I know, it makes you want to scream.
A fan heater is good for heating a bulk area quickly - within the limits of the heater. Hilarious reading reviews of people trying to heat a "warehouse" with a 2kW heater when even a big propane heater has a job.
An oil filled radiator is good for creating a local hot spot, particularly under an enclosed desk.
An aluminium extrusion radiator is good for mounting solidly on a wall and resisting "traffic damage" whilst looking very attractive in "side view". I needed a backup heater on the stairs, but due to "eyelevel" location everything else was pig ugly. The bottom of the range 700W Calortec F.Prime with various vouchers & offers was =A3120 which was =A335 more than the cost of the extrusions for a plug, thermostat & element. For comparison Elnur is about =A3230 and it goes up from there.
