Geothermal drilling - this is how it’s done

Geothermal drilling - this is how it’s done. Heizungsmacher shows in this video step by step how a geothermal drilling proceeds. In the first step, a huge drilling machine is placed on the site of the builder. Using a drill rig with a diamond drill head attached to the end, a water/air mixture is pumped 220 metres into the ground via a double pipe string. In the process, soil, rock and bedrock are conveyed to the surface through the inner casing of the drill pipe and pumped out. As soon as the final depth is reached, the drill pipe is pulled out again and instead a so-called pipe bundle is inserted into the drilled hole. After the installation of the geothermal heat pump, this pipe bundle transports the heat from the ground to the heat pump. Finally, the borehole is backfilled with a concrete mix and the heat pump can be connected to the geothermal probe and put into operation.

Incroyable merci pour cette présentation

[@kaloryfer99999]

I wonder what temperature can they reach at 220 meters.

[@cupwalker24.7]

Thats like 2 days of per diem 😂😂😂 and drilling

[@mjoelnir1899]

220 meters is hardly a "geothermal Drilling". Geothermal means you tap the heat radiating from the earth core. 220 m is not enough debt to do that.
This is ground based energy not geothermal.
It is strange how many so called experts do not get the difference.

[@heizungsmacher]

thanks for your clarification. You are obviously right. We tried to make the video as easy to find as possible. Since the wording "geothermal" is commonly more used, we went for that title.

[@loveyourtie]

It uses the constant temperature under the ground for heating and cooling. Your definition of what geothermal is too narrow.

[@mjoelnir1899]

@@loveyourtie Definitions are useless when they are to wide, than one has to use whole sentences to describe something, instead of using one word, to explain what one means. If you want to use the more sexy geothermal instead of the correct ground based, than at least add shallow to geothermal.
When I started out geothermal was only used to describe the power resulting from the heat radiating from the earth core. Ground based system were not widely used. Now people seem to use geothermal wider and it does not any longer describe a certain thing exactly. It is especially frustrating as there is a good and useful word for what you use, ground based.
