Dux Australia Product Types

Dux Australia offers a wide range of products that cater to both domestic and commercial needs. Its core product offerings include electric hot water systems, gas systems, continuous flow, electric solar, gas solar, and heat pumps. More about the Dux hot water systems product range and best-selling products are detailed below.

Electric Hot Water Systems

An electric hot water system is a popular choice for many Australian households. The upfront costs of Electric hot water systems are significantly lower in comparison to other types of water heaters, such as tankless or solar heaters. 

This type of hot water system is also relatively easy to install. It’s a common choice for many households, as most homeowners are familiar with this type of water heater, so there’s no learning curve of how to maintain it (solar power systems are a little different but not so complex to operate).

People may choose not to go with electric hot water systems if they have a larger household and need a more hot water supply, as electric systems are limited by their tank size. In most cases, these systems are less energy-efficient than tankless or heat-pump water heaters. This can lead to higher operating costs due to continuous heating. Although, it’s important to note the exact costs depend on factors like electricity rates and usage.

Gas Hot Water Systems

A gas storage hot water system uses natural gas or propane to heat and store hot water in a storage tank that is well insulated. This type of system is able to produce a consistent supply of hot water, making it a great choice for households with moderate to high hot water usage. Gas is also often more cost-effective than electricity, leading to lower monthly bills.

These systems are able to reheat water quickly when the tank is empty. This means you can have multiple uses in a short amount of time. Despite being able to quickly reheat water, the tank size will determine the amount of hot water your household will have access to. They are less energy-efficient compared to tankless water heaters or heat pumps, leading to higher energy consumption (and therefore higher monthly bills).

Continuous Flow Hot Water Systems

As the name suggests, a continuous flow hot water system heats water continuously (as it is needed) rather than storing hot water in an insulated tank. They are also known as tankless or on-demand water heaters. Due to the continuous supply of hot water, you won’t need to worry about running out of hot water. 

As the continuous flow hot water systems only heat water when it is needed, they are often more cost-efficient in the long run in comparison to electric storage systems. The Dux continuous flow hot water systems also don’t have a large storage tank, so they’re much smaller and can, therefore, be installed in smaller spaces. Installation may require changes to gas lines or electrical wiring that may be quite different from your current hot water system, which can increase installation costs. These systems also often have a higher upfront cost than storage tank water heaters in the general hot water system market.

Heat Pump Systems

A heat pump water heating system uses electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy efficient than conventional hot water systems. Heat Pumps produce fewer greenhouse gas emissions compared to conventional systems like gas or electric.

These units are a great choice if you’re concerned about lowering your carbon footprint. As they are much more energy-efficient than conventional hot water systems, they also cost considerably less money to run.

These systems require a larger investment to purchase and install compared to conventional electric hot water systems, and heat pumps generally need a considerable amount of space for proper installation and proper ventilation.

Electric Solar Hot Water System

An electric solar water heating system uses the sun’s energy to heat water. Solar water heating is environmentally friendly, as it produces fewer carbon emissions and doesn’t require the use of fossil fuels. Electric Solar hot water systems systems can significantly reduce electricity or gas bills, especially in sunny regions, leading to lower monthly bills.

In fact, homeowners can save up to 50-80% on their water heating bills with this type of system. Payback periods vary but are typically around 4 to 8 years. Solar water heaters have a much longer lifespan than conventional water heaters, often lasting up to 20 years. As these systems are dependent on sunlight, they are not as efficient on cloudy or rainy days. 

When there isn’t enough sunshine to fully heat the water, a gas or electric booster will kick in as a backup. Your home will need sufficient roof space and sun exposure for solar panels, which can be challenging for some homes. 

Gas Solar Hot Water System

A gas solar hot water system is a hybrid system that combines a solar system with a gas backup or booster system. These systems are super energy-efficient because they harness free solar energy. This not only reduces your gas consumption but also trims down your monthly utility bills. Gas solar systems cut down on greenhouse gas emissions that come hand-in-hand with gas-only systems.

Thanks to the backup gas component, you’ll have a steady supply of hot water even on cloudy days or periods of high usage. You’ll need adequate roof space for your solar panels or a dedicated sunny spot on your property to install a gas solar system. In order to keep the system functioning optimally, it needs regular maintenance. This includes cleaning your solar panels and checking for leaks.
