Like me it's knocking on a bit. This same pump has worked flawlessly for 31 years so it is time for a new one.
I would just like to say

Yes, the boiler is running at a reduced temp, but the pump is now so slow and "knocking" it isn't getting the flow to pull the heat out of the boiler fast enough.
I will see if I can put the new pump on tomorrow. It will get us through tonight (10:30 stop) and tomorrow morning (07:30 start).
I fink they is all A rated pumps these days, they don't gots a switch any more.
The Grundfos ones we flog has different settings for constant flow, constant delta p an wot not dependin on duty.

This pic from "the Birds" which many peeps find more scary for some weird reason than chainsaw massacre etc etc.

Is the pressure differential across the system, delta bein the lazy way to say D, like in maffs
The flow required to rads varies coz they has their own therm controlled valves (these days) whereas unner floor heating wants constant flow to maintain the delta t.. Consistent temperature drop across the zones as they usually have a designated tee em vee. Least that what the nipper at work says

I don't go for either the ridiculous Hammer Horror stuff or the "chop em up, blow em up, shed loads of blood" sh!t.
but Hitch is much more fun, some of it is actually quite a laugh. always clever, always got an interesting plot, and very little or no blood. much more psychological thrillers. Give em a go. i bet you'll like em!

D in Maffs? no idea! (I got an E in Maffs A level!)
We only has one controlled valve and it is always open to the max. I simply turn the valves off in the rooms we don't use.
Dottir and her bloke are doing their old thatched place up, concreting the floors and installing under-floor heating. I'll have to ask them if their pump will maintain the TMV and see what they say!
