I’m no expert but I don’t think you pressurise that vessel with water. Looks like your heating system needs topping up. Open both valves on that flexible hose.

edit: As lightning says above.
 
Open the two back handles till 1.5 bar then close them


"black" handles

They are open when the lever is in line with the pipe.

There are two so that when you have adjusted the pressure, you shut them both, because it is important that there must be no leakage at other times, even if one valve might become worn or fail.

Leakage could allow water from the heating system to contaminate the fresh water supply to the house.

To ensure this cannot happen the flexible hose should be disconnected after the system has been re-pressurised

Hence the flexible hose connections are designed with wing nuts that enable them to be undone by hand without the use of a tool
 
Do you have a link for that as it sounds like complete rubbish ?

It was the student house my daughter spent a year in. The lack of flexible was just one of several items that the letting agent took up with the landlord following an inspection of the property. If I recall correctly other houses owned and "maintained" by the landlord were inspected and some were taken off the student accommodation register
 
Many boiler manufacturers (including Vaillant) design there boilers such that the integral filling loops are difficult to remove after topping up by the user...they manage to get their boilers through approvals showing the abuse of the regulations.
I suspect the letting agent quite rightly didn't want the students messing about topping up pressure (which invariably they screw up causing damage).
 
Oh, you're such a wag, Bernard.

Boring and irritating - but so, so amusing.
 
It is not a student accommodation. It was done before by a plumber, but due to the pandemic we have to do it by ourselves now.
