The simple mains fed shower works quite well if the dynamic pressure is 2.0bar or greater as its flow control valve will then maintain a reasonable florate, I have a 9.0kw Triton T80Z upstairs with 2.5bar dynamic pressure downstairs and only have to adjust the temperature control a few times as the mains temp changes seasonally. If the dynamic pressure is 1.5bar ish, then a CWSC fed T80SR with its own integral pump is the better choice by far.
Shower size, 6 kW really? Seems a good shower.

I have never investigated it in that detail, I simply fitted it, and checked watched the wattage variation on the IHD.
I measure 2bar, on the ground floor, the shower is in the bathroom, on the first floor.

Interesting. But unless desperately poor why would you?
I have a big unvented but my showers have 8l restrictors - because I have teenagers and so am desperately poor (especially as they seem to have figured out that the rainfall heads aren't restricted). They'll be removed when I win the lottery or get rid of the teenagers.
My saving grace is that I have these fitted to each shower - the cold feed into the shower is actually warm.
