When looking for an energy-efficient hot water solution, an air-sourced hot water heat pump system offers an excellent option. These systems extract heat from the surrounding air and use this energy to heat water, making them a smart choice for eco-conscious homeowners. Although powered by electricity, heat pumps are significantly more efficient than traditional electric water heaters, offering approximately three times the efficiency. This technology not only reduces energy consumption but also cuts your energy bills and minimises greenhouse gas emissions, contributing to a healthier planet.
One of the standout options is the Sanden Eco Plus system, featuring a smart split system design. Unlike other heat pumps, the Sanden model installs the heat pump unit separately from the durable stainless steel tank. This flexibility in installation simplifies handling on-site and allows the storage tank to be positioned up to 15 metres horizontally or 5 metres vertically away from the heat pump unit. This adaptable design makes the Sanden system ideal for various site layouts, improving installation efficiency.

You can save up to 80% of your conventional electric hot water energy costs! The Sanden Eco® Plus Hot Water Heat Pump uses only 20% of the energy required by an electric storage hot water system.
Not only does a Sanden Eco® Plus Hot Water Heat Pump help save on energy costs, it also delivers:
(a) The Heat Pump Unit
(b) The Stainless Steel Storage Tank
The Sanden Eco® Plus Hot Water Heat Pump operates like a refrigerator in reverse. It contains a fan that forces air through an evaporator that contains a refrigerant. The heat in the air passes through the evaporator and is absorbed by a natural refrigerant, R744 (CO2), which is ozone friendly and does not contribute to global warming.
The warm gaseous refrigerant is circulated in the system via a compressor. As it passes through the compressor, its pressure rises, as does its temperature. This hot refrigerant then passes through a heat exchanger to heat the water, which is finally pumped to the storage tank.
Sanden has 4 hot water systems to choose from, model numbers GAUS-315FQS has a tank size of 315L, model number GAUS-300FQS has a tank size of 300L, model number GAUS-250FQS has a tank size of 250L and model GAUS-160FQS has a tank size of 160L. The Sanden Eco® Plus Heat Pump unit is the same for each system. Which one you choose depends on the space requirements of the location where you are installing it. Please speak to your local Sanden Dealer/Installer about making the best choice for your location.
Yes, but CO2 has a Global Warming Potential (GWP – see below for explanation) of 1. Carbon dioxide is the baseline measurement of how it will contribute to global warming for a given mass.
Our system utilizes less than 1 kg of R744 (CO2) as a refrigerant contained in a closed system at the factory. The installer does not need to charge the heat pump on site.
Global warming potential (GWP) is a measure of how much a given mass of greenhouse gas is estimated to contribute to global warming. It is a relative scale which compares the gas in question to that of the same mass of carbon dioxide (whose GWP is by convention equal to 1). A GWP is calculated over a specific time interval and this time interval must be stated whenever a GWP is quoted or else the value is meaningless.
The unit is rated at 37dB (measured at 1 metre distance from the unit), which is almost silent. By comparison, a whisper is around 30dB and inside a library is approximately 40dB.

The Sanden HWHP will operate effectively between minus 10 and plus 43 degrees C, without the need for an electric backup/booster element. It is also fitted with in built freeze protection, making it suitable for all climates. Please note that in cold climate regions, the Heat Pump unit will run during the night when the ambient temperature drops below 3 degrees C. If used in an Off-Grid system, please ensure that adequate power is available.
No, unlike other competitor HWHP systems, the Sanden Eco® HWHP system does not require an electric booster element.
Yes, please refer to the Installation Manual for details. There are no special settings for off peak connection. Simply ensure that the off peak tariff supplies a minimum of 5 hours continuous power to the Sanden HWHP.
The purchase and installation of a Sanden Eco® Plus Hot Water Heat Pump entitles you to Small-scale Technology Certificates (STCs) – formerly known as Renewable Energy Certificates (RECs). For more information: visit www.environment.gov.au/climate-change and www.cleanenergyregulator.gov.au
The Sanden HWHP achieves the highest level of STCs of any hot water heat pump, currently available in Australia.
Yes. Importantly, no warranty applies to the heat pump unit and the storage tank, where the chloride level exceeds 200 mg/litre and the pH is less than 6.0 or more than 8.5. If in doubt, it is recommended that water chemistry information be sought from your local council or water supplier. Please refer to the separate section on Water Quality here.
Please contact the Sanden Dealer/Installer from whom you purchased your unit. If you are unable to reach your Dealer/Installer, then please call Sanden on (02) 97910999 OR Freecall 1800 146 123.

The Sanden Eco Plus heat pump boasts a high Coefficient of Performance (COP=5^), significantly lowering energy consumption and CO2 emissions. It offers up to 50% faster heat recovery than standard systems, uses the eco-friendly R744 (CO2) refrigerant, and can be easily installed by a plumber and electrician—no specialised refrigeration mechanic required.
Designed for compatibility with solar electricity systems, it operates automatically to complement power generated from rooftop photovoltaic panels. The unit performs efficiently in a wide range of climates, operating between -10°C and +43°C, and remains effective in cooler regions, even when temperatures dip below 3°C.
Enhancing convenience, the system includes a blockout timer to avoid periods of high electricity tariffs, and it operates with a whisper-quiet noise level of just 37dB, ensuring it won't disturb your home or neighbours. Constructed from high-quality, weather-resistant materials and available in four tank sizes (160L, 250L, 300L, and 315L), each tank is made from Australian marine-grade 316 stainless steel for durability and corrosion resistance.
