Hyco ARA Thermostatic Instantaneous Inline Water Heater for Hand Basins 3kW

 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
 Compact space saving design
 Compatible taps available separately
 Not suitable for use with thermostatic mixing valves or taps or to supply a mixer 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.

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 38°C.

Ara 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.
