Turned off all at lockshield except the extension rad, put heating on and couldnt get it all hot. Soooo annoying

All are fully open, except the one i mentioned above.

So yesterday i put lockshield in off position on one of the rad upstairs. This morning turned heating on and opened that lockshield just a little bit and extension rad is fully hot ! Hopefully not some kind of weird one-off coincidence and it will stay that way !

Complicated stuff plumbing is ... Ill keep this post updates with my "balancing" ;)

Boiler installed new in 2021. So what result are we looking for ? If heating is ON, all rads (except column) fully hot and i start turning TRVs off one by one every 15mins. Lets say after 2 rads column heats up fully, what will that tell us ?

I switched them all off except the column one and thats when it heat up whole. Didnt do one by one. Ill try your suggestion on my day off as it seems like a longish process ;) So lets say i start opening one by one and then column starts cooling down after the third one. What does that mean and...

Thx. Will defo make sure he starts with balancing to solve the issue.

Got it. Thx for your wisdom everyone. Will see what builders will have to say and take it from there !

Wow. Id say a bit too much hassle for little reward. Id rather leave as it is and not mess with the boiler ...

Vaillant ecoTec plus 825. Installed in 2021.

So. All rads off, the extension one hot all over ! The good news is that i wont have to change it. Balancing issue ?

Got it. Thx a lot for your ideas. Ill post if there will be any new progress or what happened after turning all rads off !

The builders who built extension and done the rest not coming back until 2nd of jan. So trying to figure out meanwhile whats going on. So if i shut all TRV's on other rads and it still doesnt heat up whole, whats next ?

Might do that and if another one behaves the same then it is not rads fault ;)

After 3 rads off, bottom left was still luke warm although the area was smaller. Will switch off all rads and turn the heating on today. Will see what happens ..
