Kelda Technology

Kelda Technology is the pioneer of water-in-air shower products that halve water usage and water heating costs through patented shower technology.

Our vision is to create shower products that make water usage better for everyone, everywhere – for businesses with high-volume water requirements, for consumers demanding an improved eco shower experience and for those around the world in water-scare and water-stressed regions where every drop counts.

As a winner of the Rushlight Energy Award in 2015 and supported in early phase development by the UK Department of Energy and Climate Change, our technology has been developed in partnership with the University of Southampton and endorsed by Waterwise, a water industry advisory body.
