Hello - I have an f.22 error on this system boiler, 0.4 bars. Just moved into this house so not certain on how everything works. There are no taps under the boiler to add more water.
There is a hot water cylinder in the cellar so thankfully it's just heating that we have lost.
With this boiler would there be filling loop somewhere else that I just haven't found, or do I need to adjust something under the boiler with a screwdriver?
