Vertical radiator not heating up

[seweller51]

Hi all. Could someone help with a issue I have been having with my vertical radiator. I have one vertical radiator in my bungalow and it does not heat up unless the surrounding radiators are shut off. I have tried turning the surrounding radiators down but the have to be completely or very nearly off for the vertical one to heat, leaving the surrounding areas cold

Any suggestions on house to address this issue?

Many thanks
Paul

Have you tried balancing the other radiators?

Yes the rest of the radiators are working fine. Just the one vertical

I have a similar problem. Have fitted four verticals (1.6m x 0.5m) with two in one room on same run. Can only ever get one of the two hot and if I adjust them the hot one goes cold and the cold one hot!

Am thinking of increasing some of the pipework to 22mm with just 15mm spurs to the actual rads. Would this make any difference?

What’s the existing pipework ?

Hi, Sorry for delay but decided to draw a plan of layout. From Boiler it's 28mm running into 22mm down centre of property (all on one level). Then into 15mm for feeds to rads. Originally in lounge there was just one radiator behind hall wall. I replaced with two vertical rads the furthest of which is about 8m from 22/15mm transition. Its this run I am thinking of increasing to 22mm.

So the longe two don’t heat up what about the utility one on the same run ?

Only one of the two in the lounge heat up significantly (the other gets mildly warm). The utility one seems to heat up ok but this not a vertical radiator.

So both lounges eg back to back have issues ?

And the flow and return go into the correct port of the rad as it matters on
Verticals

To be clear, we only have one lounge and it has two vertical radiators. I seem unable to get both radiators to heat up sufficiently. If I close down very slightly the hot one, then it goes just warm and the other radiator which was previously warm gets hot. So never are both at the full level of heat.

Yes they are conected the right way. They had 'in' and 'out' stickers when purchased.
