What is distilled water?

Is the water that comes out of a de-humidifier distilled?

I've worked at a couple of places where an Innowave distilling machine was leased. The first time, I swear the water tasted like plastic and metal. I think it was a new machine, and the taste of the new materials was probably leaching into the water.

The one at my current workplace tastes just fine. It's cheaper than the bottled water that used to be delivered. Sometimes people forget to drain the boiler tank when a light goes on. It stops distilling at that point. The stuff that comes out of the boiler drain is a deep yellow color similar to another common yellow liquid.

I've actually used a small amount of this distilled water to top off my coolant overflow tank.

Nope, again.

'Getting it back into the air and de-humidified several times' is mumbojumbo.

Now, you may KNOW what you wanted to say, but you sure as heck didnt manage to say it.

Well, one is a dehumidifier. The other is an evaporator. Similar, but different.

They don't grant EE degrees like the one you claim to have unless you have a grownup level of literacy.

What else are you lying about?

I dunno. Some of my foreign teaching/lab assistants at UC Berkeley couldn't easily converse in English. Primarily the ones from China. The TAs from India were fine except some had very thick accents.

I don't quite understand what you mean. Be careful of the Legionnaire's Disease in the dehumidifier.

Water which has been condensed from the vapor in air, as in a dehumidifier, is basically the same as distilled water as far as soluble mineral salts are concerned.

This water will be saturated with gases such as CO2, oxygen, nitrogen, etc in equilibrium with the air.

It can also be contaminated with dust and other particulate matter from the air unless special care is taken to exclude it, and it may also become contaminated with metal ions from the heat exchange surfaces in the dehumidifier.

SO, it won't be pristine conductivity grade water, but it will be purer than dipping in out of a creek.

I remember some building in Richmond, California that had an outbreak of Legionnaire's. It was growing in the HVAC system. The solution was to wipe the system components thoroughly with Cascade diswashing detergent, which at the time contained chlorine bleach. At this time, they'd probably uses straight bleach or some other disinfecting product.
