Sanden Hot Water

Why consider an Air-Sourced Hot Water Heat Pump System?

An air-sourced heat pump absorbs heat from the air and transfers it to heat water. It runs on electricity but is roughly three times more efficient than a conventional electric water heater. It is designed to save energy and money and reduce greenhouse gas emissions.


Superior features and benefits of Sanden Heat Pumps

Unlike other hot water pump systems, the Sanden Eco Plus system uses a smarter split system where the heat pump unit and stainless steel tank are installed separately. This allows easy on-site handling and installation, as well as flexibility of the storage tank location, which can be up to 15 metres distance horizontally or 5 metres vertically from the heat pump unit.

– Heat Pump Unit

– A high Coefficient of Performance (COP=5^) results in significantly reduced energy use and CO2 emissions.

– Up to 50% faster heat recovery than typical heat pumps.

– Uses unique Ozone friendly R744 (CO2) refrigerant.

– Simple installation by Plumber & Electrician, with no Refrigeration Mechanic required.

– An automatic heating cycle, which makes it perfect for use with power generated by on roof photo voltaic (PV) solar electricity systems.

– Uniquely designed to operate in all climates (ie.-10C to +43C operating range). NOTE: In cold climate regions, the Heat Pump unit will run during the night, when the ambient temperature drops below 3C. If used in an Off Grid system, please ensure that adequate power is available.

Includes Blockout Timer, to eliminate high electricity tariff periods.

– No backup element required.

– Whisper quiet operation, which industry leading noise level of 37dB- very neighbour friendly!.

– High quality, Japanese made weather resistant construction for outdoor location.

– 6 year Warranty (including parts and labour)

Stainless Steel Tank. 

– 4x tank sizes offered –160L, 250L, 300L and 315L

– High quality, Australian made extra long life 316 Marine Grade stainless steel cylinder.

– Fully insulated for minimal heat loss.

– Mains pressure rated.

– Safety pressure and temperature relief valve supplied.

– 15 year Pro Rata Warranty (including parts and labour)

 How Sanden delivers better Performance and Savings.

Sanden employs superior R744 (CO2) refrigerant   technology, so that the amount of electrical energy required to heat the water is significantly less than that required by a conventional electric storage hot water system. In fact, the Sanden Eco Plus Hot Water Heat Pump System consumes 1kW of electricity to generate a 4.5kW of heat (COP=5^) which equates to 20% of the energy used by a conventional electric storage system. Consequently, with the Sanden Eco Hot Water Heat Pump System, you can save up to 80% of your conventional electric storage hot water energy costs!

Every Sanden Eco Plus Hot Water Heat Pump System is fully backed by our extended warranties. Sanden Eco Plus Hot Water Heat Pump units feature a 6-year class leading warranty, while the stainless steel storage tank also has a class leading 15-year warranty, providing you with peace of mind. For full warranty conditions, please refer to The Sanden warranty applies alongside, and in addition to, any rights or remedies to which you may be entitled under the Australian Consumer Law.

Did you know that Heat Pump technology is more energy efficient than Solar?

During the period 2009-2013, the Campbell Creek Energy Efficient Project compared the energy usage of three homes, each with different types of water heaters.

Test results for the period January to December 2012, confirmed that the Solar Flat Panel system used 38% more energy than the Hot Water Heat Pump.


Is Sanden quiet?

When purchasing a hot water heat pump system, noise levels are an important consideration.

Sanden’s extensive research has delivered a ‘whisper quiet’ operating noise level (37dB) that ensures both you and your neighbours’ lifestyles remain unaffected by its operation.

Enjoy the higher STC rewards even before you turn a hot water tap on

The new Sanden Eco Plus system is the most energy efficiency hot water pump currently available on the market. As such, when you buy a Sanden system, you receive the highest amount of Small-scale Technology Certificates (STCs) of any currently available hot water heat pump system. These STCs can be used to discount your purchase price. For more information, ask your local Sanden Dealer or visit or

How a Sanden Eco Plus System Works.

The Sanden Eco Plus Hot Water Heat Pump System uses a small amount of energy to move heat from one location to another. Heat is absorbed by ozone-friendly R744 (CO2) a natural refrigerant which does not contribute to global warning. As the warm gaseous refrigerant circulates through the compressor, and its pressure and temperature rises. The hot refrigerant then passes through a heat exchanger which heats the water. The refrigerant is cycled back into the system, and hot water is pumped to the storage tank.
