If you need to replace an existing electric hot water storage system, there's a lot to like about the Dux Proflo. Available in a variety of sizes to suit the hot water needs of different households, the Proflo can be installed inside or out and comes with a 10-year tank warranty on most models in the range.
It's no stranger to positive reviews either, with an average score of 4.1/5 from over 400 customer ratings on productreview.com.au. With all these factors taken into account, the Dux Proflo takes the win here as the best electric hot water system for Aussie homes.
Available in 9 tank sizes ranging from 25 litres through to 400 litres, the Proflo is suitable for use in a wide variety of households. The 25-litre and 50-litre versions come with 7-year tank warranties, while all other sizes come with a 10-year tank warranty and 1-year parts and labour warranty.
Delivering full mains pressure, the Proflo can be installed indoors or out depending on your needs. Water connections on both sides of the tank ensure easy installation, and the larger models (80 litres to 400 litres) feature a rust-proof polymer base along with 50mm thick foam insulation.
And while the 25- and 50-litre models are made in a Noritz manufacturing facility, all other models in the Dux Proflo range are made right here in Australia. So if you're searching for a practical and versatile electric hot water system, the Dux Proflo is well worth a closer look.
Searching for the best gas water system for your home? We recommend checking out the Dux Prodigy 4. An energy-efficient performer, this gas hot water system is easy to install and is made right here in Australia.
The Prodigy 4 has also come in for its fair share of praise from Aussie consumers, with an impressive average score of 4.4/5 from over 120 customer ratings on productreview.com.au. As a result, it's our top pick as the best gas hot water system.
The Dux Prodigy 4 comes in 2 sizes – 135 litres and 170 litres. The 135L model is designed for households with 3-6 people and has an Energy Rating of 4.5 stars, while the 170L model suits 4-7 people and has an Energy Rating of 4.2 stars. There's also a Dux Prodigy 5 available that offers better energy efficiency, but it has much lower customer review scores than the Prodigy 4.
Available in both natural gas and LPG models, the Prodigy 4 features dual anodes for a longer tank life and delivers mains pressure hot water to your home. It doesn't require a power point, which means you'll still get hot water even if there's a power outage, and operates on a standard size gas line.
The Dux Prodigy 4 is backed by a 7-year tank warranty and a 1-year parts and labour warranty, and choosing this gas system also gives you the peace of mind that comes with buying an Australian-made product.
As you can see from some of the other products already featured above, there's no shortage of highly rated heat pump hot water systems out there. Another heat pump system that's well worth a look is the Hydrotherm Dynamic/X8.
This system has a 350% efficiency rating, can provide enough hot water to suit 3-6 people and is backed by a 6-year warranty. These features and its performance have seen the Hydrotherm Dynamic/X8 receive ample praise from Aussie consumers too, with this system boasting an average score of 4.8/5 from over 40 ratings on productreview.com.au. As a result, it takes the win as the best heat pump hot water system.
With a 260-litre tank capacity, the Hydrotherm system can heat water to up to 70°C and suits homes of up to 6 people. It can make a big difference to your annual energy bill, and can reduce your annual carbon production by 3 tonnes.
This system is also registered as an energy-efficient solar water heater with the Australian Government's Clean Energy Regulator, which means it's eligible for a rebate in the form of small-scale technology certificates. Hydrotherm offers these certificates as an upfront discount off the price of your hot water system, but the size of the discount varies depending on where you live.
Another big selling point of this system is that it's backed by a 6-year warranty. This includes cover for the tank and all parts and labour, providing added peace of mind for buyers and making the Hydrotherm Dynamic/X8 well worth a look if you're searching for the best heat pump hot water system.
If you're in the market for a tankless hot water system, we recommend checking out the Dux Always Hot Condensing Continuous Flow system. This compact and practical unit is energy efficient, delivers hot water as needed, and comes with a long warranty on the heat exchanger.
These features have seen the Dux Always Hot Continuous Flow system win over Aussie consumers, with the Dux boasting an average score of 4.3/5 from over 45 ratings on productreview.com.au. And that's why it's our number-one pick as the best tankless hot water system.
