New and wanting help. Air in the system?

[Ric2013]

Can you confirm that the cold to the shower is a separate pipe all the way to the cylinder?
Also, you say there is no flange to the cylinder. You do, however, have a separate pipe all the way from the shower to the cylinder for the hot? And how does this connect to the cylinder? Can you photo or sketch it for us?

Hot comes from the cylinder as seen on the photo. When in the loft, there is a cold feet that comes from the tank and runs parallel with the hot into the power shower.

They are mains as they got pressure. .

It is being fed by the tank and not mains. And hot water from cylinder.

Confused lol lol

I'm confused, wtf is that cold water feed doing attached to the HW outlet of of the cylinder? DIY job?

When I mentioned mains, I was talking about about the taps and not the shower.

The shower is hot fed from that pipe on the left that comes off that T thing. And cold from the tank in the loft.

What cold the two pipes on the left are hot out and the one on the right feeds the tank with cold water.

Ok I think I am getting somewhere.
As do only thing that changed was the Nest and having a schedule to come on 6-7am and 17-18pm.

So yesterday set the boiler to always on 24hr ...
And the power shower worked again and this morning still working.

I am confused ‍
Why the power shower only works when always It’s always on???
