Water
Air-infusion nozzles keep the spray full while limiting flow to about 5.7 litres a minute. Using less hot water means you heat less water, and if you’re on a water meter, you pay for less water too.

Your savings, honestly explained
The Energy Saving Trust estimates that a typical family replacing an inefficient shower head with a water-efficient one could reduce their combined heating and water bills by around £65 a year in Great Britain (£25 in Northern Ireland). Water bill savings assume a water meter, using an average of water and sewerage charges across England and Wales. Heating savings depend on how your water is heated.
*Price ÷ estimated yearly saving, only if the full saving applies in your home. It doesn’t account for future energy prices.
