    • Considerations
      Pros

      Flexibility with install for areas with tight spaces

      Environmentally Friendly – R744 refrigerant.

      Has a built-in block out system to enable the system to be used on

      Build in maintenance mode for easy servicing (by a licensed plumber).

      Light weight (when empty)

      Mains pressure hot water delivery.

      Cons

      Performance is slightly diminished in temperatures below 0oC

      Higher upfront costs

      Sufficient space is required around the Heat Pump unit.

      Hot water is not unlimited and will need time to recover if the tank is drained

    Thermann Split Heat Pump Owner's Guide

    Always use a licensed plumber when installing a hot water system.

    Combining a Japanese and Australian engineering, The Thermann Split Heat Pump is a flexible, quiet, and highly efficient hot water solution for any climate. By extracting heat from the air, this clever system uses a naturally occurring gas to heat water making it up to 80% more efficient than that of a standard electric storage system.

    • High efficiency
    • Flexible installation options for areas of limited space
    • Quiet operation (37dB)
    • Fast recovery rate
    • Government Rebates available (STC)
    • Block out mode for areas with on and off-peak tariffs as well as optimising PV Solar
    • Natural refrigerant – Ozone friendly
    • Mains pressure hot water

    How it works

    1. Cold water is drawn from the tank into the heat pump unit.

    2. A fan draws air through an evaporator where the heat from the air is transferred to a natural refrigerant gas.

    3. The heated gas is circulated around a compressor, increasing the pressure and temperature.

    4. The hot gas passes through a heat exchanger to heat the cold water, which is then pumped back into the top of the storage tank ready to use.
