Worcester boiler shutdown after a few hours

[superdupergasman]

Get a thermometer on the flow away from the heat exchanger to see what the water temp is getting up to.

If its getting up past the 80oC then could be the boiler stat/ thermistor letting it run to long hence tripping the overheat at 100oC

Also could be a slugish pump not getting the water away from the boiler fast enough or some sludge in the boiler.

Hi Superdupergasman

That's why I am confused - the overheat ISN'T tripping at all - and the boiler can be relit without touching the overheat ....

Thanks for your input tho.
