The product description looks like it was written by Google's 
Translation tool.  "Through a reverse osmosis and mixed bed facility is 
also demineralized water. "  WAT????

Actually, it would be.  Gas bubbles have a very different heat transfer 
coeeficient and will act as an insulator, instead of a conductor.

If it contains an additive, is it still "very pure"?  Also, the bottle 
says that it is NOT an anti-corrosive agent, and that it should be mixed 
with one, preferably their own, of course.

Overall, I'm getting a bad-vibe from this product.  Just like when 
reading the description of audiophile gear.  Especially when you factor 
in the deep barytone voice that says "Feser aquaaa.  Ultra puuurrrre 
Waterrrr" when you visit their web site.
