As the title says really.
Wife noticed this morning that the boiler (Vaillant) sounded like a car ticking over.
After boiler went off and we left it for 10 minutes before firing it again it sounded more or less normal.
It was after calling for hot water (CH had gone off) - not sure if it's significant - and we have the pre-heat function switched on on the boiler. We had used both sjowers at the same time and the CH was also running at full whack - although this is usual in a morning.
Any advice much appreciated. I'd rather get a plumber out now than Christmas day
