Hello all,
The pressure gauge on the above keeps creeping up - I just checked, and it was nearing 2.5 bar (at which point, the book says call an engineer). I then had a shower and checked again - it was down to 2 bar.
I would have thought that the pressure would only reduce with time, given that no new water is being introduced into the system, and that there must inevitably be some leak (however tiny) somewhere.
What are the possible causes? And the possible consequences?
We haven't had any work done in yonks, and live in a hard water area. We leave the heating on low but constant, and have about four showers a day.
I don't think that the filling loop tap is letting any water through.
On a related thing, is there an optimum pressure that a system should run at (for economy, for the sake of argument)?
