Welcome to AFF,
JasonD. Nice to have you on board (pun intended).
Thanks for your response, too.
It's interesting you mention this. If I recall correctly, most cabins are pressurised to 8000 ft equivalent above sea level (i.e. about 2500 m above sea level, which is where some of the highest towns and cities in the world are located). As water boils at different temperatures as the ambient pressure changes due to altitude, at a height of 8000 ft, the ambient pressure is about 75 kPa (ref: on the ground is about 101 kPa) and thus water boils at 92 degrees Celcius, not 100 degrees.
Of course, the boilers on board may be special ones which may be locally pressurised so that water boils at 100 degrees in them. Furthermore, I know boiling kills most bacteria etc. (they recommend this as a first pass action when dealing with water of questionable quality for drinking); I'm not sure if 92 degrees is low enough that some key bacteria would not be killed in boiling action, but I'm prepared to go out on a limb to say it would still be sufficient.
