    The copper vent pipe above and to the side should go in to the cistern.

    Presumerably it's redundant...your heating/hot water wouldn't last too long with no water in there.
    Post pics of the boiler/hot water cylinder to confirm.

    Cistern looks half full to me especially in the first pic. Could easily be wrong though.

    Indeed, teach me to look at the pic on the phone :)
    Float arm looks horizontal with a nice biofilm on the water, bit of timber needed to support the safety vent pipe over the cistern.

    It's about half full, the water around 12-15 cm in depth.

    My hot water wasn't on at the time I took the pics, but the hot water works fine when I do switch it on; the boiler in the kitchen kicking into action.

    I don't use my central heating system - EVER!

    The hot water cylinder (tank?) is just a massive cylinder in a cupboard off the top hallway - it is not transparent.

    I do not understand the above, please explain in further detail.

    Is this just an observation or points that require action?

    Please explain this in more detail.

    Thanks.

    The pipe in red should be above the cistern so any water coming out of it will go into the cistern.

    Thanks for noticing that, I've now adjusted, the pipe now leads into the small tank (cistern?)

    It's the 'Feed and expansion' cistern, (in Plumbing terms a 'tank' is a sealed vessel, whereas a 'cistern' has a removeable lid and operates at atmospheric pressure.) Supplies your hot water/central heating system with water as required, (under normal operation system should remain full and circulate the same water unless there's a leak anywhere).

    Ideally needs a lid fitting, and some insulation over the top to provide frost protection.

    Looks to me that the ( large white) overflow pipe is higher - @ it's bottom edge - than the float valve at the opposite end of the cistern . That is incorrect as the water with it's biofilm could be sucked back into the mains water supply . Measurement from the top edge of the cistern needed. _could be an optical illusion.

    Maybe the lid is around somewhere as it could have been removed to add chemical to the system.... there's a plastic container to the left which could have held them?

    I checked, the bottom (underside) of the overflow pipe is 1.3 cm lower than the water inlet. Both distances were measured from the bottom of the cistern tank.


    Yeah it was, I found it.


    I extracted the muggy water first of all by using a container:

    Then I had to use a handpump for the rest:

    It wasn't nice the colour of the toilet water:

    This is what was left:

    I appear to have had some residents;

    20200802_092105.jpg


    Gave it a good clean:

    20200802_093650.jpg


    Then open the water inlet valve:

    20200802_093902.jpg


    Nearly there:

    Finally, the insulated cover:

    Job done!
