Built to last in Australian conditions.
Heat pumps designed in Australia by Wilson Industries. Wilson is an innovative Australian business that’s been manufacturing hot water systems for more than 90 years.
Getting the job done for more than 90 years.
Wilson Hot Water has been making domestic hot water tanks for over 90 years varying from copper to bespoke stainless steel. We’ve applied the wealth of knowledge we’ve acquired to design and develop an energy efficient heat pump hot water heater.
Using R290, an environmentally friendly refrigerant, the Wilson heat pump can deliver temperatures of 70°C and offer home owner’s significant savings on energy costs.
*The Unit is registered for STC rebates with an outlet temperature of 63°C – any changes to temperature will void any STC claims.

Future-proof your home against rising energy costs

The Wilson Aqualux Heat Pump hot water systems have been meticulously designed to minimise energy consumption whilst maximising the hot water available in the stainless steel storage tank.
Our revolutionary use of inverter technology controls the refrigerant compressor – a variable speed fan motor which allows the fan to run at different speeds according to the system needs. This technology increases efficiency and minimises noise levels.
Take advantage and save up to 78% of your hot water energy costs
The Wilson Aqualux Heat Pump consumes 78% less energy than typical resistance hot water heaters. The energy consumed is used to drive the refrigerant system to generate heat. The Aqualux Heat Pump uses significantly less energy than the typical resistance heater – which operates in a similar way to your electric kettle.
Innovative heat pump technology proves more efficient than solar
The Wilson Aqualux Heat Pump works seamlessly with your photovoltaic (PV) system designed to run when PV output is maximised. If you don’t have a PV system times can be accessed via the controller or WI-FI controller to match your energy providers off peak tariff times.
Aqualux uses 78% less energy than traditional water heaters
The Wilson Aqualux Heat Pump hot water system uses up to 78% less energy than a conventional resistive hot water heater.
Tested to AS 2515 the COP of the Aqualux system is 4.52, which means for each 1 Kw of power consumed the Aqualux system generates 4.52 Kw of heating. By comparison, a typical resistive system generates just 1 Kw of heating per Kw of energy.
Heat pump technology is more efficient than other forms of hot water heating
Sustainability Victoria has concluded that “these systems typically use around 60% to 70% less electricity than a conventional electric hot water system. This is because the electricity is used to operate the heat pump and doesn’t heat the water directly with an element.”
The Aqualux heat pump has a specifically designed storage tank which stratifies the water in the tank, effectively heating the water from the top down so the delivery of water is quicker. Conventional systems heats the water from the bottom up in a mushroom effect, which requires the whole tank to be heated before hot water can be drawn off.
See how your choice of heating technology can impact your hot water energy consumption and costs from the chart below.
4 Person Home – Energy Costs By Heating Technology

Sustainability Victoria compared the costs of various heating technologies and concluded that running costs for heat pumps are significantly lower and greenhouse emissions are considerably lower than any other form of hot water heating technologies. These calculations should be used as a guide only. Your water heating energy costs will depend on:
- the number of people in your household
- how you use hot water
- your energy tariffs
- your climate
- how efficient the system is
- the length and insulation of connecting pipes
- the flow rates (water efficiency) of taps and showers.

Federal and State Rebates
Rebates and financial incentives are offered Australia-wide at a federal and state level for using hot water heaters powered by renewable energy. Additional rebates may be available from state governments or local councils.
What are Solar Hot Water Rebates?

Replace your old resistive hot water system to an energy efficient Wilson Aqualux Heat Pump Hot Water System and you may be eligible for various Federal and state Government solar hot water rebate. Rebates are financial incentives created to encourage investment in renewable energy. The number of STC you are entitled to varies depending on the climate zone you live in (refer map)
Talk to your authorised installer who can provide estimates on the rebates and incentives you are eligible for. Your dealer will also provide you with pathways on claiming your various incentives and rebates.
Small-scale Technology Certificates (STCs)
STCs are rebates available nationally that can offset the initial cost of your CO2 Heat Pump Hot Water System. An STC is a measure of renewable energy that can be traded for cash, or a discount, on the purchase price of a hot water system. Each STC represents a megawatt hour (MWh) per year of electricity displaced by an eligible system. For more information on STCs go to the Clean Energy Regulator website
Victorian Energy Efficiency Certificates (VEECs)
In Victoria only, set by the Victorian Energy Upgrades (VEU) program, VEECs are available as rebates, where a VEEC is awarded for installing a heat pump to replace less efficient electric water heater. For more information on VEECs, go to the VEU website
Solar Victoria provides rebates on eligible heat pump hot water systems. For more information go to the Solar Victoria website
ESS Rebates (NSW)
How Scheme works
energy savings equipment and appliances in NSW households and businesses. Financial incentives are in the form of tradeable certificates, called energy savings certificates (ESCs). For more information on ESCs, go to the ESS website

A Heat Pump is different to a solar collector. Heat pumps use the air to extract heat and are mounted on the ground. Solar collectors need the sun to collect heat and are mounted on the roof.
A heat pump can replace an electric water heater within a day, quicker if the electrical supply is located close by to the heat pump.
Any hot water heater or heat pump needs to be installed by a qualified tradesperson, ensuring it is installed to all the correct Australia Standards.
The Aqualux Heat Pump has full WiFi connectivity and can be operated from your mobile phone.
The control logic of the heat pump does not collect personally identifiable information but collects performance data from the serial number. It will provide troubleshooting information if your unit has a fault, potentially minimising service repair costs.
Yes – there are rebates available; please refer to the rebate calculator for your area.
Yes they do – typically heat pumps operate at approx. 30% of the energy use when compared to a standard electric water heater
