The displayed temperature is often taken from the cylinder top whereas the cylinder stat is installed ~ 1/4 the way up the cylinder, this is to start heating the water as soon as a relatively small volume is drawn off, say 30/50 litres. The coil is heating from the top down so your stat might call for heat at (63-5) 58C even though the cylinder top is slill at 63C and by the time the stat is satisfied again at 63C then the cylinder top wil be higher, in your case by 3C, 66C.I have chosen to set the CH temp to 63, but often find the water temp is displayed as high as 66, even when heat is staill being called for. Is this to be expected/normal?
I don’t think the issue is with the boiler on constantly (link could be correct for this problem), but with the boiler temp over shooting the set flow temp.If it’s relatively new, the link may have been left in.
Thanks, I was going off the curve ball ofI don’t think the issue is with the boiler on constantly (link could be correct for this problem), but with the boiler temp over shooting the set flow temp.
Could be, but it's a modulating boiler and CH is still calling for heat. It's as if it can't control the temp well.
So shouldn't stop the burner firing at SP temperature or it is and just going overtemp a little after burner shutdown?I don’t think the issue is with the boiler on constantly (link could be correct for this problem), but with the boiler temp over shooting the set flow temp.

The boiler shuts down when the stat no longer calls for heat. It occurs when the house is below the house/stat SP but the boiler water temp rises above the boiler's SP for water temp.I’m unsure.
We need more info really.
TBH, without other problems, I probably wouldn’t spend anytime fixing what is pretty much a non issue.
Yeah and it's all subjective, sadly. With many rads as hot as ever to the touch, it 'feels' like the boiler should be working hard, but perhaps not. Will keep an eye on it. Thanks all for the responses, appreciated.I mightn't, have worded that quite correctly but. If the rads heat demand is say 4kw and the boiler min output is 5 kw then the boiler temp will continue to rise until SP+5C , the burner will then cut out, the pump should continue to run the burner will then refire after the anti cycle time has elapsed and the cycle is repeated
