Every household in the UK uses on average over 250 litres of fresh clean water every day. About 15 per cent of a typical gas heated household's heating bill is from heating the water for showers, baths and hot water from your taps.
Saving water can reduce your water bill (especially if you’re on a water meter),
When we use water, we are often using energy, mostly to heat the water. Generating energy produces carbon dioxide emissions which is one of the main greenhouse gases causing climate change. Heating water for use in our homes makes up about four per cent of the UK’s total carbon dioxide emissions.
In most homes, the hot water is supplied by the main central heating boiler, either as a combination boiler or some type of boiler which is connected to your hot water cylinder. Most hot water cylinders are ethier vented or unvented. Often there will be an electric immersion heater in the cylinder as well for a emergency back up should the boiler breakdown.
In some homes the hot water is only heated by immersion heaters. There are usually two immersions, one in the top of the cylinder and one in the bottom. Usually the bottom heater comes on at night, and heats the whole cylinder using cheap economy 7 off-peak electricity. The top heater is called the booster to provide additional hot water during the day if required, .
Tips on saving water
Most modern toilets have a dual flush try to use the short flush as much as possible.
On modern toilets the over-flow does not go out-side no more but runs around the inside rim of the toilet pan, so always make sure the toilet pan has no water continually runing around the rim as this could waste a tremendous amount of water over a period of time.
Try to shower more then taking a bath.
You can buy flow restrictors to fit on your taps and showers, which will decrease the flow rate.
Always stop dripping taps as a number of continually dripping taps can waste up to 20,000 litres per Year
In commercial properties the very worst offenders for wasteing fresh clean water are urinals, these can waste thousands of litres of water if not fitted with a urinal flush control. And the very best way of all to save water with urinals is install water-less urinals.
