Thanks for that desktop. Yes a circulation issue does seem to be the consensus and will investigate with my plumber. The only thing is, I thought the boiler temperature would need to be much higher say 80 or so for it to short cycle. Can I be sure the boiler is working ok?

Is the system sealed or open vent?
If the flow is only reaching 64degC on max then it's not an overheat causing it to cycle, if that was the case then it wouldn't normally run for ages, usually an overheat occurs relatively quickly on a boiler that can't get rid of it's heat. With this one it seems the boiler is reaching set temp and that's when it short cycles.
How is the new pump set up?
