I have to say, if this is important then wtf are you buying a Vaillant boiler!?
your plumber insists on fitting it?
they are trash, he'll be forever coming back replacing failed parts
£993 My plumber has been fitting them for years without a problem you just need to clean out the system properly I am also fitting a spirovent so hopefully it picks the crud up. Comes with 2 year warranty and I'll just have it serviced annually by Vaillant.
I would go for a Weissman boiler but they are a tad more expensive.
