A little science heat ques... Easy Best Answer?

Question

what heat transfer does an electric heater use?

by the way electric heater has vents from the floor...There are 3 types of heat transfer convection, conduction, radiation...

Answer 1

A glowing bar heater is radiation.

A heater that does not glow but has vents at top and bottom will be convection.

And sillyest of all a radiator uses convection despite its name.

But the heat in the water inside a radiator gets to the air through the metal by conduction [through the metal] and then by convection through the air.
