A 2013 boiler then, so not that old. You have to go into the D menu to check the output, which is the top 2 buttons, adjust code to 17, then cycle through to D.000, might be auto or a figure.

That's what I do with my Ecotec plus 418. In summer when it's just heating up the hot water cylinder, I set it to 12Kw. I tried mine on auto and like the OP's, it took an absolute age to warm up. I'm sure someone on here told me those boilers don't like the auto setting.
Given Vaillants software history (they've screwed up many times) you want to override any auto setting...what appears to work well in their test labs may not work well in a UK home.
It is normally always beneficial to range rate a boilers output regardless of the manufacturers recommendation or default settings.
