Do you have a combi boiler or do you have a hot water cylinder in an airing cupboard?
If you have a combi boiler you will need to keep topping up the water level in the system. If you have a hot water cylinder you have a conventional system that will top itself up.
Not sure why people are saying do it with the system hot? I can not see a reason why you can't bleed them without the system fully hot. Cold air will come out of the bleed valve.
