You know the answer there are one thousand watts in a kilo watt.
The settings on the halogen heater are what you pay for.
The convector type wall heater is either on or off.
The on, being dependent on the existing room temperature, so you cannot say how much per hour they will cost to use. (Except when they are fully on.)
However, the halogen heater being in the middle of the room, and aimed directly at you will feel warmer, whereas, the wall heaters will loose some of their heat, heating up the wall behind them, and the circulating, convected air will warm the walls and ceilings before you notice any warming effect from them.
Instant heat is best and cheapest, convected can work if on long enough and that depends on the size of room and its insulation. It will need to be a small room to have any effect at this time, being so cold.
