Radiator only getting hot on bottom half?

Forget previous answer, the filling loop as it's called will either be near the boiler or sometimes in the airing cupboard,it is usually close to a pressure gauge so top up to 1-1.5 bar then vent the radiator after filling radiator re-check pressure

you need to back fill up that rad,, you need to get the pressure gage up bar 1.0, at the boiler, there should be a tap under your sink to turn up so you can refill that rad up to the top with water, if you find it, get some to keep a eye on the gage, and you turn the tap very slow , and when the arrow hits 1.0 bar, turn the tap off, and that rad will be hot all the way up. ps sorry about the spelling,
