Hot flow and return pipes, hot upstairs rad but cold rads downstairs

[ShaunCorbs]

Correct, not a single one

if it was just one or two i could see maybe a blockage but not all of them, i would say boiler is at fault

The pump could be spinning but not on full rate. Modern pumps are supposed to modulate dependant on demand.

I see, it still just seems strange how it cuts off at heating all radiators upstairs perfectly but none of the downstairs ones at all, they arent even luke warm. They are ice cold yet the return pipe to the boiler is super hot.

If your engineer cannot fix it, tell him you want him to book a warranty call from Vaillant.

I cannot say any more. Really sorry mate. Your engineer should know what to look at on the boiler.

Will do.

No worries I appreciate your help on this anyway, I'll update what it was once we've had it looked at.

Thanks again

That would be awesome mate. It’s always nice to get some feedback. It’s easy to forget us once it’s been fixed. UNTIL NEXT TIME

I am hoping that is the case, shelled out a lot of money for it and don't want to spend even more on additional work!

I would put money on it that it is diagnosed within 15 minutes

easy way to tell if its blocked but requires removal of a rad

remove a rad and test if you have water coming out of each valve from the rad you removed if you have its not blocked

Too right, will definitely update as I know how frustrating it is when you find a forum post with your problem and the OP never actually updates with what the solution was!
