(i)
These curves are for the specified outputs at 240V.
(ii)
All Mira Go heating elements have a manufacturing tolerance. Thus flow
rates can be above or below those indicated.
(iii)
The left-hand scale is temperature rise. (Temperature rise = Showering
temperature minus the incoming cold water temperature.)
Example:
For the Mira Go 8.5 kW on full power setting with an incoming water supply
at 10°C and a showering temperature at 42°C, the temperature rise is 32°C. The flow
rate is therefore, 4 l/min.
How Your Electric Shower Works
The higher the temperature the lower the flow rate will be through the shower head and
vice versa. This flow rate will also be affected by the incoming cold water temperature.
The graph below allows you to determine the flow rate through the shower head (see
example).
