I have a very confusing radiator problem!
I have a recently installed (1yr ago) combi boiler in a one-level flat, which appears to be working fine - it heats up 5 out of 7 of the radiators in my flat more than adequately. it doesnt heat 2 radiators though! (the bedrooms- great!)
the 2 radiators it doesnt heat, are the 2 furthest away. confusingly the pipe leading to one of them gets hot (but it takes a while) but the heat never gets past the lockshield valve. the radiator remains completely cold. ive bled it and re-bled it and its got no air locked. i also fully opened both valves- no heat. the lockshield valve appears to be on the flow side (ive guessed this because of the hot pipe - the TRV side is always cold).
so i closed both valves and drained the radiator down, then checked for a blockage at the lockshield side by opening it to see if it re-filled the radiator - it did. so no blockage that end i presumed...
i re-drained the radiator then ONLY opened the TRV which i thought was connected to the return pipe, but the radiator filled up through the TRV!!
what the heck is going on!? the radiator appears to being fed from both sides? is that possible? what might be faulty here? i'm baffled! please help -anyone!
