Flow Rate Graph
1.
These curves are for the specified outputs at 240 V.
2.
All appliance heating elements have a manufacturing tolerance. Flow rates may
be above or below those shown on the flow rate graph.
3.
The left-hand axis shows temperature rise.
Temperature rise = (Showering temperature) - (Supply water temperature)
Example:
For the Mira Zest 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.
