Thermann X Split Heat Pump

Combining a Japanese and Australian engineering, The Thermann X 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

Animation showing how a heat pump hot water system operates.
  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.
