Features
Features
• Hot water for light handwashing at a single basin only
• Bare wire heating system gives fast heat up time
• Heats the water instantly as it flows through the unit
• Energy efficient – no standing heat losses
• 3.0 kW power rating
• Easy to install, 13 amps connects to standard wiring
• Ideal bought as a set with our hot and cold tap or used with a Vega infrared tap
• Not suitable for use with thermostatic mixing valves or taps or to supply a single lever mixer tap
• Must be used with a spray head tap
• Supplied with a 1.6 l/min flow restrictor which must be fitted to the tap spout giving a temperature uplift of 27°C
• This would give 42°C in summer, incoming water temp 15°C and 37°C in winter, incoming water temp 10°C
• External electronic thermostatic control accurate to the nearest degree
• LED temperature display
• Energy saving – only uses the power required to deliver the chosen temperature
• Heating power adjusted electronically to compensate for temperature, flow rate and water pressure variations
• Temperature factory set at 38°C and can be adjusted by the user between 35°C and 50°C. In normal usage the maximum temperature is 37°C to 42°C.
• After power off/ on the unit will recall the last usage outlet temperature. When power is restored the heater must be turned back on.

Approvals
CE, UKCA
Standard Warranty
1 year parts or replacement warranty.
Temperature Rise
Temperature rise from ambient for an instantaneous water heater (TR)
TR = kW rating x 14.3 / flow rate l/min
Application
Recommended temperature for hand washing or shower 38°C.
Recommended temperature for a kitchen sink 50°C.
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 below using each link.

Energy Efficiency
The Energy Related Products (ErP) Directive and Energy Labelling Directive require that from September 2015 all water heaters in scope meet minimum energy performance criteria and have energy labels which provide the energy ration of the product. The classifications range from A++; this being the most efficient and coded in green to a rating of G; this being less efficient and coded in red.
Such ratings provide transparency of efficiency and a comparable benchmark for water heating products, as standardised European Energy Labels are used.
This website contains the energy class for all relevant water heating products. The full energy label and product fiche information for the Ara can be found below.
