def a divertor fault for the heating of rads when running a hot water demand. Struggling to keep boiler fired can be a diaphragm on its way out, usual signs, downstairs fine, upstairs struggles to keep boiler fired, ive also seen these go after the water has been turned back on after work and the pressure is high and literally blown a hole through diaphragm. maybe a repair and service in order.
