Energy gain from a borehole with the RAUGEO probe

For efficient heating and cooling

With this REHAU system energy is extracted from the ground through a closed circuit. The water circulating in the RAUGEO probe serves as heat carrier medium. The RAUGEO PE-Xa probe is installed without connections in the ground. With the help of a heat pump the extracted heat is raised to the temperature needed for heating.

  • • At least 75% of the energy comes from the ground

  • • No need for joints in the soil ensures highest operational reliability

  • • PE-Xa material is not sensitive to notches and grooves

  • • Optimal safety during insertion into the borehole

  • • Simple insertion even into the tightest boreholes

  • • Heat storage up to 95°C is possible

  • • Cost-effective heating from ground source energy

  • • RAUGEO PE-Xa probe is extremely reliable in service, small bending radius elliminates the need for joints or other connections at the probe base
  • • Stable up to temperatures of 95°C, thus the RAUGEO PE-Xa probe can be used for heat storage purposes
  • • RAUGEO PE-Xa probe base is protected by a special tough resin
  • • The RAUGEO PE-Xa probe can be connected by means of electrofusion sleeve or by mean of REHAU – compression sleeve under all climatic conditions
  • • Applicable up to a depth of 300 m

  • • For ground source heating/cooling using heat pump

  • • Optimal in combination with underfloor heating and cooling in the house

  • • Open areas
