I suspect that there are other factors in play, for example maybe
we want warmer showers in winter than summer because the bathroom
is colder. So, maybe the answer is to heat the bathroom more,

In winter I generally appreciate a more vigorous hotter shower, and
use about 4kW. In summer I'm not looking for hot and am comfortable
with 3kW. (Having used higher power showers many times I don't know
why so many people like them.)

Its very subjective.

Experience and expectations vary enormously. Some people like the
physical sensation of a force of water from the shower, others not so
much. It also depends allot on the type of shower head etc.

Personally I like quite a powerful (and fairly hot) shower, but don't
find the need for more than 8 or 9 LPM, or to have it actually flay skin
from the body!

I my last place I had a 35kW combi that would do one excellent shower at
a time, or two "ok" ones. To be fair, if you had not experienced the
excellent version, you would not have really noticed. However if you
were half way though a shower, and someone then got in the other shower,
then you were aware in the drop off in flow rate and it felt "not as
good".

I am just about to commission two extra showers here, so it will be
interesting to see how two run in parallel from the unvented cylinder.
