In a compact kitchen or a busy bathroom, the N'OVEEN IWH150 delivers hot water on demand without the wait or the waste of a storage tank.

Good to know

This unit is designed for single-point use, so it serves one tap at a time. It requires a minimum water pressure of 0.4 bar to activate the flow sensor. Professional installation by a qualified electrician is recommended, and the G 1/2 inch connections fit standard flexible hoses. The heater is not suitable for whole-house supply or simultaneous multiple outlets.
