TOTO’s Libella faucet series offers EcoPower self-sustaining hydropower technology. This platform increases the faucets’ ease-of-installation, requiring one controller for both single-supply and thermal-supply models. The faucets’ energy source is completely self-generated. The chrome fittings create their own electricity every time water spins their small internal turbine. Stored in a series of rechargeable capacitors, this auto-generated electricity powers the faucets’ operation. There is no need to hard wire them to a building’s electrical system or for routine disposable battery replacement. The series features both deck- and wall-mount options.
