That's the thing with "radiators". They don't radiate much at all, it's air that comes into contact them that warms and rises, crosses the ceiling, then falls down the far wall as it cools. Then it travels across the floor to come into contact with the "radiator" again. It takes a while for the centre of the room to get warm.
In Germany, some homes have fans ABOVE the radiator, and they blow warmed air across the middle of the room. In the warmer months, they are used for cooling.
