Clearly too good for you the forum bully, 5'1" in your high heels

I never said you or your shoes were ordinary.
No ! In a pumped system gravity has no relevanve.
The whole point of balancing is to set a similar flow rate into each rad, having some regard for its heat output.
That enables all the rads to heat up quickly and for the temperature differential to be similar so that the system responds correctly.
Unfortunately, many people in the plumbing business dont understand some of the more basic facts and are unable to think them out for themselves. Thats why some forums will give you incorrect information.
You have now seen the benefit of the advice I gave you and I hope that some others will take note, particularly as I take to trouble to explain why!
A few weeks ago I needed to advise this lady to have a gate valve fitted to her cylinder to solve a problem. Her plumber could not understand why it was needed so he called me and I explained it to him. He was surprised but accepted my explanation, fitted it and learnt from that experience when he saw that it did the trick.

Thanks for explaining
I think that the 6 metre difference in pressure top rad to bottom rad plays some part in deciding first where the hot water from the boiler goes when it first fires up
as hot water likes to rise up a pipe again I think its going to go upstairs sooner than downhill - however insignifican to some this may be
I wonder if it was the same expert installer here that also fitted the bath to the wall using a tube of silicone and size 12 screws directly into plasterboard (not even using rawlplugs). Perhaps he also used old plastic pipe brackets as the cistern washers and didnt think it wise to fit a stop end on a unused washing machine valve and fitted plastic right up to the basin flexi`s ?

In a pumped system, convection is negligible.
It's insignificant.
Have you come here just to have a go at your installer?
But does it leak, or wobble, or have any other problem with it?
You can think whatever you like but with a pump circulating the water it is not the case!
The pump has a head of up to 5 metres.
Thermal convection can have an absolute maximum theoretical effect of 0.24 metres, in practice less than 0.1 metres! That will be totally swamped by the pump head.

Mine looks wobbly, but if anyone tries to grab it they find it surprisingly rigid.
