Hyco Rho Instantaneous Inline 4.4 kW – IN44
Part No Description
IN44 Rho Instantaneous Inline 4.4 kW
Usage:
• Supplies hot water to a single outlet
• 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
• 4.4 or 6.0 kW power rating
• Compact space saving design
• Intended for use with spray head taps with removable M22/ M24 nozzles
• Compatible tap available separately
• Not suitable for use with taps with thermostatic mixing valves
Thermostatic Model Only
• External electronic thermostatic control accurate to the nearest degree
• Blue 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 30°C and 48°C
• After power off/ on the unit will recall the last usage outlet temperature

Technical Specification
Outer Casing
Easy clean high impact ABS
Heating Element
Bare-wire heating system (3 nickel chrome heating elements)
Controls (Thermostatic Model only)
Temperature display (°C)
Power on/ off button
+/- controls allow the user to set the required temperature
The temperature display will flash if the set temperature cannot be reached.
Taps and Tap Spray Nozzles
Intended for use with spray head taps with removable M22/ M24 nozzles. Compatible tap available.
Important – the supplied tap spray nozzle must be fitted in the tap for best performance.
Safety
Overheat temperature protection 80°C.
Thermostatic model – water temperature controlled to maintain user selected temperature between 30°C and 48°C as water pressure conditions vary.
IP Rating
IPX4
Installation
This appliance must be installed in a frost free environment.
The heater should be located as close as practical to the hot water outlet to avoid unnecessary heat losses through the pipework.
Plumbing
Must be installed by a suitably qualified person.
Minimum flow rate 2.0 l/m.
Minimum water pressure 1 bar.
Maximum rated pressure 7.5 bar.
Water resistivity ≥ 1300 Ωcm.
Water Connection
Inlet/Outlet 2 x 1/2″ BSP male (40mm apart centre to centre).
Fittings required (not supplied): 2 x 15mm compression to 1/2″ BSP female adapter.
Suitable for use with pre-heated water e.g. solar heating systems subject to maximum inlet water temperature 60°C.
Electrical Connection
Installation must comply with current IEE regulations.
Single phase. Fuse rating guide 19 amps for 4.4 kW and 27 amps for 6.0 kW.
The product should be connected to the fixed wiring of the property via a suitably rated isolating switch with contact separation of at least 3mm in all poles.
Cable pre-wired (0.7m).
Approvals
CE, WRAS
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/m
Application
Recommended temperature for hand washing or shower 38°C.
Recommended temperature for a kitchen sink 50°C.
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
Check the flow rate and water temperature will be adequate for your application using the chart and tables provided.
Take into account that the incoming water supply temperature will be lower in the winter than summer.
