Radiator Heating Fault
Hi
I have a gas combi boiler and one of the radiators is heating at the top, is lukewarm at the bottom with the pipe below the lockshield valve also lukewarm.
Does anyone have any suggestions as to the potential cause?
Kind Regards

"Hello this sounds like a flow issue , could be a pump issue or a blockage in the radiator
When you have air in the system the top of the radiator will go luke warm but when the bottom of the radiator goes luke warm its a flow issue
I hope this helps and we are always happy to take a closer look"

"Hi Brad
Most likely cause of this is an airlock in pipework, or system may require balancing"

"Cause of problem is just breakdown of the radiator, water reacting with the ferrous(steel in radiator)causes sluge. Best solution would be to close both valves and take radiator off and clean it out the correct way would be to have your system power flushed also would make sure that the magnetic filter is clean preferably done by an engineer during service and then inhibitor to be put in to help prevent the erosion process."
