Distllled Water

Most places don't actually sell distilled. Its normally di-ionised which is fine but uses a different method of purification.

Tescos also sell di-ionised at about 70p per litre.
 
If you want distilled instead of the more readily available de-ionised, try a chemist shop.

I last bought some about 18 months ago, my local Boots didn't stock it but ordered it for the next day, was about £5 for 5 litres.
 
Wont deionised water react with any coolant? Isnt there a chance it will also have a corrosive effect with any cpu block?
 
Nope, boiled water is basically what it is, its boiled then the steam is caught on cold surface and condenses and runs back into container and you have your Deionised Water

Now im confused.

Whats the difference between distilled and deionised water?

And sorry, i read deionised water as ionised water and hence made the corrosiveness comments. But of course ionised water is actually just dissolved salts rather than actually creating ionised hydrogen/oygen molecules in which case itd cease to be water.

Deionised water shouldn't be used because it will try to rob ions from any source it can, waterblock,radiator.

Another potential concern is that DI water is more corrosive to metal parts than plain old ionized water. It takes a lot of effort and energy to remove the majority of ions from water. Water desires these ions back and will aggressively take them from any available source. Some people will tell you to never use DI water in a PC water-cooling system. Like most things in life, moderation is the key! If you use DI water to occasionally fill your cooling system, the water will immediately strip ions away from the surfaces of all wetted metals. But, no measurable damage will occur. You would have to continuously fill and drain your system 24/7 for weeks before you might see your waterblock or radiator starting to dissolve. Truly pure, DI water doesn't stay de-ionized very long when exposed to air and poured thru various containers

Been using di-ionised water for years here. I've yet to encounter any problems. If di-ionised was so bad and corroded any metal it came into contact with then I'm pretty sure it wouldn't be recommended for kettles and car batteries etc.

Correct, batteries, irons etc etc.

We used Tap water up here for the batteries and Rads but in England they couldnt as of Lime etc.
 
If you are using distilled/de-ionised water, isn't adding something like iodine recommended to prevent anything growing?

If this is the case, how much do you need to add?
