Hi all,

How quickly do thermostatic valves adjust to a sudden loss in pressure
in one pipe?
Let me explain-
In my flat I have a combi boiler for the hot water, mains pressure CW
for the kitchen *but* a CW storage tank for the bathroom (apparantly
first thing in the morning the pressure was very poor). Unfortunately
the ceilings are very low so the head between the top of the CW in the
tank and the shower head is at best around 50cm. Not exactly great
then.
I'm in the process of fitting a single vane booster pump to the bath /
shower CW supply.
However, my worry is this: if the water pressure really is rubbish I
run the risk of using up all the water in the cold water tank and
getting scalded.
If I upgraded (from a standard mixer)would this help- would a
thermostatic shower unit (like the Pegler Fanfare sold in Screwfix)
adjust in time or would I be better with a hot water isolation valve
(electrically switched) run off an electronic float switch in the cold
water tank.
Thanks for any advice,

Ben
