Sanden offers a breakthrough in water heating technology with the CO2 Hot Water Heat Pump System. The unique design offers an environmentally friendly water heating solution providing drastic energy savings and reductions in carbon emissions. A brilliant alternative to solar hot water systems.

The state-of-the-art heat pump is highly efficient and uses only around 22% of the energy consumption of conventional electric hot water systems. The heat pump offers environmental benefits with the use of a natural, CO2 refrigerant and reduced energy usage resulting in savings of as much as 3 tonnes of greenhouse gas emissions per year.

On-site installation is made easy with the unique split design having two modules, the Sanden Heat Pump and the Edson Stainless Steel Storage Tank that can be located up to 4 metres apart.

The Sanden CO2 Hot Water Heat Pump System is eligible for 32 Small-scale Technology Certificates (STCs) in zone 3 (including the ACT).
