Interesting. We use demineralized (DI) water at work. It is made using hydrochloric acid and caustic, essentially a chemical process.
Distilled water is the same (demineralized), it's just 'made' differently, using heat to 'evaporate' and seperate minerals from the water.

The Distilled water co. sells both distilled and demineralized. You just order which you want cheers Kirsteen On 9 Apr 2015 00:11, "Neville" <one.red...@hotmail.com> wrote: I know nothing about making EIS using Demin, RO or Deionised water, but a person in the UK wants to make some EIS. Apparently the only water available in the UK are those mentioned above, is it OK to use this water for making EIS? I would be thinking it's OK, it will just take longer to brew a batch perhaps. I don't think a home distiller is an option here either. Thanks N.
