IMO you have an airlock, some rads will heat, but because of the air in the system the heated water can only go so far because of the air lock. Or maybe there is no water in the header supply tank.

Header tank is full, each radiator has water at it so surely any airlock would have stopped any water getting there ay all?
Are the diverter valves controlled by electricity?

Yes, they are wired to some sort of distribution box in the crawl space behind the tank.

Call a plumber. Don't mess with things you know nowt about. It can turn out very costly.

Turn the valves off at the rads that are working, turn the heating on, when one of the cold rads heats up then turn its valves off move to next rad that heats up and so on .This should force the air to the last rad then bleed it. Open all the valves , then you'll have to adjust each rad to balance the system,

No not me I'm just passing on info from my mate, a proper plumber :smirk:
Is it possible that when you drained the system you left the supply to the diverter valves on?
If they run with no water there's a risk of the motor burning out and the valve sticking in a closed position, hence no water to certain areas.

If the issue is not hot enough, have you considered adding a few jalapenos?

Is it fixed yet , and what was the problem ??.

Turn all the rads off, turn one that doesn't work on and it should heat as it will force the flow to that rad, continue the same process though each rad that doesn't work. Simple.

See post 27He's probably frozen to death by now. :mmm:
I havent frozen but the problem still exists. Even turning all the working ones off at the TRVs does nothing.
After about a days worth of chasing up and down stairs and in and out of the attic to no avail.

I think you may have to turn both rad valves off, but try what it says in post 33.

So just noticed that I also dont have hot water unless I manually open the zone valve. This just gets weirder.

Do you have a header tank for the heating ( with a ball valve) or a sealed pressurised tank?
If a sealed tank does it have any water in it? What's the pressure reading?

C'mon Greig,
It's hardly thermodynamics ... Is plumbing really that difficult?

It wasnt for the other 7 radiators I replaced last year. Hall eas the last one.
Now its tirned in to some sort of riddle.
As before Phil, header tank is full as normal. 6 of 9 radiators are working, albeit not at full capacity but at least working.
Each radiator is also full of water. Some just not getting hot waer and the hot water is now not right.
Cant believe this has come from a straight swap out.
