Distilled or Deionised Water?

post #1 of 19
Thread Starter 
Ok ive been looking at this in some detail as im currently making up a watercooled rig.

From what i have read on the internet people say deionised is bad for cooling as it takes ions from the waterblocks and can cause damage.

Here in the UK as far as i can see Deionised water is more common and cheaper i believe, from what ive found anyway, so is there really that much of a problem as i also see people out there who have run it for years with deionised and never had a problem.

BTW: yes i will be adding additives to the water.

This page has a pretty good run down on DI water..DI Water..Long story short its OK but offers no advantage over straight distilled, but if thats what you have I'd use it...

Dionised water can [and most likely does] contain organic matter like bacteria. I think it's ok to use in a loop with PT Nuke.

Everywhere sells distilled water. Check out the bottled water section of your supermarket. Look for ultra pure water or something to that effect. I found my 2L bottles of distilled water there.

UK supermarkets don't sell distilled water as far as ive found.

If your still at school your school's chemistry department will normally make its own distilled water, so ask your chem teacher nicely if you can have some.

Failing that and you dont want to buy it you can always make your own. Do things old school Its pretty easy to do, although when ive tried it takes ages to any kind of quantity.

I use De-Mineralized water that is then run through a De-ionization process.

And it does cause the water to want to return to an equalibrium by stripping copper from the blocks in the loop, so I add PT-Nuke since its primary ingredient is Copper(II) sulfate pentahydrate (CuSO4·5H2O).

It would take a gazillion years for solid copper to be dissolved in water so don't worry about that.

If you can't find distilled water, grab some deionised water.

I dont know about copper but the aluminum heads on your car is eaten by your coolant. This is caused by different metals in the cooling system, that then causes a galvanic battery(2 dissimilar metals in the presence of an electrolyte). If you have a copper block and an aluminum radiator this may be the same thing.

So what I am saying is just run distilled water and additive and change every year or 2.

BTW: I have changed many radiators that have copper cores that are eroded thru, but they are also exposed to the elements.

Edit: When I say changed radiators I mean in cars I am a mechanic
