Oxygen Not Included Best Heat Transfer. This is the tricky bit. Guideworking with the game files.
As all materials have low thermal conductivity small differences can impact heat transfer greatly. Solids in general at least metals will tend to shed or gain heat rapidly regardless of medium theyre touching. Ice maker which deletes 20 of the heat in the water it cools and releases the rest into its surroundings and further.
Solids in general at least metals will tend to shed or gain heat rapidly regardless of medium theyre touching.
Materials are listed in ranking from best to worst. Anything under 750 g of gas and youre wasting your time. It is also unbreathable for obvious reasons. At the wall section it would transfer a very minor amount of heat with the insulated wall using its heat conductivity value and finally with the cold hydrogen on the other side of the wall essentially.
