Types Of Water Heaters

There are various types of hot water heating systems available in the market. Depending on your needs, you might prefer a kind of heater compared to others. To help you decide which sort of water heating system is most suitable for you, we’ve listed some of them:

Gas Storage Hot Water Systems

Gas Hot Water System

Gas Hot Water System gets heated by gas. This type of water heater is very common throughout most parts of the east coast, where natural gas is piped to many houses and suburbs. One of the best things about gas water heaters is their recovery time, gas water heaters will replenish the heat back into the water faster than a traditional electric unit. Gas hot water tanks can be installed both inside and out, however, there are fewer options internally and really as professionals we believe installing gas water heaters outside is far more advisable. Always ensure when using a heater like this that it has been installed by a professional as gas can be dangerous if not handled correctly.
Electric Hot Water System

Electric Hot Water System

An Electric Water Heater is the most common water heater in Australia  and obviously needs electricity for it to work. There are several tricks to ensure that these units run economically for you, so be sure to contact a professional when installing or think of installing an electric water heater as you really need to buy the unit that suits your needs. Despite that, this hot water system has some great things about it. It does not make any noise and are marginally safer to use than gas. Installing heaters like this can be done inside the house, and run in conjunction with solar power these  heaters really come into their own.
Solar Hot Water Systems

Solar Hot Water System

But, if you plan on investing in a high-quality water heater that can last you for years, then this is your best choice, and more often than not a solar water heater will pay for itself within a matter of years.

Heat Pump Hot Water System

Heat Pump Hot Water systems are also environmentally friendly. However, unlike solar water heaters, they still require electricity. But, heat pump water heaters require less energy than electric hot water systems by about half. The disadvantage of buying a heater like this is that they are slower to recover and does make some noise however it isn’t offensive, similar to that of an air conditioner. These water heaters are ideal for using with solar power to reduce your consumption even further.

Energy Consumption

If you know where your water heater gets its energy to work i.e. gas, or electricity, you also will be able to predict how much you have to spend running your heater. So, if you prefer to spend a large amount of money to buy a quality heater, you get to spend less on energy consumption. And, vice versa.


The capacity of the hot water system you need depends on your hot water consumption, for example, you may have a spa bath that you use regularly or 5 teenagers, if this is the case then a larger faster recovery unit is what you need, however, if you only have a small two bedroom house with 1 person using the hot water then you likely only need a small capacity unit.


Before purchasing a hot water heating system, you have to consider the space where you will be installing your heater. Why? Because the model you will buy might not fit in the allocated space for the unit. Also, you need to look into the installation instructions for the water heater. It will let you know whether you have to install it outside or inside the house.


Now that we know the factors that determine a great water system, we also have to know the best water heaters in the market. To help you with this, we curated this list of the best water heaters. So let’s get to it:
