I watched my CH slowly degrade over the past months until I finally blocked it up completely with all my draining and flushing. Thanks to tips on this site I finally got some normality back - but it's not perfect.
It's a vented system. Did have a Myson Unit 3 pump which I replaced with a seemingly unused Grundfos 15/50 that has been in a box since we moved in 15years ago. It didn't solve the problems (but a weekend of flushing and additional venting did make a huge improvment).
I'm not convinced it's back to normal though and maybe the pump is not good enough (due age, storage and the fact I accidently ran it dry for 15-30 minutes) so will replace it with a Wilo Smart Pump. Note the pumping is into the system (i.e downwards) with an Aerjec just above.
My question is. If I still feel that there is not enough "oomph" in the system will fitting two pumps improve the flow? I was thinking of putting the spare one in the feed between the boiler output and the aerjec input.
I have flushed out enough gunge to halve OPEC oil prices so reckon the system is clean.