The basic premise of a tankless system is that it only heats water as required, rather than the less efficient approach of storing hot water in a tank. As a result, the Condensing Continuous Flow model has an Energy Rating of 6.7 stars, while there's also a Non-Condensing model with a 6.1-star efficiency rating.
The more energy-efficient Condensing models come in 21L/min and 26L/min capacities, both of which feature a dual heat exchanger design that captures excess heat to improve efficiency. This means that you should never run out of hot water, while the fact that these systems use electronic ignition means that there's no standby pilot light.
Natural gas and LPG models are available, while the heat exchanger is covered by a 12-year warranty that includes 3 years of cover for parts and labour. So if you think a tankless hot water system will be the best choice for your home, there are lots of good reasons why the Dux Always Hot Condensing Continuous Flow could be the perfect solution.
If you're the type of person who prefers to have all the creature comforts when camping, a portable hot water system is a must. And if you're shopping for a camping hot water system, there are plenty of good reasons why you should check out the Joolca HOTTAP V2.
This portable unit gives you hot water anywhere you can take a gas bottle. It's easy to use, can be handheld or mounted, and boasts a stack of useful features. The HOTTAP V1 has picked up a lot of positive ratings on productreview.com.au, and V2 has an average score of 4.7/5 from over 75 Google reviews.

At the top of the range is the Nomad Kit ($599), which is ideal for those who like going well and truly off-grid. It has all the same inclusions as the Outing Kit but also adds items like a sink, 2 drying rack lids, a faucet head and handle, and extra plumbing equipment.
Whichever kit you choose, the HOTTAP V2 features a 27,000BTU burner, a flow of up to 6L/minute, one-touch operation and a handy LED display. So regardless of whether you're camping close to civilisation or way off the beaten track, the Joolca HOTTAP V2 will soon be the first item you pack every time you hit the road.
iStore Air to Energy is our choice as the best solar hot water system for a number of reasons. Not only is it highly rated by consumers on productreview.com.au, with an average rating of 4.9/5 from 26 customer ratings, but it also acts as a battery alternative and allows you to tap into your existing solar system.
Available in 180L and 270L models, the iStore can provide energy savings of more than 70% compared to electric storage. It works by taking excess energy from your home solar system and converting it into hot water using compressor technology. Instead of being sent back to the grid or to battery storage, the solar energy your system generates is put to use at home.
The iStore runs at 400% efficiency, and the company reports that when paired with Solar Roof Solar Power, its system can lower your water heating costs to as little as 11 cents per day. It can also reduce your carbon footprint, lowering the carbon emissions from your home by as much as 4 tonnes per year.
The 180L model is recommended for "water-conscious" households of up to 4 people, with the 270L version suited for homes with 5 or more residents. The iStore also offers 4 operating modes to suit different needs, including a hybrid mode for when you've got extra guests staying at your place for a short period.
Government incentives and rebates are also available if you replace your existing hot water system with an iStore Air to Energy, so check what sort of financial rewards are available where you live when deciding if this is the right hot water solution for your home.
If you're searching for the best hot water system to provide reliable hot water all year round, it's hard to go past the EvoHeat EVO270. This heat pump hot water system can reduce your hot water costs by up to 75%, is simple to use and offers easy installation.
It's also picked up a stack of glowing reviews from Aussie buyers, with an average rating of 4.8/5 from over 400 reviews on productreview.com.au. As a result, the EvoHeat EVO270 is our top pick as the best overall hot water system.
Designed for domestic and commercial use, the EVO270 uses 1kW of energy to generate 4kW of heat. In a domestic setting, it can supply enough hot water for up to 6 people, and with its Hydro Power Boost function can produce up to 105 litres of hot water per hour.
Control of the system is handled by an intelligent touchpad and a built-in timer. This allows you to choose when the unit operates so that you can use the energy generated by your home solar system or take advantage of off-peak tariffs. For even better energy efficiency, there's also a vacation mode that minimises any unnecessary heating while you're away from home.
Of course, one of the other major benefits of a heat pump system is that you may be entitled to government rebates in the form of small-scale technology certificates. The EvoHeat EVO270 is registered with the Federal Government's Clean Energy Regulator as an energy-efficient hot water system, so check out what sort of financial incentives are available where you live before you buy.
