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.
