Hi, I have recently used a chemical flush on my heating so drained down the gravity fed system. After the flush have refilled and bled rads, but when I turn it on the boiler starts and runs for abt 10 mins then stops? I’m wondering if I have air locks somewhere?

Small tank in loft is feed and expansion tank ( cistern) does not indicate a gravity system
Present on gravity or pumped open systems
At worst you have gravity primary circulation to the hot water cylinder
But the heating is pumped / forced circulation
Unlikely to be a full gravity system ????

Drain down and fill up what could go wrong. Hmmm.
