Zypho® Shower Drain Heat Recovery System is an innovative green solution that captures heat from shower wastewater to save energy and reduce CO2 emissions. As warm used water flows down the drain, it passes through a heat exchanger that preheats the incoming cold water feeding the shower or water heater. This system requires no power or electronics and can save between 30% and 75% of hot water energy depending on the model.

Models include the iZi30 (easy to retrofit), PiPe (vertical solution), and PiPeDW (double wall). Each is compact, plumber-friendly, and compatible with bathtubs, linear drains, or raised showers. Zypho units improve a building’s energy rating and comply with green construction codes across Europe. The system reduces CO₂ emissions and supports the transition to nearly zero-energy buildings (nZEB). With no moving parts, Zypho is reliable and maintenance-free, and includes built-in safety features to prevent contamination. It is widely adopted in hotels, apartments, public housing, and retrofitted energy efficiency upgrades. The product offers a return on investment in under five years in many cases.
