Sorry, but that is not true. I too used to think of distilled water as
being neutral, but, "pure, distilled water is highly corrosive and will
suck up metallic ions like mad.
Water is one of the best mediums for heat transfer, however, tap water
would work well in a SS amp with the heat sink/spreader at chassis
ground potential. Tap water would not wok in a tupe amp where it has to
cool the anode of a tube at a high potential.
I worked with this stuff (DI & Distilled) for close to 20 years.

If the water being distilled has corrosive contaminates whose vapor pressure is greater than water, then the distillate will have them too, but since the VP of water is already higher than the mineral salts that are the typical corrosives, the most likely contaminates are organic.
