Ripple / Product design


Our daily showering water is usually heated up to 40°C~45°C, and only about 8°C is used during showering, the rest is all wasted.
Ripple is a product that helps save waste heat of the warm showering water by exchanging heat with the clean cold water in the pipe. Simultaneously, the blue LED lights will shine acording to the speed of the water which goes through the holes on the blue lines, the brightness will remind people to save water. The electric energy is transformed by kinetic energy of the falling water.
The accidented surface of silic gel is designed to avoid slip and can also give feet a massage.
