All,
Need some ideas pleaeses and thanks.
Customer had drained system and had awful air locks, went round boiled out and got working... GREAT!
2 weeks later after some bumping and banging, no hot water. Went round and flow red hot, nothing on the return.
Boiled again... Got hot water... Worked perfectly for around 2 weeks and then same pattern.
The header tank is in a super awkward position (in a small cupboard with the roof straight above behind the larger dhw tank). I noticed that the vent pipe was in the water, so I cut and lifted. I have also popped a thumb vent on the return. Boiled again, got running and this time after 11 days and some more noise there is once again no hot water.
The gravity valve is somewhat (somewhat being a debatable word) accessible, I'm going to swap this out... But really bloody scratching my head!
THOUGHTS WELCOME!
