No. The Law of 19 December 2008 on water prohibits the direct or indirect discharge of water as well as other solid or gaseous substances. Groundwater heat pumps cannot therefore be authorised in Luxembourg.
What do I have to take into consideration when planning a geothermal heat pump?
The size of the installation must be calculated in accordance with VDI (Association of German Engineers) Guideline 4640. Ask your chosen drilling company for information on this subject.
In addition, you can also have a heat load calculation and a geological survey carried out in order to establish the sizing.
You must ensure that you have obtained all necessary permits before the works start.
The exact date of the start of drilling must then be notified to the water management authority in advance. Ensure that the drilling company and the installer coordinate their schedules.
