Already got one shower a long way from the tanks with a mira mode digital shower. Its the dogs nuts.
I'm starting to talk myself into getting another one for the bathroom next door to the cylinder and almost underneath the cold tank. Reason is I think while £500 is a lot of money, most of that will go back on the house and we're not sure what we're doing - we might well stay and it comes with a "bath filler" which looks very good especially for families with young kids or forgetful parents....
Anyway, my questions are:
1/ Planning on putting the mixer/pump into the loft above the bath/shower. I'm assuming I can tee off the existing dedicated 22mm feeds for the other mira shower which is also in the loft because its unlikely both showers would be run together and if it becomes a problem I could plumb it direct from the tanks after installation. I guess if they did run together they'd get starved of water and drastically reduce flow but is that the only issue?
2/ The bath outlet feed from the mira mixer/pump could come out in 15mm but it would be going down almost the full length of the room before reaching the bath. Could/should I upgrade that to run in mostly 22mm so the bath fills at least as quick as before or would it not make much difference?
Thanks a lot for reading and any constructive advice.

All runs should be in 22 then 15 if need be.
The bath taps would need 22 id say. Never seen then in 15 & there’s probably a good reason for that.
How big is the hwsc?
If you’re staying you want to do it right & do it once.

There's no taps - it comes out the overflow. hwsc - I don't know off hand how many litres but it is normal width size but about 6ft tall. I specced it years ago to quite a lot bigger than normal. I don't mind doing it twice haha - esp if first time might work ok. I've just never heard of two pumps.

In my opinion, 15 mm would be adequate because, a modern tap would ' bottle neck' any surplus water getting in the bath, Unless of course you get. 22mm full bore taps ( very expensive) and 22mm copper pipe right up to the tap, ( no flexi's), then it would show dividends,
