Choosing a hot water system?
Discover the Sanden "Eco®" Hot Water Heat Pump System.
How does the Sanden "Eco®" Hot Water Heat Pump System work?
The Sanden "Eco®" Hot Water Heat Pump System works in a different way compared to a conventional electric hot water system. The Sanden "Eco®" Hot Water Heat Pump System operates like a refrigerator in reverse. It contains a fan that forces air through an evaporator that contains a refrigerant. The heat in the air passes through the evaporator and is absorbed by a natural refrigerant, R744 (CO2), which is ozone friendly and does not contribute to global warming.
The warm gaseous refrigerant is circulated in the system via a compressor. As it passes through the compressor, its pressure rises, as does its temperature. This hot refrigerant then passes through a heat exchanger to heat the water, which is finally pumped to the storage tank.
Performance & Savings
The Sanden "Eco®" Hot Water Heat Pump System delivers:
- Industry leading energy efficiency - uses only 22% 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.
- Industry leading quality & performance, with the highest level of STC values of currently available hot water heat pumps.
- Class leading warranties, backed by Sanden’s 30 years of operation in Australia.
As the Sanden "Eco®" Hot Water Heat Pump System uses R744 (CO2) refrigerant technology, the amount of electrical energy required to heat the water is significantly less than that required by a conventional electric hot water system.
In fact, the Sanden "Eco®" Hot Water Heat Pump System consumes 1kW of electricity to generate 4.5 kW of heat (COP = 4.5*), which equates to 22% of the energy used by a conventional electric system. Consequently, with the Sanden "Eco" Hot Water Heat Pump System, you can save up to 78% of your conventional electric hot water energy costs!
Features & Benefits
The Sanden "Eco®" Hot Water Heat Pump System is supplied as two separate components;
- Heat Pump Unit and
- Stainless Steel Storage Tank.
This allows easy on-site handling and installation, as well as flexibility of the storage tank location, up to 4 metres distance from the Heat Pump Unit. The system is suitable for a family of 3-6 people.
