How Does a Convection Radiator Work

In a convector radiator, the hot water is circulated through a tube, surrounded by small fins. These fins act to increase the contact surface with the surrounding air. As with a regular radiator, the hot air rises up and attracts cooler air to the appliance.

Is a radiator convection or conduction?

Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation.

Are convector heaters expensive to run?

According to the Centre for Sustainable Energy, a 2kW convector or fan heater will cost 28 pence per hour to run; a typical 1.5kW oil-filled radiator will set you back 21 pence per hour; while a 1.2kW halogen heater costs around 17 pence per hour. Gas is significantly cheaper.
