Gino, I have a question.  If there are more minerals disolved in
hot water, they must come from somewhere?   Given that every
water heater I've ever had has died due to DEPOSITS of minerals
in the tank (despite careful and periodic flushing), it seems
to me that the net flow of minerals in my tank is positive, in the sense
that they come into the tank, and then precipitate into the tank.
Given this, I propose  that there cannot be MORE minerals in the 
hot water, since one has (input minerals) - (minerals deposited)
coming out of the tank.  <The tanks don't seem to be dissolving, and that's
the only other possible source of minerals...>

Now, then, all of the dissolved air is generally eliminated,
mostly (I understand) by reaction with other disolved minerals,
thus leading to FLAT tasting water.  This is the reason MY mother 
always gave me for using cold water.  It also shows why that
pouring the HOT water through an aeriator and letting it hit the pot
hard also seems to make tea taste better.
