Cold Radiator

[jacew]

I have a radiator which never worked since i bought the house. I got a plumber in and they changed the thermostatic valve and it still didn't work but after a few days as if by magic it started working. I suspected an airlock maybe.

Well I've had to drain the system to replace a different radiator elsewhere in the house and now the radiator doesn't work again. I've given it a few days and still no joy.

I've tried turning off several radiators in the thope the pump can push out the airlock, but to no avail.

Anybody have any other ideas i can try.

TIA

i assume from the air lock its a gravity c/h. does the rad in question have a drain off valve ? if so u could attach a hose and open it and alow some water to rush out hopefully moving ur air lock
