BOILER STOPS WORKING

[aks_72]

Can some one help
I have a Glowworm 85/10 floor standing boiler linked to a gravity fed hot water and a pumped heating system.
The problem I have is that the boiler pilot keeps going out, I lite it, turn the heating on. Then say between 10 to about a few hours the rads will cool down, I check the boiler, Its stopped and upon checking the pilot it gone out.
I though that once the boiler was one the pilot would remain one because of the heat within, so why does it go off.
I have changed the temo-couple yesterday, but that hasn't helped.
could air or a lack of circulation in the pump be causing this.

P.S I do not have a problem with igniting my pilot it ignites fine and stays on it only when the boiler kicks it i believe the problem occurs.

Please help it freeeezing...

There are many reasons why a pilot light can still go out with a new thermocouple.

Gas supply problems, gas valve, pilot light itself and on some models an overheat stat !

All these should be investigated by a competent boiler engineer who would normally be CORGI registered.

Would a service solve this?
