Showers are amongst the most water intensive devices around us and are used everywhere in the world – in gyms, leisure centres, hotels, student accommodation, hospitals and of course at home. And today these millions of showers are wasting billions of litres of water, the world’s most precious resource.
Traditional showers have barely changed for over 40 years – they’re massively inefficient and use twice as much water as they should do. Flow rates of 9 litres a minute in gyms and 15 litres a minute in hotels are not unusual – a typical gym will spend over £10,000 each year on water supply and disposal alone, a large hotel over £15,000 and a household over £500. Kelda Technology Shower Systems have reinvented how showers operate, halving water use and halving water costs without compromising the shower experience.
We’ve taken the traditional shower and rebuilt it from the ground up. Instead of putting air into water, we inject water into an air flow to produce the world’s most efficient shower. The Kelda Shower System carefully manages the optimum mix of water in air, which is then accelerated using a jet-type nozzle to create a spray force that has over two and a half times the power of a standard shower.
The University of Southampton demonstrated the Kelda Shower System is 20x safer than an aerating shower in guarding against harmful legionella when comparing the generation of aerosols which carry the legionella bacterium. Using a laser diffraction technique, water droplet sizes from different shower heads were measured and it was shown that the Kelda shower produced fewer particles of the size necessary to contract the disease.
