Many of us may not realise that our water use at home contributes to our energy bills. Thankfully, to help shine a spotlight on this issue, the Energy Saving Trust have created a really information article offering a variety of in-depth information.

Saving water can reduce your water bill (if you’re on a water meter), reduce your energy use and bills, reduce the impact on your local environment, and reduce carbon dioxide emissions by using less energy to pump, heat and treat the water.

Water is intrinsically linked to energy. But most of us underestimate the energy-water companies need to treat and pump water into homes – Scottish Water is the largest user of electricity in Scotland.

When we use water, we are 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 4% the UK’s total carbon dioxide emissions.

  • 330 litres a day – Each household in the UK uses on average around 330 litres each day.
  • 20% of the heating bill – About 20% of a typical gas-heated household’s heating bill is from heating the water for showers, baths and hot water from the tap.
  • £135 a year – This costs on average around £135 a year.

Water savers vs. water wasters

Which one are you – A or B?

Heating water

The hot water in your home is likely heated by one of two methods – a boiler or immersion heater – unless you have installed a renewable heating alternative such as a heat pump.

Immersion heater

In some homes, particularly those with electric storage heaters, water can only be heated by immersion heater. There may be 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 off-peak electricity. The top heater is used to provide additional hot water during the day if required, using expensive peak rate electricity.

Tip: Do not leave a peak-rate immersion heater on all day and all night. You will waste a lot of money keeping water hot when you don’t need it.
