Hello everyone.
I'm currently having issues my boiler. We bought our house recently and the boiler in the home was just two years old. It's a Vaillant Combi boiler which services about 13 rads over three floors.
When we moved in we had no issues with the heating at all. We had a new cooker installed and due to the gas being turned off we had a F fault on the boiler. I didn't noticed this until the next day so I reset the boiler and them I had a low pressure F fault. I opened the cold in valve to re pressurise and put it to just over 1.0 bar.
This solved it until we had a spell of cold weather and the system was losing pressure daily. I checked for leaks and found none whatsoever. No is colder still, I wake I the morning to find the pressure at 0.0 bar. When I fill it to 1.0 bar, the CH will kick in, in the evening, but the pressure goes to 3.0 bar, which then makes the PRV to kick in and the copper pipe on the outside drips. So much so, that when the CH turns off, the pressure goes to 0.0 bar when we wake up.
I'm not certain what the issue is and I haven't checked the Air pressure as I not sure if this is the issue.
Any help would be great as I'd like to save money if its something I can do myself rather than call out an engineer. Which I fear will be inevitable.
