dfk41 No problem, it’s not the cheapest upgrade.
The all bells and whistles Ito kit was 257.55 EUR, forwarding to the UK was 23.44 EUR, and then import duty/tax was £60.33. There were a few other bits I needed which I ordered from Germany (this was also a trial run for the forwarding) which cost 30.20 EUR plus 13.45 EUR for forwarding. So in total at today’s exchange rate it was £331.55.
So not cheap, but I enjoy these sorts of projects. The installation is part of the hobby. Electronics projects always add up fairly rapidly to be honest. Hopefully, by doing it myself it gives the machine a longer life too, as I can change/repair anything that goes wrong.
A SBDU machine is perfect for my needs. I especially like that I don’t really have to worry about water, as I live in Oxfordshire, so the water is hard. I use a Britta filter, and descale every couple of months, but the Silvia is so simple that I can take everything apart if needed. Parts are reasonably priced, and even if I have some issues it’ll probably still be cheaper than the running costs of a solution such as an Osmio, or the electricity from distilling.
DavecUK It made it a fair bit quieter, but also changed the pitch to more of a buzz. I wouldn’t bother for sound alone, but I’m not that bothered by the sound of a vibe pump. The only negative I’ve found so far though is that it’s had a big impact on the flow rate. It’s dropped it to ~200ml/min. I need to check this isn’t due to something I’ve done, but I’ve seen others report similar. I’m not sure it matters as that should be plenty for espresso use. It does mean it can take a few secs to fill any air gaps in the boiler, but the Ito shot timer can be set to start counting from a specific minimum pressure, to remove this variable from the counting.
