    Nem biztos jó ötlet a becsatlakozás az áfa miatt. Ha magadban rendeled, akkor 34 eur, ha ketten, akkor rá fog jönni a 27% áfa és máris 36 eur lesz darabja.

    DJBoris, Kzoltann, Bazsee71 - köszi a tippet! :)

    Rácuppantam a vizes témára és ezt a rendkívül informatív leírást találtam Jim Schulman (nagy kávéguru a külföldi fórumokon) tollából:

    Gaggia kisgép tulajoknak külön is kedveskedik egy összefoglalóval korrózió és vízkő ügyben:

    A Water Treatment for Gaggia Home Machine Boilers
    High alkalinity and low hardness water protects a Gaggia, since the alkalinity won't be reduced by scaling; while low alkalinity, high hardness water is deadly, since even if the original alkalinity is above the 50 mg/l safety limit, it will scale out, making the water and steam corrosive [section 1.8]. This leads to the following recommendations.
    For those who are willing to be painstaking: 1. Use good coffee water (see above) 2. In the presence of calcium, steam temperature will reduce the alkalinity to a corrosive level. If you are using very high calcium water, even the brew temperature can reduce the alkalinity to corrosive levels. Therefore, after every espresso making session, flush the boiler and immediately turn the machine off. Descale on a regular schedule as explained above.

    For those who want it foolproof at the slight expense of taste: Start with hard and high alkaline water (higher than 50mg/l), then soften it with an ion exchanger. The ion exchanger removes the scaling calcium and magnesium, but leaves the high alkalinity intact.
    If you use a small ion exchanger connected to the machine's hose, don't forget to recharge it weekly. Avoid the Brita or Pur jug filter for this, since their use of hydrogen ion replacement makes the water slightly acidic, and leaves much of the calcium in.
    If you have very soft water, or an RO system in the house, add a small pinch of baking soda (sodium bicarbonate) to every liter of water when you refill the tank. This will not be tasteable, and will supply about 70 mg/l of non-scaling alkalinity, more than enough to protect the boiler.
