Example:
For the Essentials 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.
(a)
These curves are for the specified outputs at 240V.
(b)
All appliance heating elements have a manufacturing tolerance. Thus flow
rates can be above or below those indicated.
(c)
The left-hand scale is temperature rise. (Temperature rise = Showering
temperature minus the incoming cold water temperature.)
