That’s just not true. Heat moves along the path of least resistance, not “up,” “up” just happens to generally be less resistance than “down” due to density differences in air.
heat is atom speed and electricity is electrons jumping
From your second link:
In other words, heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from one atom to another.
Density matters. Free electrons matter. But in short, metal and water conduct heat better than air, which means the heat transferred is more likely to go into the water than into the air. Certain metals conduct heat better than other metals, largely due to electrical conductivity.
