Shower not hot enough - Replace can?
Al
half way. Now it's only just hot enough turned fully up.
I'd replace the whole unit, but it is an obsolete model, and I don't want
to fit anything larger such as a t60i. So I'm planning to replace the can
as I assume it's scaled up (we have very hard water). Sound reasonable?
Should I replace the stabiliser valve while I'm at it?
If it is a buildup of scale, can I descale the 'old' can and keep it as a
spare?
Oh, flow rate is fine - Plenty of pressure. It popped it's PRD ages ago
because I hadn't descaled the shower head for ages. Occasionally it trips
it's MCB (maybe twice in the last year).
Any other possible causes that I haven't thought of?
Cheers,
Al.

Don't forget incoming supply temperature drop. I'd say that it's more or
less "normal" for electric showers to be less effective at this time of
year.

It's just been the coldest day so far in 2009?

The mains water temperature has dropped tremendously over recent weeks,
from the 16 or so degrees down to the 5 or 6 degrees now. As the input
temperature decreases, so the water has to flow through the shower much
slower to achieve the same output temperature as before.
If the shower has two options for Kw, try both and make sure the higher
rating makes the water warmer. That will prove both element sections
are functioning.
Scaled up, would mean a poor flow of water rather than a poor flow of
heat.

Shouldn't that drop the flow rate (to a trickle!) rather than make it
run cold?

Depend on the shower I guess. Most of the ones I've used have a
"temperature" control knob that is actually a flow control. The slower the
flow through the heater, the hotter the water. Consequently, if you use the
same "temperature" setting summer & winter, you will get the same flow but a
lower temperature in winter.
More sophisticated ones might actually use thermostats & the like but not
the ones I've used.

Either way the shower quality is reduced presumably. My 8.5 kw is now
only just warm enough, but I seem to remember it being hotter a few
years back when we first installed it. For ￜ60 I'll replace it rather
than attempt a descale

Our shower has an actual temperature setting dial - no adjustable taps
at all. You set the temperature you want and it adjusts Kw in and water
in, to achieve that temperature. In winter it runs maximum Kw and
adjusts the water input down to get the temperature. In summer it
allows full water flow and decreases the Kw input. If the water
pressure changes, it adjusts to cope with it.
Pretty much set and forget. Touch a button it runs, touch another it
stops - turns the element off, continues running the water for a few
seconds to cool itself down, then stops.
Very, very rarely its processor crashes and needs to be power cycled to
reset it.

Scale doesnt make any difference to the amount of heat delivered to
the water. What's controlled is the amount of power the element
produces, not what temperature sid element runs at. Scaling means
higher element temp but same power delivery

Do you remember the days when you could turn a TV on and it took maybe
a minute for the valve to warm up and the picture to appear? Then came
transistors and the picture appeared in just a few seconds. Now we wait
a minute for the digi TV to boot itself up and the picture to show.

I remember having to turn the radio on at 12.55 for the 1pm news

I know. Their timekeeping's gone to pot, these days.
