The other option may be to put a black over the expansion pipe, connect the gravity fed cold to the hot and then the cold water mains to the hot making sure all taps are running for at least a minute.

My shower has a hot or cold water airlock, how can this be fixed
When a shower or any other similar set up gets an airlock, this is normally due to the pipework going up into the attic and then feeding down with no vent.

I have water coming out in all taps except for one tap, what can this be
If you have water coming out of all the taps apart from one then the airlock may be more local that you think.
