It is probably cutting out on the thermostat as it reaches temperature, then it just pumps that water round the heating until it cools then it fires up again. Your hot water never cools as it is being used so the boiler will be firing constanyly.
it used too do that.now the pilot light goes out ,i have to re-ignite it
the boiler fires up for about 5 mins.rads get hot.then pilot light goes out.it seems that when the boiler needs to fire up again,thats when the p/light goes out.normally the p/light is always on.

what do you mean by that,DP????
Your post suggests that the pilot only goes out when the boiler is running. It does not say the pilot goes out when the boiler is not in use. Thermocouple would not be selective- pilot would go out when boiler is idle as well as when a demand is in place if it were defective.
What if the boiler is putting the pilot out because of a fault condition. It can do that.
