WebConvection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow ). One advantage that is peculiar to all types of convection heaters is the ability to heat the whole room. This has made convection heaters a good choice for places where people are likely to spend more time … Meer weergeven As the name suggests, a convection heater uses convection currents in its operation.
