Company near Mainz that builds ground collector heating systems?

Hello everyone!

Does anyone know a company in Rheinhessen or near Mainz that builds earth collector heating systems?

Or geothermal baskets or trench collectors...

For those interested, I found this:

- Brunnenbau Erdwärme Heth GmbH from 64653 Lorsch offers geothermal baskets

- Noelke Ausbau has an office in Mainz and offers ground collectors

- Metternich Haustechnik from 51570 Windeck also offers ground collectors for the Rheinhessen region

- Gergen Geothermie has a partner company in Kastellaun that offers direct evaporation collectors and direct evaporation probes (only 30m depth)

I couldn't find more, or does anyone else know something?
