Hi everyone,
I guess like most other newbies here I need help/advice, so here goes.
Boiler is about 8 years old & been a bit of hassle for last 12 months. I recently fitted a new PRV to this & suspected from reading up on the matter there maybe another underlying problem & this has proved to be the case.
Visible or audible problem - Rapidly heats upto U9 & pressure gauge jumps from 1 to 3 bar, i suspect from there it dumps through the PRV. The pressure gauge fluctuation is also accompanied with pipe banging sounds within the boiler, this last only a few seconds & then the boiler does start to cool.
Resetting the boiler appears to open a valve or something as the temperature drops as fast as it went up (on most occassions)
The above problem almost always happens when hot water is demanded, the heating does work but I guess the boiler is going the this heating & cooling process so some heat is achieved from the radiators.
From my understanding through reading up the problems could be one or more of the following, pump, expansions vessel, diverter valve prv, heat exchanger, pcb or in otherwords a new boiler.
The diverter valve does appear to have a problem as when the boiler is in cool state it does not always provide hot water, switching tap on & off eventually gives hot water.
Hopefully I have provided enough info for someone to provide tips to help resolve. Thanks in advance
