After space-heating, hot water is the largest energy consumer in the
home. By the simple act of recovering heat from waste water, Zypho®
improves the efficiency of the shower by between 31-75%, depending
on the application and model. Perfect for new build or for retrofitting, its
unique, self-contained mechanism requires no mains connection or


Zypho® improves the efficiency of the shower by between 31-75%,


Most showers send waste water down the drain at 40 °C – a major
waste of energy. With Zypho®, the outgoing waste water is run against
a copper coil of incoming fresh cold water. While the two streams are
kept physically separate, heat passes from the waste hot to the fresh
cold, effectively recycling the heat and lightening the load placed on
the hot water generation system. The pre-heated fresh water can
be directed to the shower tap, to the water heater, or to both.

Waste water heat recovery systems, that require no power, no wires, no batteries – and no hassle!

These systems are a very easy retrofit, or are perfect in new builds, where Zypho systems earn some of the easiest SAP points. Either way, with an estimated 10% reduction in residential heating costs and improvement to EPC ratings, Zypho units are a very desirable and effective addition to any hot water system.

Heat transfers from the shower/bath waste water drain to the incoming cold mains supply. This heated water can be directed either to the shower tap, the water heater, or both!

Heated cold water can be connected in one of three ways: iZi to tap and boiler (the most efficient configuration), iZi to tap, and iZi to boiler.
