(i)
These curves are for the specified outputs at 230 and 240V.
(ii)
All heaters 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 a Mira Elite 8.5 on full power setting with cistern-fed 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.
