It’s time to take a look at the top 5 hot water systems in Australia. For this list, we will review two electric heaters, two gas water heaters, and one solar hot water system and let you know what we think are the best options for people living in Adelaide.

1. EvoHeat EVO270

Electric hot water system

The EvoHeat EVO270 provides hot water up to 60°C. The brand claims that EvoHeat’s heating technology, which uses only 1kW of energy to generate 3.4kW of heat, can save up to 75% on hot water costs. This might be why the EVO270 is also registered with the Australian Federal Government Clean Energy Regulator as an energy-efficient water heater.

It has a 270L storage capacity, suitable for supplying enough hot water for your entire family. It also features a Hydro Power Boost function that provides a constant stream of hot water, a built-in timer to take advantage of off-peak energy periods, and a Vacation Mode to reduce energy usage while you’re away from home.

Best features

• Quick operation
• Constant hot temperatures
• Easy-to-read display panel
• Energy-saving features such as the timer and vacation mode

2. Joolca HOTTAP

Gas hot water kit

For those with an adventurous spirit who would still like the comfort of having a hot shower even in the wild, this is your best friend. HOTTAP comes in different versions, all of which are portable hot water systems that you can take anywhere.

Being outdoorsy will never be the same. Connect your HOTTAP with snap-on fittings for gas and water, and that’s it. Plus, it comes with a two-stage water filter that removes any sediments, making it sturdy enough for rivers and creeks. Its robust IP3X-rated pump can also resist rain, sun, hail, and more.

Best features

• Brass quick connection for gas
• Over 15 hours run time on a single gas tank
• Internal microprocessor prevents water temperature from exceeding 50°C, ensuring safety for kids and pets

3. Hydrotherm

Electric hot water system

This one is pretty spot on! It works similarly to your fridge or air conditioning unit but in reverse, transferring heat from ambient air into the refrigerant and finally into the water inside the tank. With a 6-year warranty, Hydrotherm is built specifically to withstand Australian conditions, so you can expect it to last 10-15 years.

Another plus of this hot water system is its 350% efficiency rating, which significantly reduces running costs compared to gas and electric water heaters.

Best features

• Registered Clean Energy product with an annual carbon reduction rating of 3 tonnes
• Dual heating technology with incorporated electric elements providing hot water up to 70°C
• R290 natural refrigerant with effectively zero global warming potential compared to synthetic refrigerants

4. Dux Prodigy 4

Gas hot water system

The Dux Prodigy 4 offers an energy efficiency rating of 4.2 stars or higher, depending on usage. Plus, you don’t need a power point to get hot water, so even during a power outage, you can still enjoy a warm shower.

It features new burner technology that delivers faster recovery rates. You can get the Dux Prodigy 4 with a 135L (suitable for 3 to 6 people) or a 170L capacity (suitable for 4 to 7 people), both available in natural gas and propane. The tank comes with a 7-year warranty, and parts and labor have a 1-year warranty.

Best features

• Reliable, steady, and strong hot water flow
• Easy and quick installation
• Energy-efficient

5. iStore Air to Energy

Solar hot water system

The surprise water heater on this list and the ruler of the 5th position is the solar hot water system, iStore Air to Energy.

iStore presents air-to-energy technology that creates heat from compression. This makes it energy-efficient, reducing carbon emissions by up to 4 tonnes, and pocket-friendly. It is compatible with a PV solar power system, which is great, considering that it’s estimated that when used with solar power, energy costs can be as little as 11 cents daily.

It also comes with two in-built timers that you can customize to program the system for off-peak heating and save some extra money. Plus, its four intelligent operating modes are adaptable, including a hybrid mode for those days with family or friends visiting and a vacation mode.

Best features

• Great customer service, offering advice for installation and follow-up
• Hot water never runs out, even with 5 people in the house
• System temperature remains consistently high, not running out of hot water or becoming colder over time
