Hi
I have a Potterton Gold 24he combi that keeps losing pressure, needing refilled every 24 hrs. Error code points to an issue with the fan, but i think there has to be another fault to account for the lost pressure?
When the flow and return pipes are switched off at the boiler, and left to stand for 5 hours, the pressure dropped from 2.0 to 1.8bar. However, when switched back on (to HW function only, with CH pipes still off) it dropped another 0.5bar immediately. Pretty sure there isn't a leak in the pipework as spoken to downstairs neighbours; rads also checked for leaks.
I've not been able to check the pressure relief pipe as it rises vertically for about 8ft and exits on to the roof of the building (a 4 storey block of flats). I'm aware this is against regs and looking to reroute the pipework.
CH engineer said i need to replace the fan (£150 + labour). However, before i go ahead with this, just want to check what others think might be causing the loss of pressure.
thanks
