beauty , that's my job tonight then.
correct me if im wrong
im going to plug the pump in so it is constant running open the 3 way valve to manual then go around bleeding the radiators checking the pump to see if the 27w rises , should I open one rad at a time or just go for it lol, I think @Brambles said start with all closed then open the nearest to the pump 1st then so on so on.
So if you do decide to give the "cold hydraulic route" a go I presume you will put the 3 way valve actuator to manual open which allows water flow to both CH&HW.
Might be an obvious one and you might not know either but has any plumber actually checked the pump valves are fully open?I did try it but won't go above 27w.
Tried with all rads shut bar 1 and that did do anything either.

That thought is in my mind as well, I would close each vale fully and then re open them, it should take ~ 4 full turns in either direction.Might be an obvious one and you might not know either but has any plumber actually checked the pump valves are fully open?
Well, it would seem that you have a full fledged blockage somewhere, what purpose does the red (gate) valve adjacent to the pump serve.?Just checked, both fully open and dropped to 26w now

Last suggestion is to shut pump isolation valves, remove pump, crack open pump discharge valve for a few minutes and get a back flow and ditto with pump suction valve, also pour some water through pump ports to prove clear, don't throw away your other pump either just in case the new one has been affected by any magnetite in the dirty water.
Progress update, plumbers have been today, 3.5 hours and looks like we are functional. It looks like it was air. They have simplified the pipework in the airing cupboard. Still sounds like a bit of air in the pipework though. Pump is running between 31 and 33w.
That's great news JP, that airing cupboard is well named. You should be circulating ~ 10/12 LPM if on speed 3.
Yeah is on speed 3 don't wanna mess with it lol
