn't be much more than a $1 a day. The time getting to temperature will be the real headache.

        I'd be more concerned with part availability given it's second hand and probably pretty old, and availability of service manuals and wiring diagrams if you want to tinker.

          G'day D'21...

          Here's a link to a thread that explains it well enough... http://coffeesnobs.com.au/off-topic/...lculation.html

          There used to be a Sticky at the top of the Extreme Machines category but it's disappeared unfortunately.

          Mal.

            Dragunov, my honest opinion is I'd give you $50 bucks for it but even then I'd have given you too much for an old Boema. I can remember that we flogged off an old Brasilia Portofino for about $600 a few years ago and it was a goer. So maybe you should have a bit of a look around and see what other gem might be out there. Just my opinion!

              Have you noticed the 2 group La Pavoni for $400 that popped up for sale today? Are you looking at the boema in west perth with the grinder?
              I was watching ebay and gumtree for a few weeks before I picked up my Bezzera. Quite a few semi commercial and commercial machines came up in the $500-$1000 bracket. I had mine shipped from sydney to perth for $50 (20kg).

                I might have paid $50 for a Boema too, but only so I could take out my frustrations on it with a sledgehammer..........if you've ever had to rebuild a Boema tap, you'd understand why. An unnecessarily complicated design that appears to allow for careful adjustment to reduce freeplay in the mechanism, but doesn't actually work due to poor design of the components - similar to some Gaggia taps. And too many other parts of Boema designs are quite antiquated.

                These days I wouldn't buy a Brasilia either, they have their own minor issues but the biggest one is now the difficulty of sourcing parts since Brasilia is now defunct.

                  Thanks Dimal

                  SG, how old is old? I thought from appearances it looked alright, but then I don't know what I'm looking at, really. Getting model/man. date/service history off the guy soonish... or am I just wasting my time?

                  I guess I figured that if a single-boiler domestic was worth 200-500, a commercial E61 HX would be worth more :S

                  Might keep my eyes out for something else. Any hints on what I should be looking for?

                  That La Pavoni looks like a busted-ass version of the Boema I'm looking at - is there anything to recommend it over a (presumably) in-good-nick Boema?

                    Quite a few BZ99s and BZ35s have been popping up on ebay lately. One went for $350, mine was a little bit more.

                      Well, it looks pretty tidy actually and it seems to have touch pads rather than buttons. So it might not be too old.

                      Boema's are kind of like the Holden Commodore of the coffee world. Well, that's how I've always seen them until I saw a couple of their lever machines. It is almost like the transition between lever and semi automatic meant coffee machines lost their soul somehow.

                      Don't let us squash your dream to own a machine, at what ever cost! I mean, I bought a 2nd hand Elektra for a fair bit more money however it had been restored and then some. But I didn't want to tinker with a machine and I also didn't want to settle for a Commodore when I could have a Ferrari...

                        Well that's the thing; it's not a dream, it's that if I can pick up a bargain commercial to spanner on with (and practise on, since I've discovered working on a commercial is quite different to my Classic) then I will, but half a grand is about all I could justify (and mebbe a few hundred more on parts if required).

                          do a ring around of roasters in your area, older machines that get pulled out of accounts often sit in the warehouse unused. if you pay cash and don't ask questions they can't answer, chances are you'll pick up something reasonable. A cursory check inside and out should be all you need to figure out if it's a go-er.
