whether one type of electric heater is more 'efficient' than another!
As several posters have said if several different heaters each consume say 3
kilowatts and you switch on/plug in any one of those heaters, so that it
runs continuously for one hour, it will use (and cost you) 3 kilowatt hours
(or 3 units) of electricity.

Energy out vs energy in gives you 100% with radiant, convection, and
fan.

Energy out vs energy in gives you around 300% with a heat pump. If the
OP will se significant use of the heating, this would be a far better
bet.

IRL though, total energy out / total energy in isnt the relevant figure
of merit. What is more to the point is energy out when its wanted /
energy in, and in this respect oil filled rads are the worst
performers. They will also take longer to heat the room with the same
power rating. Both because of thermal storage.
