These curves are for the specified outputs at 240V.
(ii)
All Mira Sprint 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 Sprint 7.5 kW on full power setting with an incoming water supply
at 10°C and a showering temperature at 45°C, the temperature rise is 35°C. The flow rate
is therefore, 3 l/min.
