You are aware that the relative thermal conductivity of copper is 225.
Silver is 250. Stainless is 6 to 8, and aluminum is 175. You can use
stainless. Lots and lots of it.

Stainless is used, not because of any thermal conductivity, but because
it does not leach metallic salts and corrosion into the drinking water
it's making, making that water taste like battery acid. Stainless has no
trouble, whatsoever, getting steam to drop in temperature below 212F, a
huge temperature differential to air temperature. The water has no
metallic dissolved salts in it.
Distilled water is quite corrosive because so many things will REALLY
dissolve wonderfully in totally pure water. It dissolves many gasses
right out of the air it naturally touches if you leave it in an open
container. It dissolves whatever is making your refridgerator stink into
itself in a matter of minutes! The use of polyethelene white milk jugs
even makes it taste awful. Polycarbonate (those really clear plastic
bottles drinking water comes in) is best for storage....completely sealed
from outside air intrusion.
When you're showing someone how insulating, electrically, distilled water
is with a high voltage tester, what's fun is to drop ONE GRAIN of table
salt as far away from the probes as possible into the water...ONE GRAIN.
The tester will immediately jump right off the scale. It's amazing how
fast NaCl ions can travel through distilled water across it.
