When it comes to hot water systems in Australia there are a few different options.
Heat pumps have gained popularity over the last few years, however there are a few things to consider before changing your current hot water system.
The most common types of hot water systems in Australia are:
- Gas or Electric storage tank
- Gas or Electric instantaneous
- Solar gas boosted
- Solar electric boosted
- Electric heat pump
The best option for your household will depend on a few factors including:
- The number of people in your household
- How you use hot water
- Your energy tariffs
- Climate where you live
- Efficiency of the system
According to data released from Sustainability Victoria in January this year, a high efficiency solar with gas booster hot water system is the most economical to run. It also has the added advantage of having the lowest Greenhouse Gas emissions over a 10-year period compared to any of the other options listed above.
Sustainability Victoria have calculated estimated annual energy costs and 10-year greenhouse gas emissions for the various types of hot water systems for 1 person to 4 person households. They have compared high efficiency models with standard for each hot water system type as well as for peak and off-peak tariff options. If you’re unsure which system is going to be best for your household, Immerge Group can help.
High efficiency heat pumps come in second according to Sustainability Victoria, however reviewing your current tariff from your electricity retailer will enable you to make an informed decision about the likely savings you could expect. Electric heat pumps use significantly less electricity than an electric storage or electric instant hot water system. So, if gas is not available at your property, upgrading to an electric heat pump could save you money on your electricity bill.

If you’re planning or currently building a new home, opting for a solar gas boosted system is likely going to be your most cost-effective choice in the long run. The upfront price is higher compared to some of the other options, but the long-term savings on your energy bills and lower Greenhouse Gas emissions make it a great option when building a new home.

If you’re eligible, changing over from your existing inefficient hot water system to a new system from their approved products list could save you $1,000 on the installation cost.
