Conservatory radiator help

[pwmatt]

Hi All, would appreciate some advice on next steps with conservatory rad.

Single conservatory rad not heating up at all, neither pipe getting warm. All other rads in house working fine. So far I have checked the TRV which is not seized and also adjusted the lockshield which is also not seized. Rad backs onto another in the kitchen so was wondering if it was directly coming off that rad (conservatory built at time of house 20 yrs ago) however on turning off the kitchen rad didn't work. I have also turned off all the upstairs rads which again didn't help. During all my messing the pipe to the lockshield did start to warm up but only for 5 mins and then stopped without me doing anything else.

Can anyone suggest anything else to try before I get a professional in to look at it?

Thanks for the reply. Just to check, do you mean an air lock between the two rads? Which would be best to bleed first? I have tried to bleed to conservatory rad but there didn't seem to be any air. I will try this tomorrow though.

Best to remove the rad and put a hose pipe on each valve to outside and give it a flush out and then you can see if you get decent flow out of each side etc pipe could be blocked / kinked etc
