Id think its unlikely from what you say that itd be hydrogen build up, test some of the air from the rad to see if is hydrogen bt a dnt think it wuld be. and yes air can be drawn in through little cracks in the joints that otherwise you wont notice leaking, dunno if theyd let that much air...

Hi all. I'm just asking this out of curiosity to explain to customers and for my own information. I'm a gas man and on a call out last week i found the boiler was fine and it was the power supply to the boiler, and the kitchen sockets had reverse polarity. I was just wandering what...
