Any help will be greatly appreciated because this radiator is driving me crazy.
setup
======
Open vented system
Microbore
Oil burner
11 radiators
Problem
======
Small first floor radiator stop heating up. Being quite old I suspected that possibly was blocked so I replaced it with a new one. I took the opportunity to replace 3 ground floor radiators at the same time.
Result, top radiator still not heating up (but its a new one now) the other are fine.
I noticed that the pipe heats up to the TVR valve but not the radiator.
Bleeding the radiator has no effect - in fact the water just drips out of the bleeding valve with no pressure.
NB.
TVR and lockshield valves are brand new.
Drained and refill system 3 times
Any ideas anybody ?
Thanks in anticipation
