Shower calculator

Save water, save money and save carbon

As part of our 2007 shower campaign, we have been encouraging customers to save water by spending one minute less in the shower. Doing so could save you around 40 glasses of water.

But did you know that spending less time in the shower will reduce your carbon emissions too?

A lot of energy is required to heat the water to your desired temperature when showering. Therefore, spending one minute less in the shower will not only save water, but will also reduce the amount of gas or electricity needed to heat water, thereby saving you money.

We have developed a calculator that will show you how much water you use when showering over a year, how much energy is required to heat the water, the carbon emissions and finally, how much the water and energy costs over the year.

See how much money you could save…

The calculator will then show you your potential water, energy and money savings if you spent one minute less in the shower.

Please note: The calculated water and energy cost savings are based on data which was accurate in January 2007.

How is your water heated?

Electricity

Gas

How is your water billed?

Metered

Rateable value

If you pay for your water by the rateable value of your property, the amount of water you use won't affect your bill. However, this calculator will still allow you to calculate the cost of heating the water for showering and the carbon emissions.

 

What is the flowrate of your shower? * (l/min)

How many times is the shower used each day?

How long, on average, does each shower take? (mins)

* You can measure the flowrate using a bucket, a timer and a measuring jug.

1. Turn on the shower on the setting you normally use and hold the bucket under the flow of water for ten seconds.
2. Measure the water collected (in litres) using the measuring jug.
3. Multiply the volume of water collected by 6 to give the shower flowrate in litres per minute.
