What size copper tubing should I use for a water distiller?
I'm difficult to make my own water distiller, and since copper is not heat conductive, this would be my best substantial to use in order to collect water vapor and transfer it to another container.
Copper is very fieriness conductive.
A water distiller coil collects condensed steam as a bright, not water vapor as you state.
Unless you are after a lot of volume, use as thin a tubing as you can find that will still permit water to flow through it. Perhaps 1/4 inch ID?
