How does it work

To obtain correct shower water temperature, hot and cold water are combined at the shower mixer tap. Both have different origins: hot water comes from a heating device, for example from your electric or gas water heater, and cold water comes directly from the mains. Depending on the temperatures of cold mains and hot water, you will sometimes need a greater volume of hot water to be mixed with cold water in order to achieve the desired shower temperature.

Easily installed under a shower tray or a bathtub, the ZYPHO utilises the heat from the hot water flowing down the drain. Water entering the ZYPHO will transfer its heat energy to the copper pipe with cold mains water. Cold mains water going through the copper coil of the ZYPHO will, in turn, absorb this heat and therefore become warmer. After having passed through the heat exchanger, cool drain water then exits into the drainage system.

Preheated water goes to the shower mixer and, consequently, a smaller volume of hot water from your heating device is needed to reach an appropriate shower water temperature, which literally means that less energy is used.

The ZYPHO is a safe and clean system where hot shower waste water and cold water supply never mix. While allowing for easy maintenance and cleaning, its unique design also prevents pressure loss and leakage. The ZYPHO is distinguished by its exceptional reliability and durability due to the use of high-quality materials and a technology based on physical principles which are, despite their simplicity, innovative in this field of application.
