#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 warming.
As the warm gaseous refrigerant circulates through the system it passes 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.
Why purchase a Sanden Eco® Plus Hot Water Heat Pump System?
✓ The superior design of a Sanden Eco® Plus Hot Water Heat Pump ensures:
✓ Industry leading energy efficiency using only 20% of the energy required by an electric storage hot water system.
✓ Innovative technology - up to 50% faster heat recovery than currently available Hot Water Heat Pumps.
✓ Perfect to use with Off-Peak Electricity for even more savings.
✓ The most STC rewards for energy efficiency, means you enjoy a greater discount on the purchase price.
✓ Class leading warranties, backed by Sanden’s 35 years of operation in Australia.
✓ Split system for ease of installation and near silent operation.
Superior Features and Benefits
Unlike other hot water heat 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 to15 metres distance horizontally or 5 metres vertically from the heat pump unit.
# Heat Pump Unit
✓ A high Coefficient of Performance (COP=4.5^) 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
