Abstract
A heater assembly to be located at a substantially vertical wall for heating air. The heater assembly includes one or more heating elements, and one or more heat transfer elements mounted on the heating element for transferring heat to a column of the air moving substantially upwardly past the heat transfer elements. The column includes an inner portion positioned proximal to the wall and an outer portion positioned distal to the wall. Each heat transfer element is formed to transfer substantially more heat to the outer portion of the column of the air than to the inner portion thereof, to cause the outer portion to rise faster than the inner portion, for at least partially entraining the inner portion with the outer portion, so that at least a part of the inner portion forms a laminar boundary layer flowing along the wall.
