iZi 30: How does it work?
The system redirects the hot water poured down the drain and uses up to 31%* of this heat to preheat the cold water.
When this hot water is obtained (at 22°C), it is connected to the thermostatic tap (it can also be connected to the heating device at the same time, if desired): this reduces the need for hot water and increases energy savings by up to 25%** compared to a traditional water heater.
In other words, it reduces the hot water energy bill by up to 25%**.
