The surrounding wall and a fireplace are on the same plane, and the niche is behind the hot air stream rising above the fireplace. This option can look beautiful when done correctly, but it is harder to build. WebThe mechanism responsible for the rising of hot air is flotation: Hot air is less dense than cold air and hence air pressure will exert an upwards force, in the same way air rises in water. Now if cold air was magically unaffected by gravity, then it would not be able to exert pressure on the hot air and thus it would not rise.

WebFeb 11, 2016 · The common explanation is that hot air has less density than cold air, and consequently, it rises. Fair enough, the hot air will end above the cold air, but why is it rising in a column? With the same argument, I could deduce (and I know that it's wrong) that the cold air above is denser, so it will go down, pressing the hot air away sideways.
