Cool radiator - flow issue? Help please!

[Riley]

As stated pipework will not be able to supply enough energy/heat if teed into. Needs its own feed

Hi all - good news... problem solved!!

In frustration & desperation I went around the house checking all the trv valve pins moved freely, re-tried adjusting the manual bypass valve, gave the offending radiator and one feeding it plus pipework some firm taps to see if I could clear any debris, and adjusted the lockshield valve of the bad radiator plus one feeding it to balance flow between them... left system running for a while and came home to a hot house. It's the hottest it has ever been in the house and particularly downstairs. The bad rad and one feeding it are both hot too. Very pleased!! :54:

Would you recommend changing the manual bypass valve to an automatic one? I'm surprised it wasn't changed when the boiler and pump were replaced 2 years ago! (now that I know what one is!)

Thanks all

Yes would be better
