[RE-wrenches] Thermal storage water stabilizer

[Jeff Yago]

Distilled water is distilled water, not hot water.  Distilled water comes
from water boiled into a gas, then the gas is distilled by passing through a
cooling coil or heat exchanger, and when this gas turns back to a liquid it
is distilled water.

Commercial water distilling systems use either glass or stainless steel
piping because pure distilled water is very "corrosive" to many piping
materials.  If I leave several plastic gallons of distilled water around for
long periods they usually start to leak out.  Not sure if that is eating a
hole in the plastic or cheap plastic, but you will not get distilled water
by just heating, it must turn to dry steam (gas) first.
