Kelda Showers


Kelda are the inventors of high-efficiency Air-Powered™ showers that reduce carbon emissions by using significantly less water and energy. Designed and manufactured in the UK a Kelda shower is proven to deliver a better shower experience as low as 5 litres/minute.Company HistoryOver the years Kelda’s innovative showers have been vigorously tried and tested in the most demanding real-life environments, such as the prestigious London Aquatics Centre, to ensure they can withstand the pressures of high usage, In every case, Kelda’s Air-Powered™ showers have proven to reduce water consumption, energy costs and carbon emissions. With 100% positive feedback from customers Kelda is proudly demonstrating that it is possible to have an invigorating shower at lower flow rates.Kelda’s Air-Powered™ shower technology may seem new, but it is the result of over 10 years of development–drawn from cutting-edge aerospace and automotive engineering.Today, Kelda has a number of global patents and patent applications protecting its technology and are one of very few companies in the world focused on reducing water consumption through shower design.Technology OverviewConventional ‘aerating’ showers use the Venturi principle to restrict flow and draw atmospheric air into the water through a small hole in the showerhead. This is a very cheap way to reduce the mass flow of water, and aerate it to change the ‘feel’ of the shower, but has no measurable boost in force or performance, regardless of flow rate.In contrast, Kelda’s patented Air-Powered™ showers use the principles of fuel injection technology. Each shower features an intelligent microprocessor and powerful digital fan which controls the delivery of water and air to the showerhead. Within the showerhead, water is injected into a high-velocity air stream where it is broken up into 100s of droplets that are 2.5X the size of a standard shower. Larger droplets yield larger momenta providing the sensation of more spray pressure, making less water feel like so much more. With 15X more impact than a standard shower, a Kelda shower is more effective at rinsing shampoo out of even the thickest of hair.By installing water and energy-saving products such as Kelda Technology’s water-efficient showers it is possible to significantly reduce carbon emissions and save money on bills – with the benefit of having a better showering experience.HighlightsEfficient CleaningCompared to standard showers, Kelda’s MACRO droplets are larger–yielding larger momenta. This gives the sensation of more spray pressure. With 15X more impact than a standard shower droplet, a Kelda shower is more effective at rinsing shampoo out of even the thickest of hair.Sustainable ShoweringMixers showers waste too much water and use precious resource. A Kelda shower uses 5 litres per minute of water compared to an average shower that uses 10. This means half the water and energy and therefore fewer carbon emissions. A Kelda shower maximises every droplet to reduce waste.Immersive ExperienceImagine a shower that is designed for you and the planet. A Kelda shower atomises water into 100s of perfectly engineered MACRO droplets to ensure you feel every single one of them. We may use less water to help conserve the world’s most precious resource but we haven’t compromised on experience.Heating System DesignUsing less water is not only a key requirement for compliance but can help generate savings in the size, capital cost and maintenance of your heating system. In the case of new build–less water allows the specification of a smaller hot water storage cylinder–a key consideration when using heat pumps, where 200-litre capacity is commonplace.Benefits:Sustainable Air-Powered™ shower technology.50%-60% savings in both water and energy bills – around £255 per shower per year for homeowners, and £358 per shower per year for gym owners.Meet/exceed all building regulations re. Part G and Part L (Future Homes Standard).Air-Powered showers are a primary energy reduction technology – reduces carbon emissions by 10% (in future SAP 10 calculations).Meet and exceed the RIBA’s 2030 Climate Challenge targets.Major contribution to net-zero carbon targets both in new build and refurbishments.Recognised by Government schemes e.g. Salix Finance.Technology and savings have been verified by the Energy Savings Trust.Despite using less water, we provide an enhanced user experience.Proven to be a more cost-effective solution compared to other competing “green” technologies i.e. insulation/double glazing.

Multiple CPD formats
The Future of Sustainable Showering
This CPD takes an in depth look at the importance of understanding and specifying a sustainable shower system. Topics discussed include the Sustainable Development Goals, current building regulations, current construction and RIBA targets, installation guidance and energy usage. By the end of the presentation you should have a greater understanding of:
- How to identify and specify the best water saving shower for the correct scenario
- The role of showers in contributing towards RIBA net zero emission targets
- The technology behind an air powered shower system
- Commercial and residential shower behaviour
- How to address installation, site and health and safety concerns
