I guess the only way is to get the unvented, run the new 22mm copper to it and see what it spits out? Then look at accumulators and the like if I'm not happy??

Pretty much, yes. 22mm copper should help a bit but an accumulator will have the greatest effect on your flow rate given that you've got fairly decent static pressure. Doing both would be the best option, of course

Max flow rate from one of those is 12l/min, so they won't help. You seem out of your depth here, maybe go advise people on how to change tap washers or something you actually understand?

Phil asked if there were any other options. I don't know how much Phil is looking to spend but unvented cylinders and accumulators will run into thousands. Just trying to offer another option. Of course an unvented is the most favourable option imho. Phil's primary concern is getting a good flow rate through his shower head. A larger cylinder and a pump would achieve this. Obviously recovery time, noise etc are concerns with this set-up.

Read what I actually wrote. It was a question. I wasn't suggesting it would work. Grab some cocoa and breathe dadio. I've never used one and I don't particularly like the idea. I asked if anyone else had. I didn't know what flow rate they provide as I've never been sufficiently interested or had reason to find out. You're first sentence was sufficient.
It's the last I'll say on the matter before Muggles tells me off again. Boiler has 34KW DHW output max and 30KW heating output max at factory settings. Max heating output can be matched to system requirement (let's say, for example 50% = 15KW). Boiler can still modulate down but not past the new set limit. Anyway, willy waving isn't going to help Phil.
