Heating water for showers, laundry and washing makes up more than a third of an average household's energy use, so it is important to heat water efficiently and choose the best energy source and hot water system for your needs. See below for some tips on helping reduce your hot water use.
- Take shorter showers, 1 minute less can save enough electricity to run a standard TV for 4 hours and 2 minutes less can save up to $100 a year.
- Shower timers can be helpful
- Install a low flow showerhead, prices start at less than $20, to save up to $140 a year.
- Choose the system with the lowest running costs
- For large electric tanks, connect to off peak supply to save up to $300 a year: home owners contact an electrician/accredited service provider; renters seek permission from your landlord. Installation costs apply
- Switch to gas, solar or heat pump and reduce greenhouse gas emissions by up to 75%
- Front-loading washing machines use less water than top-loaders, so if you must wash in warm or hot water, a front-loader is the more energy efficient option
- Washing your clothes in cold water can reduce energy use by up to 80% and save you up to $60 per year.
- A half filled dishwasher uses the same amount of energy as a full one, so wait until you have a full load before starting
