Papa, wieso müssen wir kein teures Heizöl kaufen?

Heliotherm ground-source heat pump with CO2 probe
Ground-source heat pump with CO2 ground probe 
Ground-source heat pumps with CO2 probes harness the free energy stored underground. The CO2 probes are installed by drilling deep down into the ground. The number and length of the CO2 probes depends on the required heat output.

CO2 circulates within the CO2 probes. This can evaporate, even at extremely low temperatures in the ground. Compared to conventional working fluids, CO2 is completely safe for the environment in this form.
CO2 probes can therefore be used in water protection and conservation areas.
Ground-source heat pumps with CO2 probes have two circuits, each with its own working fluid.
The heated CO2 (carbon dioxide) rises naturally inside the CO2 probes. When it reaches the CO2 heat exchanger, the gas transfers its heat to the working fluid of the heat pump. The energy transfer causes the CO2 to condense to a liquid. This flows back down along the inside wall of the pipe where it then absorbs heat again.

How the CO2 ground probe worksFig.4 How the CO2 ground probe works










The working fluid travels as a gas through the refrigerant pipes to the heat pump’s compressor (in the second circuit), where it is pressurised and thus heated to a higher temperature. The heat from the hot gas is then transferred to the heating water (underfloor heating) in the heat exchanger. This heat transfer causes the working fluid to condense back to liquid. The expansion valve (dsi technology) is used to bring the working fluid down to a low temperature to enable energy to be absorbed again in the CO2 heat exchanger.
The heat pump cycle is then repeated.
 


BENEFITS of the Heliotherm ground-source heat pump with CO2 probe: :

  • Exceptionally low operating costs since a drive pump is not needed in the CO2 probe cycle.
  • The ground-source heat pump with CO2 probe can also be used in water protection and conservation areas.
  • Possible coefficient of performance of up to 5.5.
    82%     of your heating energy is thus free solar power from your own garden.
  • The closed loop makes the system totally safe and completely maintenance-free.
  • The DSG housing from Heliotherm enables the heat pump to run exceptionally quietly.
  • No heat loss due to additional heat exchangers.
  • The Heliotherm web control® regulation system allows you to operate your heat pump online from anywhere in the world.
