Easy to install

ZYPHO systems are extremely easy to install, requiring no power connections and containing no moving parts. What’s more, unlike many low-carbon technologies, ZYPHO installation requires no specialist professional skills beyond those of a regular plumber.


Once installed, ZYPHO passively improves the efficiency of the shower by around 30 – 75%, (depending on application and model).

Less energy consumed = Fewer CO2 emissions.
