Yet another (again!) boiler Q

[richfzs]

MrsRichfzs needs a new boiler, and the guy she's had round is recommending a direct replacement (non-combi) to use the existing header tanks & hot water tanks etc. I thought the drive was to always put combis in now? Is there any benefit to sticking with the storage tanks?

Any info gratefully received etc etc, so that I can once again appear like the font of all knowledge to her  :lol
