iZi 30 High Flow and iZi 40 Eco Shower

Heat transfers from the shower’s hot waste water to the incoming cold mains supply. This heated water can be directed either to the shower tap, the water heater or both.

Horizontal shower drain waste water heat recovery solutions include Zypho iZi 30 High Flow & iZi Eco Shower

In this example, 40°C hot water transfers up to 50% of its heat to the incoming 10°C cold water from the mains.
