Hi, today i heard air in the heating system so i thought i would bleed the radiators to get rid of it, thinking i was doing the right thing. However what i didn't know was that the system was low on water. Even though water comes out of the radiators i now get the F22 error code on the boiler. I know this means refil it. HOWEVER, the question is how!? It's all quite urgent as it's come at a bad time because of things that are happening in the flat. I've been told it's pretty straight forward, but just don't know what part is for the cold water inlet.
Can anyone help???
