Many thanks for all the suggestions.
I got myself a better pump and with this I set the Precharge Pressure to 2.1 bar as per the label.
Four days later I checked it again and it is holding aok.
Thanks again...!
Thanks for that.
On the label all it says is :-
Varem 24 litre
Precharge pressure 2.1 Bar
Max pressure 8 Bar
Working Temp -10 +100 degrees C
Date 07/96
The strange thing is everything seems to work ok.
Even the shower is good.
So I've no idea how long it has been like this...
Hi. I am very confused.
I have an unvented hot water storage system.
The system appears to be working ok.
In the airing cupboard there is a Tribune hot water cylinder with a Varem 24 litre vessel on the top of it.
I thought I should check the precharge pressure.
So I turned off the mains...
