The Sanden Heat Pump works in a different way compared to a conventional electric hot water system, it’s 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 the global warming.

The warm gas 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 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 hot water Heat Pump System uses (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 Heat Pump consumes 1kW of electricity to generate 4.5 kW of heat which equates to 22% of the energy used by a conventional electric system. Consequently, with this system you could save up to 78% of your conventional electric hot water energy costs!
