What Maurer Energie- und Ingenieurleistungen GmbH & Co. KG does

Maurer Energie- und Ingenieurleistungen GmbH & Co. KG (trading as Maurer EIL) is a German engineering and energy services firm headquartered in Schramberg-Sulgen, Baden-Württemberg. Founded in 1933 by Hermann Maurer as a tile stove and hearth construction business, the company has evolved into a third-generation family-owned Mittelstand firm operating as the planning and energy services hub of the Maurer Group, which comprises 12 subsidiaries and approximately 500 employees across Baden-Württemberg and Saxony. Since 2007 the company has been led jointly by Clemens Maurer (Dipl.-Kfm.) and Tobias Maurer (Dipl.-Ing. (FH)).

The company operates two service divisions. The engineering services division (Ingenieurdienstleistungen) delivers HOAI-compliant specialist planning for heating, cooling, climate, ventilation, sanitation, and building automation across industrial, commercial, residential, and public-sector projects. The energy services division (Energiedienstleistungen) delivers energy certificates, KfW funding documentation, ISO 50001/14001 management systems, energy concepts, and energy contracting. Notable technical capabilities include a custom ice storage heating/cooling system developed for Kreissparkasse Rottweil (670 m³ water storage with a 150 kW heat pump), industrial waste heat recovery concepts for production facilities such as Simon BETEK's 6,500 m² brazing hall, and hybrid heat pump systems integrating gas boilers for bivalent operation. The company is a member of the B.E.N. biomass energy network and partners with Südwärme AG for energy contracting.

Maurer EIL generates revenue through professional services fees (HOAI-based planning and consulting) and managed/contracting services (energy supply contracts, where the company delivers heat to customer buildings). Go-to-market is direct enterprise field sales supported by project-based references and digital marketing via its website, Facebook, and Instagram channels. The firm serves a named enterprise roster including Bosch, Trumpf, Arburg, Duravit, Karl Storz, and ALDI SÜD, alongside public sector clients and private homeowners, with a stated geographic focus on the Black Forest-Baar-Heuberg region of Baden-Württemberg and an eastern presence in Saxony via DZH-Scheptiz GmbH. The company claims 15,700 tonnes of CO2 savings annually delivered through customer heating modernizations.

Broad incumbents

• Bosch Thermotechnology: Bosch's heating and hot-water division supplies HVAC and heat-pump systems across Germany and increasingly bundles them with energy services—overlapping end customers and the same industrial/commercial decarbonization thesis Maurer EIL addresses.
• E.ON Energy Solutions (innogy / E.ON SE): E.ON's energy-solutions arm delivers integrated energy efficiency and heat-supply services across Germany, competing with Maurer EIL for industrial, commercial and municipal energy contracting projects; broader portfolio but overlapping target customers.
• Vaillant Group: European heating, ventilation and heat-pump group headquartered in Remscheid, Germany; comparable to Maurer EIL on heat-pump and heating-modernization offerings targeting German residential and commercial customers.
• Viessmann Group: Leading German manufacturer of heating, industrial and refrigeration systems, also offering energy services and heat-pump solutions; comparable to Maurer EIL on the equipment-side of integrated heat projects and increasingly competing on energy contracting.
• Stiebel Eltron Deutschland: German heat-pump and HVAC manufacturer with a strong focus on renewable heating technologies; comparable to Maurer EIL on the technical solutions portfolio (heat pumps, hybrids) and competes for the same subsidy-driven modernization demand.
• ENGIE Deutschland GmbH: Germany's largest multi-technical and energy-services provider, offering integrated facility management, HVAC, and energy contracting for industrial, commercial and public-sector clients—directly overlapping with Maurer EIL's Ingenieur- and Energiedienstleistungen portfolio at far greater scale.

Regional players

• EnBW Energie Baden-Württemberg AG: Home-region Stuttgart-based utility offering energy solutions, district heating, and decarbonization services for BW customers—the same state in which Maurer EIL concentrates its operations and where EnBW is both a competitor for utility-scale decarbonization work and a potential partner.
• MVV Energie AG: Regional German energy company providing district heating, energy contracting, and efficiency services to industrial and municipal customers; comparable in service model (planning + energy contracting) and regional positioning to Maurer EIL.

Direct peers

• GETEC Group: German energy-services specialist delivering planning, contracting, and operation of decentralized energy plants for industrial and commercial real estate—the closest functional peer to Maurer EIL's Ingenieur- and Energiedienstleistungen combination.
• Dalkia Deutschland GmbH: Dalkia specializes in centralized heating, cooling, and energy networks including waste-heat recovery and contracting—precisely the services Maurer EIL delivers via Südwärme and direct to industrial customers. Identical go-to-market as an integrated heat-supplier / contractor.
