SWMBO has decided that our shower is too cold, and I'm sure I've read that
there may be a way to adjust our Mira Excel shower to give a hotter output
temp (if it's not already at maximum). I've managed to get the pdf manual
from Mira's web site, however it's for the newer model rather than the older
version that's in our house.
Can anyone either point me in the direction of the correct manual, or advise
on the procedure? Is there much difference from adjusting the newer models?
The model we have is a top exit and is for concealed pipework.
Thanks in advance for any replies!
Surely they're balanced? Reading the documents for the newer model, it seems
possible to set a range of maximum temperatures by just moving a stop on the
valve (unscrewing then refitting in a new position). I'd just like to know
if anyone's already done this to a mira excel (an older one - gravity fed so
the pressure currently isn't great), and what the procedure is (i.e. does it
have this temperature setting too).
Both hot and cold supplies must have isolator valves on them, if they don't
I'd have some fitted just in case, so wouldn't it be easier to try turning
the cold supply down a bit first to decrease its influence on the shower,
before you go taking it apart to change its internal settings ?
Does this look like your mixer valve:
Yep, that's the one. I've just had a go at it, and it's identical to the
newer model except there's no 'override' button. Looking at your diagram,
you pull off the outer temp knob, undo the screw holding part 410.51 on,
remove said part and turn the shower 'hotter', refitting part 410.51 back
on. I'm not convinced it's hotter, though there's still room for a bit more
adjustment. Will find out later tonight when I have my shower! I also
suspect that there's no isolator valves for the shower, as it's older than 5
years I suspect.
I think the supply pipework would have isolator valves on it, so if you need
that bit extra heat try finding the valves and turn the cold supply water
down a tad and it might help you even more.
Good luck with it.
SWMBO couldn't stand under it at max last night, so hopefully hot enough.
I've adjusted it slightly colder so summer shouldn't pose a problem too. I
don't think there's isolator valves for the shower. My new(ish) last flat
never had them either, but when looking at flats a bit newer I've found
these white plastic panels popping up all over the place, which have the
(now regulatory) isolator valves behind them.
It's best to have isolators to any appliance so they can be maintained
without turning off the whole supply, so it might be in your interest to
have some fitted. I can imagine if you have a fault, a leak or a blocked
shower and have to turn everything off for a couple of days before you get
the parts. SWMBO would not be happy then. :-))
