What is the domestic hot water flow rate for the I 24 at 35°C temperature rise?

The I 24 delivers a nominal DHW flow rate of 9.9 litres per minute at a 35°C temperature rise. The DHW flow rate is automatically regulated to a maximum of 9.9 l/min (2.2 gpm). Due to system variations and seasonal temperature fluctuations, DHW flow rates and temperature rise will vary, requiring adjustment at the draw-off tap. (Page 8)
