Enhanced Performance and Savings with Sanden
Sanden stands out in the Australian market as the only hot water heat pump (HWHP) provider using environmentally friendly R744 (CO2) refrigerant. This superior refrigerant technology significantly reduces the amount of electrical energy needed to heat water compared to traditional electric storage hot water systems.
The Sanden Eco® Plus Hot Water Heat Pump System is exceptionally efficient, consuming just 0.84kW of electricity to produce 4.99 kW of heat, which translates to a Coefficient of Performance (COP) of 5.96. This efficiency means it uses less than 20% of the energy of a conventional electric storage system. As a result, the Sanden Eco® Hot Water Heat Pump System can help you achieve up to 80% savings on your hot water energy costs related to conventional electric storage systems, making it a smart choice for both your wallet and the environment.
Whisper Quiet Operation
Noise levels are a crucial consideration when selecting a hot water heat pump system. Sanden has conducted extensive research to develop a system that operates at a 'whisper quiet' noise level of 37dB. This ensures that the Sanden hot water heat pump system operates unobtrusively, preserving the tranquility of your home environment and maintaining good relations with neighbours.

F.A.Q
Frequently Asked Questions
-
Do I need to register my Sanden Eco Plus warranty?
Yes, for efficient processing of warranty claims, should they arise, please register your Sanden Eco® Plus heat pump hot water system here.
-
Is water quality an important consideration for the Sanden Eco® Plus heat pump hot water system?
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. If in doubt, seek water quality information from your local council or water supplier.
-
Does the Sanden Eco® heat pump hot water system require the assistance of an electric booster element to heat water, when outside ambient temperatures are very low?
No, unlike other competitor heat pump hot water (HPHW) systems, the Sanden Eco® HPHW system does not require an electric booster element
Advanced Design and Flexibility with Sanden Eco® Plus System
The Sanden Eco® Plus hot water heat pump system stands apart with its intelligent split system design, featuring a separately installed heat pump unit and stainless steel tank. This configuration allows for easier handling and installation on-site, plus flexible placement of the storage tank up to 15 meters horizontally or 3 meters vertically below the heat pump unit.
Heat Pump Unit Features:
High Efficiency: Boasts a high Coefficient of Performance (COP=5.96^), significantly reducing energy usage and CO2 emissions.
Rapid Heat Recovery: Achieves up to 50% faster recovery than typical heat pumps.
Eco-Friendly: Utilizes ozone-friendly R744 (CO2) refrigerant.
Easy Installation: Requires only a plumber and electrician for installation.
Automatic Heating Cycle: Ideal for integration with rooftop photovoltaic (PV) solar systems.
All-Climate Operation: Designed to function in a wide range of temperatures from -10°C to +43°C. Note: In cold climates, the unit operates overnight when temperatures drop below 3°C.
Blockout Timer: Avoids high electricity tariff periods.
No Backup Element Required: Streamlines operation and reduces costs.
Quiet Operation: Industry-leading low noise level at 37 dB.
Leading Warranty: 6-year warranty.
Why use the Eco-friendly R744 (CO2) refrigerant?
It offers no ozone layer depletion and minimal global warming (ie. as per table below) versus other commonly used refrigerants, should the system leak.
It performs higher compression efficiency, with lower energy consumption, thereby allowing more heat to be transferred to the water, for less energy used (i.e. excellent thermodynamic ability).
The refrigerant temperature gets very hot, very quickly, so water temperature of 63ºC, is achieved almost instantly from the Heat Pump unit.
Stainless Steel Tank Features:
Durable Material: Constructed from 316 Marine Grade stainless steel, with diameter of 621mm
Insulated: Fully insulated to minimize heat loss.
Pressure Rated: Mains pressure rated for safety and performance.
Safety Features: Includes a pressure and temperature relief valve.
Long-Term Warranty: 15-year Pro Rata Warranty covering parts and labour.
