I don't get enough heat out of the radiator

In my case, the needed power to heat the room is 1400 W and I have selected a radiator to deliver this. However, in the Heating design simulation with this radiator, the actual radiator power is only 900 W and this is not enough to heat the room.

The size of the radiator is given with respect to some (editable) rated temperature conditions (see image below) and it will deliver the needed heat only if the actual supply water temperature is high enough. First, check the supply temperature curve to the radiator. This is given under Heat on the Building tab. If the supply temperature setpoint is high enough, make sure that your Topup heating unit is able to deliver sufficient power.
