Geowell Erdwärme GmbH & Co.KG

What Geowell Erdwärme GmbH & Co.KG does

Geowell Erdwärme GmbH & Co. KG is a German specialty contractor that delivers turnkey geothermal drilling and heat pump installation services across residential, commercial, industrial, public-sector, and district-heating customer segments. The company operates from two locations — Marl in North Rhine-Westphalia (northern headquarters) and Penzberg in Upper Bavaria — and runs a fleet of twelve proprietary drilling rigs with an in-house workforce of approximately 50 employees. Its core technology is the creation of geothermal boreholes, typically 50–250 meters deep, in which brine-filled earth heat probes circulate to deliver constant subterranean temperatures to sole/water heat pumps for heating, cooling, and hot water generation. Project capacity spans 3 kW for single-family homes up to 1,500 kW for large industrial and district installations. To date, the company has executed more than 5,000 construction projects and 3 million drilling meters, with reference projects in Germany and internationally in Baku, Madrid, and Zagreb.

The company is organized as a German Kommanditgesellschaft (KG) with Geowell Erdwärme Geschäftsführungs GmbH as the personally liable general partner, and is led by managing directors Frank Piecha and Michael Müller. Its go-to-market is enterprise field sales driven by direct customer outreach, site visits, and custom project proposals, with customers initiating contact via a website inquiry form or phone. Revenue is generated through one-time project fees for geothermal drilling and full turnkey delivery, plus professional services for planning, Geothermal Response Testing, and permit applications; no pricing is published and all quotes are project-specific. The company holds DVGW-Arbeitsblatt W 120 specialist certification through Zertifizierung Bau e.V., making its projects eligible for the Bundesförderung für effiziente Gebäude (BEG) subsidy program, and maintains memberships in Bundesverband Wärmepumpe, Soka-Bau, Verband Bergbau Geologie Umwelt, and Erdwärme Gemeinschaft Bayern. Notable enterprise customers include IKEA (Berlin and Wuppertal), SAP (Hamburg), Fiducia & GAD IT AG (Karlsruhe), Gascade Gastransport (Kassel), TenneT (Bayreuth), WAGO Kontakttechnik (Minden), PAJUNK Medizintechnik (Geisingen), Vector Informatik (Karlsruhe), and Medatixx (Bamberg), alongside public-sector clients such as GAG Ludwigshafen, Gemeinde Huglfing, and Energie Schifferstadt.

Products and services

• Vorprüfung (Pre-Inspection and Geological Assessment)
• Planung und Genehmigung (Planning and Permitting)
• Sondenbohrung (Earth Heat Probe Drilling) Core drilling service executing the geothermal borehole (typically 50–250 m depth, up to 250 m) and installation of high-density polyethylene earth heat probes filled with heat-transfer brine. Capacity range from 3 kW residential installations to 1,500 kW industrial systems. DVGW W 120 certified. Delivered with the company's own 12 drilling rigs and field teams for residential, commercial, industrial, and public sector clients.
• Anbindung (Brine Pipe and Heat Pump Connection) Service connecting the geothermal probe in the borehole to the building's heating circuit and heat pump via horizontal brine piping laid in trenches up to the building entry point. Includes pressure testing of the brine circuit. Delivered for residential, commercial, industrial, and public sector geothermal installations.
• Inneninstallation (Heat Pump Interior Installation) Interior installation service placing and commissioning the sole/water or brine/water heat pump inside the building, connecting it to the geothermal probe circuit and the building's heating distribution (and domestic hot water preparation). For residential, commercial, industrial, and public sector customers with renewable heating installations.
• Dokumentation (Project Documentation and Handover) Project handover service compiling the borehole log, drilling protocol, brine pressure-test record, Thermal Response Test (TRT) results where applicable, pump and probe specifications, and as-built drawings. Required documentation for warranty claims, government subsidy compliance (BAFA/KfW/BEG), and future service of the geothermal installation.

Broad incumbents

• Bosch Thermotechnology: Division of Bosch producing heating and hot water solutions including geothermal heat pumps. Comparable as an incumbent that pulls through end-customer demand for the geothermal drilling and installation services Geowell provides.
• Keller Group plc: International geotechnical and ground engineering contractor with significant operations in Germany. Provides specialist foundation and ground engineering services with overlap into geothermal and ground-source drilling adjacent to Geowell's borehole work.
• Bauer AG: Large German foundation engineering and drilling contractor with global reach. Provides geotechnical, foundation, and drilling services including geothermal wells; competes with Geowell on the drilling/civil engineering side while operating at a much broader scale.
• Stiebel Eltron: Major German manufacturer of heat pumps, heating, and hot water systems. Comparable because heat pumps are the demand driver for Geowell's drilling services; Stiebel is also active in promoting geothermal heat pump adoption through industry associations like Bundesverband Wärmepumpe.
• Viessmann: Leading German manufacturer of heating, industrial, and refrigeration systems with a strong heat pump portfolio. Comparable as a key player in the German heat pump ecosystem whose installed base drives the underlying drilling demand Geowell serves.

Emerging players

• Roth Werke GmbH: German manufacturer of energy systems including heat pump-compatible surface heating and geothermal energy solutions. Comparable to Geowell as a complementary player in the German geothermal heat pump value chain.

Direct peers

• GTN Geothermie Neubrandenburg GmbH: German geothermal services provider offering drilling, well construction, and geothermal plant services. Comparable to Geowell as a domestic geothermal drilling contractor with similar technical capabilities around wellfield operations.
• Züblin Spezialtiefbau GmbH: German specialist civil engineering and foundation contractor within the Strabag group. Overlaps with Geowell in geothermal borehole drilling for large infrastructure and real estate projects (Geowell has executed projects for Züblin, e.g., Henninger Turm and Bertolt-Brecht-School), and competes in the same shallow geothermal drilling segment.
• geoENERGIE Konzept GmbH: German specialist for shallow and deep geothermal projects including borehole heat exchangers and ground-source heat pump installations. Closely comparable to Geowell as a German-based turnkey geothermal drilling and heat pump contractor.
• Erdwärme Süd GmbH: Southern German geothermal drilling contractor specializing in borehole heat exchangers for residential, commercial, and district projects. Directly competes with Geowell's Penzberg office in the Bavarian market.
