I saw that Mira were doing an eco shower head that claims to use a
venturi to aerate the water so that it feels like a "normal" shower
head but uses much less water, reducing water costs and heating costs.

I was thinking of giving it a go, but I searches the internet and
found someone saying this: "I don't think theres any replacement for
volume and pressure of water personally. Aerating heads give the
impression of more water but aren't very effective at actually getting
rid of the soap (and cool the water - which you compensate for by
turning up the temperature)."

Yeah, we've had one for a few years. As the parent of three then-teenagers
I was getting ****ed off with them ignoring all requests to reduce their
shower duration to less than about 30 minutes, and consequently continually
draining the hot tank. I fitted a Mira eco jobbie in the family bathroom
(we have a mains pressure hot water system which generates really good
showers).

It's definitely made a big difference to the overall hot water consumption.
I wouldn't say it's quite as nice to shower under as a standard shower head
(which I've retained in our en-suite) but it's really pretty good, and I
certainly don't have a problem using it on occasions when I use the family
bathroom. I would say they are "not quite as effective at getting rid of
soap" (or mor accurately "not quite as quick") rather than "aren't very
effective", but they are still perfectly OK. Hadn't noticed any water
cooling effect; hadn't occurred to me, but if it happens (which sounds
plausible) it must be pretty minimal; and as I say, we use far less hot
water since I fitted the thing.

One other point is that it's actually quite noisy in use compared to a
conventional shower head. Doesn't bother me, but it irritates SWMBO. I
think you'd only really notice it if you regularly use a standard shower in
parallel (ie as we do).
