Boiler issues not firing after refill

[Notagainpike]

Leave it don’t reset if pump is running

Pump had stopped, started after reset. Did this twice, then had f11, did another reset, opened the drain on the heating return and seemed to get air out, or at least water that was very oxygenated....?
Left it 30 mins got heat at the one rad with no valves that i left on, bled this and had loads of air, gradually bringing one rad back on at a time and bleeding out...
Swems to be going in the right direction....

Pumps controlled via boiler so yes keep resetting if faulting out once one rad gets hot and you’ve bled it a few times and topped the pressure back up if dropped open another rad and leave the good one as is etc

Will take time but should shift

Is the general oppinion that the system has been plumbed up wrong, ie. It needs a bleed of, or is it just some do, some dont secnario....?

It’s good practice to put air vents in if the boiler is above the pipework eg drops down

Am i right in thinking the pump is sucking as is?

Yes once full of water will be fine

You can see from the diagram below anywhere the pipework goes upwards it should have an air vent (marked with an X). Radiators are massive catchments for air with an air vent. In theory

In the real world you can get over small high spots (such as floors being out of level), specially on a sealed system as its easier to clear. I'm one for never ever putting one in but I've seen tons of systems where some plumbers don't care

The second photo shows a system where no additional air vents are needed

Umh...it must of had its fair share of air by now....
So, should i be getting reg back to put a vent on to the pipe above the pump?

Ah right interesting....
So a need for a vent before i settle up....?

I wouldn't worry. Will only likely cause a problem once drained again and will take 2 mins to put a vent in there when you do

Someone has said, he wouldnt of plumbed it as its been done, i mean it works...but the poumt if this was to a, get better hot water pressure, and b, make the sytem moreb efficient....so i would like this to happen rather than have a system that isnt right
