Hi folks, just changed a single rad for a double in the kitchen. Switched boiler off ( gravity fed) drained water from system. Took the old rad off and fitted the new one. Refilled the system bled downstairs rads first the the up stairs ones. Switched on the boiler, then the heating and it fires up (the green light comes on) there is a glugging noise in the boiler and it switches off, ( ie green light goes off) does the same when I put the hot water on. Any ideas ?
