Sanden Eco Plus Heat Pump
The Sanden Eco Plus Heat Pump Hot Water System is a premium hot water solution designed for Australian households seeking efficiency, sustainability, and long-term savings. With advanced technology out of Japan, the Sanden is famous all over the globe for taking delight in producing the most silent, highly energy-efficient hot water systems that stand the test of time. CO₂ refrigerant in the Eco Plus model means unparalleled energy efficiency and hence one of the cleanest options to choose from.
At home with a stainless-steel tank, whisper-quiet operation, and long life, the Sanden Eco Plus is an excellent choice for families who need reliable hot water, less electricity bills, and a smaller carbon footprint.
How the Sanden Eco Plus Works
- A fan draws in ambient air and transfers heat to the natural CO₂ refrigerant.
- The refrigerant is compressed to generate high temperatures.
- This heat is transferred to the water stored in the stainless-steel tank.
- The cycle continues until the water reaches the desired temperature, then pauses to save energy.
- The system restarts only when water temperature drops, ensuring constant supply.
This advanced CO₂ heat pump technology allows Sanden to deliver reliable hot water even in cold Australian winters, making it one of the best-performing systems on the market.
