After home heating, water heaters use the most energy in the home. Take advantage of the small things you can do to maximize your savings.

To save hot water, take a shower instead of a bath. A typical bath will use about 75 litres of hot water. On the other hand, a shower with an efficient showerhead will use about half of that.
Fix any leaky faucets. One constant drip can waste up to 182 litre-sized bottles per week. If it's a hot water faucet that's leaking, you're literally sending your energy dollars down the drain.
To save water and energy, install aerators on your kitchen faucets.
Wrap your electric water heater with a blanket made for that purpose to help reduce heat loss.
Insulate your hot water pipes.
