Adding inhibitor to radiator

Hi, i have this rad in bathroom. I have a sealed system.

I am going to be putting another one in bedroom back on wall after decorating room. Putting the old one back in bedroom & opening valves to refill it, would enough water drain out of one bathroom to be able to add inhibitor to it.

If not best way to add it.

The one in bathroom is the highest in the house. The pipework i have have is 10mm. Many thanks
