Moved into a property recently and have a problem with one radiator which stays stone cold top and bottom.
This radiator is the only one without a trv valve. I have tried bleeding the radiator, also shutting down all other radiators and leaving this one on but that didn't work.
Today I removed the radiator and flushed it through with a hose, not much sludge if any came out, just some brown water.
Whilst the radiator was removed I opened both valves to check they opened OK which they did. I then reattached the radiator and opened the valve, it refilled fine with water, but when restarting the boiler it is still stone cold. The pipe up to the valve gets hot though, a ideas please?
