Water use & heating
Water and home heating account for most of your home's overall energy costs.
Reduce your water use and save money on your energy bill. Low-flow showerheads can save up to 7,200 litres of water a year, and by using less hot water you can save up to $30 on your energy bill and up to $30 on your water bill.
Install water and energy saving devices such as low-flow showerheads and faucet aerators to reduce your water heating costs. Find out how you can get the devices for free through the Water and Energy Saver Program.
Another way you can save money on water heating is by installing a drain water heat recovery system. Drain water heat recovery systems can save you up to 25 per cent on your water heater's energy consumption. This leads to a longer life for your water heater and more savings on your energy bill.
Choosing a water heater
The decision to replace a water heater often needs to be made in a hurry. Although standard water heaters usually last about 7 to 12 years, they can fail at any time. This may occur at night or on a weekend when there is little time to comparison shop.
