Hot water performance
Hot water flow (l/min) @ 30 degrees The flow rate is given according to a certain temperature achieved, assuming that the boiler increases the temperature of the water by 30, 35 or 40 degrees. The more the water temperature is increased the lower the flow rate. It is not applicable to heat-only or system boilers which store hot water in a separate cylinder. n/a
