Ara, Rho and Aquila Instantaneous water heaters are intended for use with spray head taps with removable M22/ M24 nozzles. A tap spray nozzle must be fitted in the tap to control the water flow rate and to provide best performance and energy and water efficiency

Selection Guide

Take into account that the incoming water supply temperature will be lower in the winter than summer

The incoming water temperature can fluctuate dependent on time of year in the UK. Winter may result in incoming temperatures below 10°C, whereas summer water temperatures can be upwards of 15°C. It is imperative this is taken into account

For example the heater could deliver 42°C water in the summer (with an incoming water supply temperature of 15°C). The same product with the same flow rate would only be able to deliver 37°C in winter (due to a lower incoming water temperature of 10°C). The delivered temperature will be even lower if the incoming water supply temperature is less than 10°C

Check the flow rate and water temperature will be adequate for your application using the chart and tables provided
