I will be installing a new shower shortly and was wondering if any of
you had particular recommendations? Any pros and cons to look out for?

The water system provides hot and cold water at mains pressure
(modulating combi). Static water pressure is OK ( 3bar), flow rate up
to about 15l/min is available from the hot supply - although I would
like to use less than that so as to have something left for the rest of
the house.

I would go for a good quality thermostatic valve like a Mira, Grohe or
Aqualisa.

This will take out any temperature variations with different flows
around the house due to taps being turned on.

You can easily control flow by virtue of using a smaller diameter hose
or even restrictors if need be.

We have an Aqualisa "Aquavalve 609" thermostatic mixer in one bathroom and
a
Mira "New Excel" in the other. These are both run from a large (Eco
Hometec)
fully modulating condensing combi.

The Mira is FAR better than the Aqualisa at regulating the temperature
when
other taps or toilets start taking water. The Aqualisa typically runs very
cool for up to I'd guess around 15-20 seconds, whereas the Mira almost
instantly adjusts so you can hardly notice a temperature drop.

The Excel has intregrated flow control. This reacts quite fast.

This may be due to something in the installation, but I'd be very
surprised
as the HW and CW supplies to both showers are taken separately from the
boiler and CW feed down dedicated 22mm pipes that are not teed to anything
else (as per earlier recommendations a while ago by "IMM" or the very
similar "Adam" who mysteriously disappeared about the time that IMM
appeared
in this NG).

Regards,
Simon.
