I drained my CH system yesterday and fitted a new radiator and towel warmer, where previously there had been one radiator.
I switched the combi-boiler back on using the timer but noticed the pilot had gone out. I relit it okay, but when the boiler fires up fully there is a very loud banging and it shuts down again. This happens for both the HW and the CH. I let it run for a couple of hours and the new radiator heated up but none of the others, plus there is no HW. All radiators have been bled.
I thought it might settle down overnight but was rudely awakened at 4.30 when the timer kicked in and there was this almighty banging. Had to have a luke warm shower this morning and a grumpy missus through my incompetence.
Any ideas to help please?
