Thanks to the test done on the advice from ChrisR :D , (and from Worcester-Bosch engineer no.3), today's engineer (no. 4) went straight to the Heat Exchanger and agreed the fault is there. A new fan is also required, incedently - it packed up on Monday. Only trouble was, they don't carry...

1 Start with boiler cold - ok 2 Set boiler pressure to 2 bar - did this at 11:am 3 Close boiler isolation valves - also did this at 11:am don't use CH OR HW 4 Leave as long as possible - a few hours might well be enough. 5 Read pressure gauge - at 3:30pm the pressure had dropped to...

The rate of pressure loss before the engineers came, was about 1 bar every 2 days (like last year). Only since the engineers has the pressure loss been 1 bar every 2 hours. This is why we suspect the boiler despite all advice to the contrary. Thanks

We have a Worcester-Bosch Greenstar Combi boiler that is 4 years old, including the central heating system. A year ago we noticed that the pressure in the system would drop by about 1 bar every couple of days. During the warmer months, when the heating was off, the pressure loss was minimal...
