JANSEN vertex special ground source heat loop

Today, the ground source heat loop is the most versatile method used to obtain heat and cooling from the ground. The JANSEN vertex ground source heat loop is particularly suitable for hot water preparation and for heating and cooling buildings.

With the vertex special ground source heat loop, Jansen offers a system for special requirements: deep bores, larger or special pipe dimensions, and even custom fabrications. In particular, the JANSEN vertex with a diameter or 50 mm impresses with its unique hydraulics, high resistance to pressure and extreme robustness for hard construction site conditions.


  • Highest efficiency
  • Heating and cooling in one system
  • Very little space required
  • Low operating costs
  • Does not produce any noise emissions
  • Low hydraulic pressure


  • PE 100 RC (resistant to cracking) or PE 100 RT (high-temperature resistant)
  • PERT (High-temperature ground loops)


  • Heating
  • Free cooling
  • Air-conditioning
  • Hot water production
  • Keeping open areas free of snow and ice
