Vent with condensate

This vent runs loud and releases condensation. That room (a bathroom) also gets hotter than others. I’ve tried replacing it and have also drained & skimmed the boiler (which has helped other issues but not this)

The bathroom with that radiator was recently renovated so it was removed and reattached. We also had our attic finished which added another heating zone onto the same boiler. I’ve seen the issue in the bathroom with & without the attic heat running

any ideas?

No problem before renovation?

No problem before

The flooring changed so the height is a bit different. I fixed the pitch after the renovation to see if that would help. The pitch looks right now (a level shows it tilts back towards the supply) and did reduce the amount of water coming out (it was shooting out at first) but I still have this issue

Is your pressure gauge on the boiler reading pressure? If so how much?

Any issue in other parts of the house?

pressure is set at 10 kPa. Another vent was loud in a different part of the house but has been fine since I replaced it

Pressure is OK… have you tried a different (slower) vent?

i switched the vent to a slower one and have had it running for a handful of cycles. the noise & condensation issues seem to be gone. the radiator still seems to run much hotter than others upstairs, but sometimes you can't have it all! thanks for the help
