How to Save Money and Energy with Your Water Heater

A water heater in Australia can use a lot of energy depending on its efficiency. Fortunately, there are a number of practical steps you can take to make your water heater more efficient and reduce your energy bills. This blog post shares some maintenance tips and optimal settings, as well as information on when to upgrade to a more efficient model.

Maintenance Tips

• Insulate Your Water Heater – Wrapping your water heater tank with an insulating blanket can reduce heat loss by 25-45%, saving you between 7-16% on your water heating costs. This is particularly effective for older models.
• Flush the Tank Annually – Sediment build-up in the tank can reduce your water heater’s efficiency and lifespan. Flushing the tank at least once a year can help remove sediment, ensuring efficient operation and prolonging the water heater’s life.

Optimal Settings

• Set your water heater to 50°C. This is hot enough for most household needs and can reduce energy consumption by 6-10% compared to the standard 60°C setting.
• Consider installing a timer that allows you to turn off the water heater when it’s not in use, such as overnight or when you’re on holiday.
• Install low-flow showerheads and faucets to reduce your hot water use.
• Wash clothes in cold water, and avoid running dishwashers and washing machines with half loads.

When to Upgrade

Water heaters typically last about 10 to 15 years. If yours is approaching this age, it may be time to upgrade to a more energy-efficient model, such as an instantaneous water heater. Newer models are more efficient and can save you a significant amount of money in the long run. When shopping for a new water heater in Australia, look for models that meet strict energy efficiency guidelines, allowing you to save hundreds of dollars over their lifetime compared to standard models.
