Ok I've turned off the heating flow and return valve. Bled the boiler and omg yes the valve is is blocked! I can't actually even see if there is a mesh type of filter or if it's a cartridge/cylinder type thing you pull out.
I've got a bottle of system descaler so I've got an old toothbrush and am dipping it in the cleaner and then cleaning up best I can on the part to see if I can break it down.

I do know we are in a hard water area and the reading is around 350ppm so we do get a fair bit of scale build up in general.

Right, I got to the cylinder in the valve and it was blocked definitely, I needed a screwdriver to push out the scale/gunk.
I feed up the boiler and the knocking has reduced but not stopped completely, it rises to above or around 80 degrees for a short time then goes back down to the 40 ish degrees. Couple of top rads are getting hot/warm but the down stairs are not. Some of the flow pipes downstairs get warm but not enough going around to circulate.

Hope that helps a bit more.

That seems to prove the circulation problem.

Perhaps there are blockages elsewhere on the system.

You could try adding some system cleaner such as Adey MC3+ and leaving it for a while to see if that helps

Ok I'll get some Adey mc3. I have a descaler but it's a qualrad one from Toolstation.

Would the Adey one be more to the job?

I put a Qualrad system cleaner in there a few days back when I drained the system down as well. Should I drain down to flush that out first before adding more in or another brand?

Adey was just an example, many others out there, but stick to a 'brand' name.

Yes, draining out would possibly help, getting loose stuff out first.

Unfortunately this seems to be a problem that will take local investigation to solve rather than a 'simple' answer from a forum.

Don't go spending any money on parts etc until you know the system is good and clean though.

Remember to check if there is a filter in the return isolation valve on the boiler.

Ok I'll get hold of a strong cleaner today like Fernox or Adey, drain down again and fill up with the cleaner in and give a good long run.

Many thanks, I will update on here.

Ok the return valve doesn't have the longer piece like the flow one had so no cylinder filter on there but perhaps there is a mesh type one inside the elbow?

When I drain it all down later I will take off the valve and check it's clear.

Cheers

Something like that seems up to the job or the Fernox800?

I mean the return valve fixed to the boiler under the right side as you look at the boiler.

There might be a mesh filter in there

Yes that's the one I cleared earlier today that was blocked with the mesh filter.

I've just drained out the system again and run a load of water through it all to give it a good clear out. The bought the Sentinel x800 and will add that now to 2/3 rads.

Added the x800 in last night. Ran it for a few hrs today. All rads getting hot and just sorting them out balancing the system etc.

I will run it some more later and again tomorrow before draining out and added an inhibitor.

Will post an update.

Thanks for all the help and suggestions gas4you.

I done a quick video of the boiler when I fired up this morning. The rads are working ok now again but for around 30 mins this is what it done and the temp stayed around 45 for the first 15 mins then goes up and the knocking gets very loud.

It's now running better and all rads hot.

So although I've cleaned the return valve and added in the cleaner could it still be that the pump is not quite up to scratch? Therefore the knocking noise on first fire up?
