Convection heating

When radiators heat the air of a room we achieve convection heating, this generates a convective stream that rises and touches the objects to which it gives heat, as it cools down it falls back down to the ground and the cycle starts again.

As we all know this system causes currents of dry air which carry dust and bacteria.

It is not so much the heat (energy), but the hot air that rises, therefore the convection system produces hot air at the top and cooler air at the bottom.
