Hot water
Hot water accounts for 25% of household energy use and around 6 tonnes of greenhouse emissions.
By replacing your old showerhead with a water efficient one (see video for instructions) and reducing your shower time to 4 minutes you can save on your energy bills too.
Another important step is to replace your old or inefficient hot water system. If you're considering a solar hot water system, you might be eligible for our bulk buying program, Delivering Clean Energy Solutions.
Solar hot water systems work by harnessing the energy of the sun. Water is heated as the sun passes through ‘solar collectors’ - flat dark coloured plates designed to warm in even minimal sunlight. The water is then stored in an insulated tank, either on the roof next to the solar panels (called a close coupled system), or in a tank which sits in or beside the home (called a split system). If needed, electricity or gas can then boost the water to reach the desired temperature - this means you never need to run out of hot water.
Solar collection panels can be retrofitted onto some kinds of hot water systems, and this costs less than replacing the whole system. If you live in a heritage precinct it is best to seek advice from your council on planning requirements.
Both State and Federal Governments are offering rebates for solar hot water. For more information see our Rebates fact sheet.
