What Installation Zeitz does

Installation Zeitz eG is a registered German cooperative (Genossenschaft, GnR-3380 at Amtsgericht Stendal) operating as a traditional SHK/HVAC craft-trade business headquartered at Auf den Gebinden 20, 06712 Zeitz, Sachsen-Anhalt. The company designs, installs, and maintains heating (Heizung), sanitation (Sanitär), ventilation (Lüftung), air conditioning (Klima), and external lightning protection (Äußerer Blitzschutz) systems. Its core technology is trade-craft execution — qualified engineers and master craftsmen deliver project planning, installation, and maintenance — supported by certifications under DIN 18024/18025 (barrier-free construction), DIN EN 62305 (lightning protection), TRF 88 (liquefied gas), and authorized gas/water installation status. The company maintains brand partnerships with Viessmann, Buderus, DEWE, Wiedemann, Weishaupt, GC, Richter+Frenzel, and Junkers for equipment supply.

The business operates a dual go-to-market: (1) project-based direct field sales for residential (Wohnungsbau), commercial (Gewerbebau), logistics, healthcare, heritage, and private customers nationwide, and (2) a warehouse direct-sales (Lagerdirektverkauf) channel at the Zeitz facility selling installation materials, replacement parts, and liquified gases distributed via partnerships with Rheingas and Progas. Notable named customers include Sparkasse Burgenlandkreis, Globus SB-Märkte, Schaeffler, Jowat-Klebstoffe, Goldeck-Süßwaren, Flughafen Leipzig, and heritage sites including Dom Zeitz and Moritzburg Zeitz. Revenue is generated through one-time installation contracts and hardware sales under a quote-based pricing model; no public pricing or revenue disclosure exists.

Installation Zeitz is governed as a cooperative under German law: Martin Schwan and Michael Hildebrandt sit on the managing board (Geschäftsführender Vorstand), Jens Winter chairs the supervisory board and leads the Heating division, and Jenny Geithner serves as commercial director. The company is an active Ausbildungsbetrieb training Anlagenmechaniker für Sanitär-, Heizungs- und Klimatechnik apprentices, with a 2025 first-year cohort publicly visible. Distribution of complex total-package projects ('fertiges Bad') is enabled by a long-term subcontractor network across multiple trades. No external parent, private equity, or institutional funding is present.

Others

• Viessmann Generations Group: German heating, industrial, and refrigeration-systems manufacturer (also an Installation Zeitz partner). Indirect peer — supplies the heating technology and partner-network training that SHK installers depend on, and increasingly competes on climate and heat-pump solutions.
• Bosch Thermotechnik (Buderus): Manufacturer of Buderus heating and hot-water systems (an Installation Zeitz partner brand). Comparable as a supply-side participant in the same heating-installation value chain; not a direct installer competitor but sets the technology and training standards installers must follow.
• Weishaupt Group: German manufacturer of burners, heating systems, heat pumps, and solar thermal technology (also an Installation Zeitz partner). Comparable as an adjacent supplier whose product portfolio overlaps the heating line Installation Zeitz installs and services.

Broad incumbents

• Gegenbauer Group: Berlin-based building-services and technical facility-management company with a long German history covering HVAC, plumbing, and energy services. Overlaps directly with Installation Zeitz's residential and commercial installation work, particularly in Berlin and eastern Germany.
• Dalkia Deutschland: German subsidiary of EDF's Dalkia, focused on energy-efficient HVAC, heating, and cooling solutions for commercial and industrial buildings. Comparable in heating and climate-control installation competencies, with larger-scale project capacity.
• Dussmann Group: German technical building-services and facility-management provider covering HVAC, plumbing, electrical, and energy management. Overlaps with Installation Zeitz's commercial MEP installation work and operates nationally.
• Stiebel Eltron Group: Major German manufacturer of heat pumps, heating, ventilation, and hot-water systems; also runs installation and service operations in Germany. Comparable because it both supplies products similar to those Installation Zeitz installs (Viessmann/Buderus/Junkers) and competes on the installation side for heat-pump and HVAC retrofit projects.
• CAVERION Deutschland: German arm of the Nordic CAVERION Group providing HVAC, plumbing, and building-automation services across commercial and industrial sites. Comparable SHK/MEP scope, with deeper digital monitoring and lifecycle-service capabilities than a single-region installer like Installation Zeitz.
• ENGIE Deutschland: Large German subsidiary of ENGIE Group providing HVAC, building services, and technical facility management for commercial and industrial customers. Operates as a broad incumbent across the same SHK/MEP value chain as Installation Zeitz, but at national scale and with broader digital and service-contract offerings.
• Wisag: Major German technical building-services and facility-management group delivering HVAC, plumbing, electrical, and energy services. Comparable to Installation Zeitz in core MEP disciplines but with a national footprint, service-contract layer, and significantly larger scale.
