Hi all,
I would like some advise on installing an external CH expansion vessel.
Some background to begin. I have a Vokera combination boiler and it is loosing system pressure when the heating is on, as the pressure gauge reaches 3 bar and the pressure safety valve opens. I have checked the expansion vessel behind the boiler and water comes out of the valve on top of the expansion vessel. To me this indicates that the internal "balloon" has ruptured.
I understand that the simplest and cheapest method would be to install an external expansion vessel on the return pipe as close as possible to the boiler . I can install one next to the mains water filling loop. Is it a good idea to replace the filling loop with a loop that has a t-piece connection so as to allow the expansion vessel pipework be connected to the system? or would it be best to cut into the return pipe and put in a compression fitting t-piece? As the boiler has a safety valve do I need one on the external expansion vessel as well?
