What is distilled water?

no that is condensed water....

Yes. Works great for rads and batteries.

Distilled means collected from the air, don't know what condensed water is, maybe 'heavy water' they use in the nuck plants?

I mean it does have a cold coil to 'condense' water out of the air at a certain temperature, but so does a liquor distiller. They have coils to 'condense' the alcohol out of the air at a certain temperature.

It should be pretty much (well, if you don't count any mold, dust, or other contaminants that may have gotten in there..)

As for what it is, it's just water that doesn't contain any dissolved salts, minerals, etc, just pure H2O..

Condensed steam.

Water out of a de-humidifier can potentially be distilled but more than likely a de-humidifier will also attract dirt and other foreign objects that float in the air with the water vapor.

Distilled means to separate or purify... Like another poster said, it's pure water. One way to get pure water is to allow it to evaporate into vapor and then let the water condense back into liquid form. Another way is to filter all the impurities out of the water.

I used to make distilled water a long time ago when I was in chemistry class. Here's a good definition of distillation, the process used to get distilled water.

dis.til.la.tion

Pronunciation: (dis"tl-A'shun)

-n.

1. the volatilization or evaporation and subsequent condensation of a liquid, as when water is boiled in a retort and the steam is condensed in a cool receiver.
2. the purification or concentration of a substance, the obtaining of the essence or volatile properties contained in it, or the separation of one substance from another, by such a process.
3. a product of distilling; distillate.
4. the act or fact of distilling or the state of being distilled.

For automotive uses, the water that is produced by a dehumidifier should be fine. Just make sure no foreign objects i.e., insect bodies, have gotten into it.

For all (automotive related) practical purposes, yes. So is rain water, but that just picks up more pollution on the way down...

I use de-humidifier water all the time in cooling systems.

If you mean the typical bottled drinking water, that's not distilled. Some of it is just municipal tap water or well water with a nice natural looking label. E.g.,

No. I mean the distilled water elsewhere in the same isle.

Most stores have both. One jug goes on the shelf with the fluids, the other in the frig with the beer

Deioinized water is the same as distilled water (it's made differently) and so is water made by reverse osmosis.

cheers

Actually it is not. Common misunderstanding.

Distilled water is first boiled to steam, which leaves pretty much all mineral content behind. Also leaves behind most of the organics, depending on how the still is set up, those with boiling points much higher than 100C. Can leave behind even more, but for anything but a chem lab, why bother. Fairly cheap process.

I am not going to read all the replies, or go into a missive about distillation techniques etc. However, do a quick google search on "distilled water". I found a succinct definition (plus a bunch of blatant advertising" at

- it seems to be some firm flogging (sorry, I mean advertising for sale) water distillers.

Hope this helps.

Sure it will. You can't ionize or filter out minerals. There is a very big difference between filtering and distillation. With distilling you remove the mineral content (which is what is 'bad' for the cooling system). Your cooling system does not care how the water tastes. It just doesn't want all the mineral scale buildup.

I had a hell of a time keeping my cappuccino machine from clogging up (we have hard water). Since I've started using distilled water I've never had to clean it. BTW: any company who sells you ionized water and calls it distilled oughtta be sued. There's no substitute for distilling when it comes to removing minerals. Unless you are actually combining H and O2 to make it pure.

A water softener removes minerals... but it replaces them with other minerals (usually potassium salt or sodium salt).

It's not "ionized" water - it's "deionized" water. A deionizer removes minerals, or it should, if it's not exhausted

I'll have to check that out. Thanks!

Very correct.

It depends what you want your treated water to do. If you don't want mineral scale, you remove the scale forming ions such as calcium, bicarbonate or carbonate, sulfate, silicate, magnesium, and others. This may also help the taste of the water. (Strangely, some really heavily mineralized water sometimes makes excellent coffee)

One would hypothesize that distilled or deionized water would also be less corrosive than water containing minerals. Not necessarily so. Sometimes distilled, deionized, or RO water can be quite corrosive. Corrosion inhibitors, or mineral additives, are sometimes added to certain systems to reduce the corrosive attack..

Mist from a humidifier might well not be the same as distilled. Some of those things just fog water droplets into the room. The heated units we call vaporizers in the USA actually do distill the water, and if you set up a rig to capture the condensed vapors in a glass or plastic container, you would have fair quality 'distilled' water.
