Natural Draft Convector
If there is no fan to pull the air in, fresh air must come into a convector heater from below. It is drawn in because the air heated by the heating element is warmer and therefore lighter than the colder air below it. So the warmer air rises to leave the convector heater from the top.
Convector central heating radiators can be purchased from many different stores, online and offline. Some examples of these stores include Plumbworld and BuyARadiator.
Convector heaters can be purchased from many shops, such as Wal-Mart. Local independent electrical shops will stock these appliances also, as well as being able to be purchased online.
