This post strives to make that choice as simple as possible.

The 4 Types of Hot Water Systems

Hot water represents at least a quarter of the typical Australian household’s energy cost. When looking for the best hot water system on the market, consider the specifics of your house, how your family members utilise water, and various other aspects.

To get the conserving process started, here’s a review of the four types of hot water systems that Australians place in their homes:


Gas hot water systems are similar to electric hot water systems, with the vital distinction being that a gas burner is utilised instead of an element. Because gas systems heat water considerably quicker, they are often smaller than electric tanks.

A continuous flow or instantaneous hot water system is another gas alternative. Because a gas hot water system is energy-efficient and tiny, it is popular and one of the most frequent hot water systems installed in new houses today. The main advantage of this method is that water is only heated when a hot faucet is switched on, so you’ll always have hot water.


Electric hot water systems, like kettles, heat the water using an element within the storage tank. These tanks are available in various sizes and are among the most economical solutions on the market, but more energy-efficient hot water systems are available.

Another electric alternative is a continuous flow or instantaneous hot water system, which only warms the water when the hot faucets are turned on. These systems do not have a high water flow output and may need 3-phase electricity to be supplied.


Solar hot water systems are becoming a more widespread ‘green’ choice on the market. This is also one of the most typical hot water systems installed in new houses since it uses free solar energy to heat your shower instead of electricity or gas. The system will consist of several solar panels often installed on your roof. However, it should be noted that the system will still be linked to power or gas if the weather is not cooperative.

Heat Pump

While officially classified as an electric hot water system, a heat pump is much more energy efficient, costly to install, and noisier to operate. The technique involved is analogous to a refrigerator in reverse. The heat pump effectively collects heat from the air and transmits it to the water, potentially cutting your hot water cost in half.

Which Type of Hot Water System Should You Choose?

Now that you’ve learned about the many kinds of hot water systems and understand you have a lot of options, the next issue is which is better to use: Solar or heat pump? Gas or electric?

Picking up the phone and asking the top plumbers for guidance on your upcoming hot water system investment is the ideal method to make this essential choice.

  • Natural gas is less expensive than electricity, and there are no ‘peak’ or ‘off-peak’ prices to contend with.
  • Natural gas is less costly than bottled LPG.
  • Solar panels must be strategically placed for maximum efficiency and might cost thousands of dollars to install. Several discounts and incentives are available, not to mention the cheap operating expenses, which means you may repay the purchase price over time.
  • Heat pumps must be installed in a well-ventilated environment, which may not be acceptable inside due to the running noise. This style of installation is likewise best suited to warmer climates.
