is there any quick and easy way of stoping it thanks

Isn't that boiler supposed to have a pump overrun stat or something? I vaguely remember installing one back around 1980. Sounds like the pump is stopping too quickly as namsag said. I don't suppose anyone's got any MIs for it?

Na they never had a pump over run on them chris even though they where low water content copper.

Doubt you will get a stat for it as these date back to early to mid 70`s where renamed glowworm feulsaver when gloworm bought out radiation

Out of interest chris does it give you a production year in manual

Choice of boiler stat gone and it is getting too hot or boiler is full of scale and it is not getting rid of it`s heat so is noisy,
My thought on this particular boiler is if the heat exchanger was badly scaled it would be noisy all the time not just as it turns off.

No, but it was in the days of Radiation - Ascot when they were part of TI (Tube Investments).
