Types of Electric Hot Water Systems

Storage Tank Systems

Storage tank systems hold hot water in a big tank. These storage units come in many sizes. You can find tanks from 0.4ltr to 400ltr. They are made for all types of houses or flats!

These systems have white and silver colors to pick from. The depth of these tanks is between 95mm to 1840mm, and the height is also between 360mm to 1840mm. It means you can find a tank that fits your needs perfectly!

Continuous Flow ('Instantaneous') Systems

Continuous flow systems, also called electric instantaneous units, give hot water right away. They heat the water as you use it. This means no waiting for a storage tank to fill up with hot water.

But they do not list the brands or sizes of these systems on the website. Information about their color, size, and how much hot water they put out is also missing. So, if you need a lot of hot water at once, this might not be the best choice for you.

Plus side is that it can cut down on your energy bills because it only heats water when needed.

Key Factors

Considerations When Choosing
an Electric Hot Water System

Household Size and Water Usage

Your home size and how much water you use matter. Big homes with many people need more hot water. This means they need a larger system. A small home with fewer people needs less hot water.

So, they can choose a smaller system for their needs. Also, if your family uses a lot of hot water at once, consider this too. For example, do you all take showers in the morning? Then pick an electric system that can meet this high demand.

Energy Efficiency and Star Ratings

Electric options can help cut energy bills. Look at the star ratings to know how well a system saves energy. More stars mean less power used. Less power used means lower costs and less harm on our Earth.

Also, every product listed on web pages like Rheem and Reece has its own star count. You just have to pick what works best for your home and pocket!


Benefits of Electric Hot Water Systems

You can pick from many sizes, which range from 0.4ltr to 400ltr. This means you can find the right one for your needs, no matter how big or small they are! These systems are also good if you care about colour, depth and size because there are so many choices.

They don’t cost much either – prices start at $250 and go up to $2500. A plumber with a license should set up your system for you though, this makes sure that it is safe and works well.

How to Maintain Your Electric Hot Water System

To keep your hot water system running efficiently, here are some maintenance tips:

  1. Regularly check for any leaks or drips from the system.
  2. Inspect the pressure relief valve and ensure it is functioning properly.
  3. Flush out sediment buildup from the storage tank annually to improve efficiency.
  4. Test the temperature and pressure relief valve by lifting its lever and allowing some water to flow through.
  5. Insulate the hot water pipes to reduce heat loss during distribution.
  6. Check the sacrificial anode rod every few years and replace if corroded to extend the lifespan of your system.
  7. Clean or replace the air filter on heat pump systems regularly for optimal performance.
  8. Keep the area around your hot water system clear of debris and clutter for easy access.

If you’re wondering when it’s time to replace your hot water system, there are a few things to consider. First, if your system is very old and constantly breaking down, it might be more cost-effective to replace it with a newer, more efficient model.

Additionally, if your current system is not meeting the hot water demands of your household or you’re experiencing a decline in its performance, it may be time for an upgrade. Another factor to consider is energy efficiency.

If your hot water system has a low star rating and high energy consumption, replacing it with a more efficient one can help lower your energy bills and reduce greenhouse gas emissions.

Finally, if you find yourself frequently repairing or servicing your current system and spending significant amounts on maintenance costs, replacing it with a new one could save you money in the long run.

Overall, the decision to replace your hot water system should be based on factors such as age, performance issues, energy efficiency concerns and recurring maintenance expenses.

By considering these aspects carefully before making a decision about replacement will ensure that you have access to reliable and efficient hot water supply while also saving on costs in the long term.


One Key Consideration is the delivery

An electric hot water system is a type of storage tank that heats and stores hot water for use in homes.

Solar  systems generally provide about 10 years of piping hot water. If you have a continuous flow system, it can last up to an impressive 20 years. So, when choosing a new hot water system for your home, keep in mind the lifespan expectancy of different types and choose one that best suits your needs and budget.

Some top brands include Rheem, Everhot, Thermann, Stiebel Eltron, Aquamax, Vulcan. These offer affordable and efficient electric hot water systems with excellent energy efficiency ratings.


By using off-peak tariffs to operate your heater and insulating your storage systems properly, you can bring down your running costs drastically.

It's safer to call in a professional plumber when dealing with Electric Hot Water Systems as they know how to handle pipes and tubing along with other fixtures and fittings correctly.

No! While many people choose to have their heaters installed outdoors due to space constraints or safety concerns, they can also be set up indoors depending on the model chosen.

Yes! Depending on where in Australia you live like Brisbane, Gold Coast , Sydney or Melbourne; local government might offer rebates on high-efficiency models which helps reduce your cost.

Right Choice


In conclusion, electric hot water systems can be a great choice for Australian homes. They come in different types and sizes to suit your needs and are available at affordable prices. With their energy efficiency and potential rebates, they can help you save on your energy bills while providing reliable hot water.
