24 ri condensing boiler sorry

I'm sure he did, but if the system has been partly/fully drained then I'm assuming he vented the heat exchanger in side the boiler after refilling? If so then the next thing I'd do is turn off any rads that are heating to see if the others push through any air. Failing that it's check/replace the pump.

Thanks mate!

Ok so the pump is making all the right noises and these noises change when I move the white thing from 1 to 2 to 3.

Currently got it on 2.

The pump is red hot to touch and one of the pipes going in is too. My radiators though are still cold

How do I know if the pump isn’t working properly when it sounds like it is?

Thanks as ever

 

[Hibster]

What's the pipe coming like (temperature wise)? Is the heat passing through the heating side of the 3 port valve

 

[Oakwood109]

Too hot to touch! Only got the central heating valve on at the moment, water is off

 

[Oakwood109]

Rad closest boiler is red hot, next one along is hot at fill tap but barely warm elsewhere. Rest are cold

 

[Hibster]

I would say get the pump looked at/changed. If the impeller has sheared then you'll only be hearing the motor sound changing when moving the selector.

Thanks mate!

Ok first off can I say thanks very much to everyone for taking the time to help. Turns out the pump was bust and I now have a brand new grundfos churning out heat from these rads like I’ve never had!

Trouble is the sparky has left me in a bit of a pickle. The heating now won’t turn off! The controller is off at the wall but heating still blazing out and I also can’t get any hot water

The saga continues

Obviously I will be calling the sparky back butnin the meantime is there any way I can get the heating off and the water on?!

Thanks
