Reuben conceived the idea of the first convector radiator in 1925 which replaced the heavy, bulky, cast-iron radiators that prevailed at the time.
Despite the name, radiators generally transfer the bulk of their heat via convection, not by thermal radiation, though the term convector is used more narrowly; see radiation and convection, below.
The term convection heater or "convector" refers to a class of devices in which the source of heat is not directly exposed.
At the same time it introduced electrical convector heaters and panel heaters (ceramic heaters).
These conduction boiler systems use conduction to transfer heat from the water into the metal radiators or convectors.
There are 12 million of all kinds, and we are seeking to cover all new oil appliances, whether of the old convector type or the drip-feed type.
It looks rather like a tubby electric convector fire.
It is estimated that half a million oil convector heaters are now being sold each year in this country.
