Thank you for your question
The Aga Little Wenlock classic stove is a radiant stove.
Convection stoves typically have extra panels around them that draw in cool air behind the panels, it is then heated between the stove and panel and leaves the top of the panel as hot air that helps warm the room more quickly.
