HOT WATER STORAGE UNITHEAT PUMP UNIT

How it WorksA heat pump is a device that uses a small amount of energy to move heat from one location to another.

The Sanden CO2 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, CO2 (R744) 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.

Greenhouse Gas Emissions FromHot Water Systems

Performance and SavingsThe end result of employing CO2  (R744) refrigerant technology is that 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 CO2 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 CO2 Hot Water Heat Pump System, you can save up to 78% of your conventional electric hot water energy costs!

Small-scale Technology Certificates (STCs) (formerly known as RECs)

The purchase and installation of a Sanden CO2 Hot Water Heat Pump System may entitle you to Small-scale Technology Certificates (STCs) if your system is eligible under the Small-scale Renewable Energy Scheme. STCs are sold and transferred to liable entities (usually electricity retailers) through a market based online system called the REC Registry, or via the ORER managed STC Clearing House.  For more information, visitwww.climatechange.gov.au www.rec-registry.gov.au
