|RECOMMENDATION||HOW WE CALCULATED THE SAVINGS|
To save energy turn off fridges that are not fully utilised and leave the door ajar. You could save between $100 and $200 a year in electricity for every fridge you turn off.
Based on a 3.5 star family-sized fridge.
A 3.5-star fridge instead of a 1.5-star fridge could save you a cool $150 a year.
Based on a comparison of energy usage for a 1.5 star and a 3.5 star family-sized fridge.
A water efficient showerhead (3 stars or better), can save both electricity and water. These days most models give a quality shower and could save you up to $200 each year on your hot water heating costs.
Based on a household of four people taking one 4 minute shower per person per day, with the hot water connected to Tariff 33.
Change your electric hot water system to an economy tariff and you could save between 15% and 44% on electricity running costs.
Based on comparing notified prices for Tariff 11 with Tariff 31 and 33, effective 1 July 2015.
Your electric hot water system can contribute to up to 30% of your electricity costs.
If you're thinking of buying a new washing machine, choose a more energy-efficient front loader, instead of a top loader. You may pay a little more up front, but you'll save around 50% on electricity running costs.
Based on standard storage or heat exchange electric hot water system in a household averaging 10 kWh per day on Tariff 33.
Based on comparing a large automatic 600W top loader with a large automatic 300W front loader.
Use the sun to dry your clothes instead of using the dryer. Just two loads in the dryer each week could end up costing you around $50 a year.
Based on running two 45 minute loads each week in a 2.4kW dryer with 5kg capacity.
Reducing your pool pump running time by just one hour a day could save up to $100 a year.
Based on a 1 kW pool filter on Tariff 11 Domestic.
Upgrade your pool pump to a 5-Star Energy Efficient Pool Pump and save up to 80% on your pool electricity running costs.
Based on a 350W 8-Star rated pool pump compared to a 1.1kW fixed speed rated pump running 6 hours per day for 365 days per year.
Change your pool pump from Tariff 11 to Tariff 33 and you could cut your pool electricity running costs by approximately 15%.
Based on comparing notified prices for Tariff 11 with Tariff 33, effective 1 July 2015.
Stick to 25°C in summer and 18°C in winter. Every one degree cooler in summer adds around 10% to the amount of electricity the air conditioner uses.
Based on an ambient temperature of 30oC. When the air conditioner is set at 25oC it will cycle on for 70% of time. On cycling will increase as the air conditioner temperature is lowered until when set at 20oC when the air conditioner will cycle on for 100% of the time. Results may vary depending on whether the air conditioner is sized correctly for the room it is operating in, windows and doors are shut, blinds are closed and climatic conditions in your area etc.
Most old air conditioners are noisy and cost a small fortune to run. Replace your old style system with a new PeakSmart split system inverter and save.
Must be compliant with Australian Standard AS4755.3.1. Go to Eligible PeakSmart air conditioners for a complete list of applicable air conditioners.
