Have had one of these

http://tinypic.com/r/dnf4le/9Â*Â* (10.8Kw)

for the last 10+ years, used daily.

3 years ago or so the water temperature started to play up (would turn
cold suddenly when in use), and at the advice received here I cleaned
the filter on the water inlet, which fixed it, and no problems since.

Yesterday it started to misbehave again: under Medium or Low setting the
water is completely cold. When set to High it almost reaches acceptable
temperature when the dial is on max, but not hot enough. Anything below
that is pretty much cold.
Usual setting for this time of year is around 1, perhaps 2 o'clock.

I tried to clean the (very dirty) filter again, but it had no effect.

Any idea what to try next please?

How many elements in the heater tank does it have? Having three
settings suggests three. It sounds as if at least one, and possibly
two, have failed in some way, either gone O/C or the switches have
failed.


But even when it is set to High the water is only lukewarm when the dial
is set to max...Â* So two elements are completely dead and one "half dead"?


Also, just noticed that Mira offer a repair service. They are not clear
about pricing (£80 call out charge + parts?).
A new equivalent shower is £220, and as long as the plumbing/wiring
haven't changed (very likely) I am happy to replace it myself.

Is it worth fixing considering its age, or has it reached the end of its
working life and other parts are likely to fail "soon", i.e. a new one
would be a better solution?
