Used for approximately 18 months, using triple Everpure filter system, in addition to water softeners. No calcium/scale build up noticeable at all. It was properly drained immediately prior to storage. It is now in heated storage in Burlington area, VT.
If you are unfamiliar with these machines, they are, in my opinion, the best you can get for many applications. They can be tailored to your own brew specifications on many specific variables without being convoluted. You can brew continuously without delay. Impressively consistent results, and some safety features which can be removed for experienced users. I would personally be happy to help you learn how to use it and program it properly. The original manual is also included.
Pics soon, if necessary. Alternately, just email me and I can send pictures if you'd like. It's practically scratch-free, and very clean.
