Just a thought ..... would a timed operation be any good.....? eg when I
get home from work at night (after cycling, so I have a bath every night
to relieve any aches and pains!)  I can switch the hot tap on, set a
timer for 7 mins, and the bath is at a reasonable depth, and generally a
reasonable temperature, obviously depends exactly on water heating 
method - mine is an electric system which heats a storage tank of hot 
water every morning, and when thats exhausted, the water out of the hot
tap is quite cold, but not as cold as the cold tap.... :S If there's an
X10 control there to open the valve, a timed switch off is obviously 
reasonably easy with any of the current controllers... :)

There will also be obvious differences in temperature (In winter the 
cold tap will be colder than in summer) but the volume of water for a 
known valve open diameter should be pretty much constant.........?
