Energy usage through water heating can account for up to 25% of all home power usage. Therefore it’s a great idea to see where savings can be made, not only to reduce usage of natural resources, but also to save dollars when the quarterly bill hits the mailbox.
Right sized water system
Having the right system for your household does not only ensure that water is available when required, but also ensures water isn’t heated when it’s not needed.
If you have a storage hot water system, the following are the approximate sizes of tank per number of residents.
- 1-3 People > 250L
- 3-5 people > 315L
- 5-8 People > 400L
It makes sense that keeping 400L of water at a ‘ready to use’ temperature for only 2 people is a waste of energy.
So you’ve got the right sized system for your household, now it’s a great idea to make sure you’re on the right tariff. Have a think about when you use the most energy, if at home during the day you may be using the most power during peak hours. If you’re an early riser, or cook and take showers in the evening, your may be able to take advantage of off-peak rates.
Consult your energy provider and discuss your plan options, if you’re not satisfied, consider moving to another supplier.
Fix leaking taps
A tap dripping only 1 drop per second equates to around 9,000 litres of water per year. It’s this is a hot water tap, not only is water being wasted, but the heating costs can equate to $100 per year, that’s literally letting money drip down the drain.
Energy efficient shower head
An energy efficient shower head is an inexpensive way to save energy. Standard showerheads use between 15 and 20 litres of water per minute, compare this with an energy efficient showerhead at only 9, and water use can be cut in half. This can save thousands of litres of water per year, and where water is being saved, money is too.
Wash in cold water
A household typically uses around one third of its water consumption in the washing machine. These appliances either are cold-fill, and the machine heats the water, or they take the water hot from the supply – using power every time. If upgrading your machine, consider a front loader which uses less water. Another way to save water is to wash cold, which of course requires no water heating. There are plenty of detergents on the market now especially for cold washes, so even if you can’t wash cold every day, lightly soiled clothing can easily be refreshed without heating water for washing.
