Energy Saving Tips: Water
Electric Showers
Electric showers have the biggest draw of electricity in the house (about 8kW)
By cutting down from a 20 minute shower to a 5 minutes shower you could save ££££s
| Minutes | kW per shower | kW per year* | £ per year* |
| 20 | 2.6 | 540.8 | £81.12 |
| 10 | 1.3 | 270.4 | £40.56 |
| 5 | 0.67 | 135.2 | £20.28 |
(* based on an 8kW shower, taken 4 times a week and at a cost of 15p per kWh)
Mixer Shower
It also costs money to heat the water in a mixer shower
– Why not waste less water by fixing water efficient shower heads and taps?
How much water does the average house use in a day?
150 litres per person per day
How much could this be cut if water saving flushes, taps and showerheads were used?
It would be cut by about a third
How much is wasted through people brushing teeth, washing hands, leaking taps, etc?
Teeth – If you leave the tap running it wastes 6 litres per minute, so turning the tap off when brushing can save around 12-18 litres per day.
Washing hands – Very little water is wasted here but if you put in the plug instead of washing under running water, it could save around 3 litres per wash
Leaking taps – Waste at least 5,500 litres of water a year; that’s enough water wasted to fill a paddling pool every week for the whole summer. Mending your dripping tap washer could save you over £18 a year
