STIEBEL ELTRON 303 LITRE HEAT PUMP

The Stiebel Eltron Heat Pump is proven superior German technology and is the most efficient domestic heat pump on the market.

It works on similar principles as an air-conditioner but in reverse. 68% less electricity is required to provide hot water compared to a standard electric system.

The heat pump is also much cheaper to install than a solar hot water system. The use of a heat pump alone is generally enough to reduce your domestic hot water costs by about 68% compared with a conventional electric storage hot water system. With its 303 litre tank the Stiebel Eltron Heat Pump delivers in excess of 500 litres of domestic hot water.

How is water heated?

Air which contains solar heat energy is extracted by the Heat Pump to heat water. A fan draws air through an evaporator which contains very cold liquid refrigerant. The heat in this air is absorbed by the refrigerant, turning it into a very hot liquid. The hot liquid refrigerant is then compressed to a "super heated" gas via a compressor. The gas is then circulated to a condenser, where the heat from the gas is transferred to the water in the tank. The now cool refrigerant is then reused and the cycle starts all over again. Power is only required to operate the compressor to move the heat around the system, not to heat the water.

Does the unit draw much power?

No, it has the lowest current draw of any Heat Pump on the market, 2.17amps or 520watts. This is significantly lower than a standard electric hot water system which uses 3600watts.

To what temperature will the unit heat the water?

By law, all storage hot water heating apparatus must heat water to a minimum 60°C. This unit is more efficient because the water is not overheated.

How much hot water will I get from the unit?

Due to its advanced German design features, you will get approximately 540 litres of shower temperature water* from one tank which is plenty of water for 2-5 people.

*Shower temperature water is 60°C water and cold water mixing to give you approximately 40°C water.

What rebates are available?

The Stiebel Eltron Heat Pump is eligible for the Federal Government Small-scale Technology Certificates (STCs) discount.

Warranty Information

The Stiebel Eltron Heat Pump has a five year warranty on the tank, two years on the compressor and one year on the electrics.

The unit has a design life of fifteen years. This can vary depending on factors such as extremes in weather, water quality and how often you replace the sacrificial anode. We recommend replacing the anode every 3-5 years for continued protection, depending on the water quality in your area.
