We've got an outbuilding that has a radiator in it spurred of our house central heating. It was working ok but is now stone cold. The radiator was installed when the previous owners converted the detached garage into a home office about three years ago.
It has been built into a cabinet so without ripping that apart I can only just reach the TRV the lockshield and the bleed screw.
This is what I've tried. I closed the TRV and lockshield and opened the bleedscrew fully. Then I opened the TRV and the water squirted out into the bucket I'd put ready. I left it like this for a few minutes until I could feel the valve body getting warm so I know water is getting there from the boiler. Then I closed the TRV and opened the lockshield. The water still squirts out of the bleedscrew but apparently not quite under the same pressure judging by the arc of the stream.
So I know the pipes between the house and the outhouse aren't blocked. Any ideas how I can fix it?
