Optimize your bathroom energy consumption and save on your energy bill

Sustainable and with low environmental impact, this solution will allow you to optimize the energy performance of your shower.


Recognized as a Renewable Energy (RE) solution, this highly innovative system allows to recover the waste heat of the water used through the shower drain, preheating the cold water from the mains, sending it to the thermostatic faucet, thus reducing the energy demand for the generation of hot water needed for shower use.

It is a versatile system suitable for any type of shower (prefabricated, traditional shower, bathtub)

The saving are equivalent to the saving generated by solar panels (8m2)

Passive system: no power, no wire needed


What is a shower heat recovery unit?

The Waste heat is the thermal energy that is neither recovered nor valorized.

The shower heat recovery system recovers waste heat (also called the “fatal heat”) from the water used and drained down the shower drain.

The recovered waste heat is used to pre-heat the cold water during the shower.

It is an innovative system recognized by the European Union as a Renewable Energy (RE) solution.
