Water, Energy & Carbon Savings

Mixers showers waste too much water and use precious resource. A Kelda shower uses 5 litres per minute of water compared to a standard 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. Kelda Air-Powered™ showers typically save around 50%  –  60% of water and energy compared to conventional showers, setting the highest standards in water efficiency. Installing a Kelda shower can save a family of four around £270 per year, lowering household bills by as much as 20%.

Improved Dwelling Performance

Kelda is working with the Building Research Establishment (BRE) to recognise Air-Powered™ showers within the Product Characteristic Database (PCDB)  /  Appendix Q of SAP. The Standard Assessment Procedure (SAP) is used for calculating the energy rating of new dwellings.

Our aim is to ensure we develop the most efficient showering solutions that will improve your homes performance to reduce costs and the impact that we make on the planet.

Building Regulations (Water Efficiency)

Water for showering and bathing accounts for 41% of the total household consumption, according to Southern Water.

Part G2 of Building Regulations establishes standards on water efficiency in dwellings. A Kelda shower reduces the current ’maximum consumption’ or ‘flow rate’ requirement of 10 litres/minute by 50% (to meet the standard ‘notional’ level of 125 litres/person/day) and by 40% where the more stringent 8 litres/minute (‘higher’ optional level of 110 litres/person/day) is requested.

Water Infrastructure Discount

Water companies use a lot of energy to treat water, pump it to and from the home and then treat it before returning it to our rivers. Showers which use less water reduce this impact.

In response to water scarcity. If you are developer, Water Companies, such as Anglian Water, are incentivising developers, up to £740 per plot, to build new houses to a water efficiency standard of 100 litres/person/day (10 litres below the optional ‘higher’ level).

Water & Safety Standards

A Kelda shower complies with all UK regulatory standards including the Water Supply (Water Fittings) Regulations.

For your added safety and peace of mind our thermostatic mixers comply with TMV2 approvals, meaning the shower water temperature will not exceed 41° C to prevent scalding.

Heating System Design

Using 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.
