Default Distilled Vs. Demineralised Water

Morning,

Is there any problem in using Demineralised Water in a WC loop as opposed to Distilled?

Some HydrX coolant will be added to the water.

Rob.

I thought they were much the same, being non conductive so long as they don't get contaminated? So good for leaks?

Destilled water is evaporated and then condensed.

Demineralised water is passed through a series of resins which remove charged ions, and then a membrane which filters out pretty much everything. It's small enough to filter out bacteria, making it sterile.

The only difference in practical terms is if you are using the water for drinking, in which case the distilled water is better because the evaporation process will remove and/or destroy virus particles. The membranes used for demineralised water are not fine enough to filter out viruses.

Not a good idea to drink either on a regular basis, is it? We need those minerals.

Um... no? I think you've been watching too many Mt Franklin advertisements.

I don't. I think he's right. Particularly, fasting using distilled water can be dangerous because of the rapid loss of electrolytes. The same is true, to a lesser extent if consumed when not fasting. The electrolyte balance in your body is very important to maintaining correct electrical signals, including a little thing like the 4 chambers of your heart.

Demineralised water is for batteries not watercooling.

Demineralized water is fine for water cooling and so is distilled water. Solution should be 10% corrosion inhibitor to water. Make the solution a near full strength corrosion inhibitor to water ratio and you will gum up most of your fine bits including pumps. The result of an overly strong mixture is poor heat carrying capacity and higher system temps.
