Instantaneous water heater NOVEEN IWH460 4600W 220–240V, tankless point-of-use, 2.5 l/min, IPX4, LED display

Compact tankless instantaneous water heater NOVEEN IWH460 delivers hot water on demand up to 60 °C with a maximum flow rate of 2.5 l/min. Designed for countertop mounting, it operates from standard 220–240 V AC (50 Hz) and is intended for point-of-use applications where space is limited. The unit includes a cable with plug and features an LED display and lever control for straightforward operation.

Advantages

The heater provides instant hot water without a storage tank, reducing standby energy loss. Its compact countertop design and IPX4 splash protection make it suitable for installation near sinks. The integrated LED display and lever control offer simple, precise adjustment of water temperature and flow. Low maximum flow and adjustable power ensure compatibility with small water outlets and limited electrical supply.

How to use

Install the unit on a stable countertop surface near the water outlet following local electrical and plumbing regulations.

Open the water tap and adjust the lever control while observing the LED display to reach the desired temperature. Do not exceed the specified maximum water pressure and temperature limits.

Usage recommendations

For reliable performance, ensure the electrical circuit can support a 3600 W load and that water inlet conditions do not exceed 600 kPa. If inlet water is very cold or higher flow is required, expect lower output temperature or reduced flow. Regularly check for limescale in hard water areas and follow local maintenance guidelines.
